<br />
&lt;/server&gt;
<br />
&nbsp;&nbsp;
其中ClusterConfig配置在前面JavaGroups的介�l�详�l�介�l�，其它配置比较���单，需要进一步了(ji��n)解请参见TreeCache文档�?
<br />
&nbsp;&nbsp; 一、Cache分类
<br />
&nbsp;&nbsp;
TreeCache按功能分��Z���c�：(x��)本地(Local)Cache、复�?Replication)Cache和失�?
(Invalidation)Cache。本地Cache只应用于本地环境�Q�后两个Cache可应用于分布式环境，其中�Q�在分布式环境中�Q�复制Cache
当一个Cache实例的一个节点值发生变化时�?x��)将变化复制到其它实例中�Q�而失效Cache是当一个Cache实例的一个节点值发生变化时�?x��)将其它实例的�?
应节点的��D��为空�Q�让光���新去获得该��|��可通过�q�种方式�~�存大对象以减少在实例中复制对象的代仗���分布式Cache�Q�复制和失效Cache�Q�又分�ؓ(f��)两种�Q?
同步�Q�REPL_ASYNC�Q�和异步�Q�REPL_SYNC�Q�，同步Cache是在一个Cache实例做修�Ҏ(gu��)���Q�等待变化应用到其它实例后才�q�回�Q�而异�?
Cache是在一个Cache实例做修�Ҏ(gu��)���Q�即刻返回。其配置见下�Q?
<br />
!--
<br />
&nbsp; Valid modes are LOCAL
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; REPL_ASYNC
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; REPL_SYNC
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; INVALIDATION_ASYNC
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; INVALIDATION_SYNC
<br />
-&gt;
<br />
attribute name="CacheMode"&gt;REPL_SYNC&lt;/attribute&gt;
<br />
<br />
&nbsp;&nbsp; 二、事务和�q�行(Transaction And Concurrent)
<br />
&nbsp;&nbsp;
TreeCache是一�U�事务Cache�Q�与JDBC一��P��其包括两斚w��内容�Q�锁和隔��ȝ�别。锁分�ؓ(f��)�(zh��n)�观锁和乐观锁，当��用�?zh��n)�观锁�Ӟ��分��?f��)五个隔离�U�别�Q?
分别是SERIALIZABLE、REPEATABLE_READ
(default)、READ_COMMITTED、READ_UNCOMMITTED和NONE�Q�隔��ȝ�别逐步减弱。乐观锁也叫版本锁，其对数据�q�行�?
作时�Q�将其复制到临时区，操作之后���版本与原有数据比较�Q�如果一致则���递增版本�q�写回，如果不一致则回滚�Q�由于乐观锁仅在复制出数据和提交数据时对数据�?
锁，所以�ƈ行度更高�Q�但如果写操作比较频�J�地话则�Ҏ(gu��)��出现冲突��D��回滚。TreeCache默认使用�(zh��n)�观锁。��用TreeCache�Ӟ��需要��用容器提�?
的事务管理器�Q�一般��JBossTransactionManagerLookup和GenericTransactionManagerLookup�Q?
前者应用于JBOSS服务器，后者应用于其他服务器，也可使用DummyTransactionManagerLookup用于���试。如上介�l�的配置�?
下：(x��)
<br />
attribute name="NodeLockingScheme"&gt;OPTIMISTIC&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute
name="IsolationLevel"&gt;REPEATABLE_READ&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute
name="TransactionManagerLookupClass"&gt;org.jboss.cache.DummyTransactionManagerLookup&lt;/attribute&gt;
<br />
<br />
<br />
&nbsp;&nbsp; 三、逐出�{�略(Eviction Policy)
<br />
&nbsp;&nbsp;
�׃��内存数量的局限，不可能将所有的Cache数据存放在内存中�Q�但使用内存辑ֈ�一定极限时�Q�会(x��)���部分数据清除出内存�Q�保存到其它持久媒质中，定义的什�?
时候清除、如何清除的�{�略���是逐出�{�略。自定义一个逐出�{�略需要实现org.jboss.cache.eviction.EvictionPolicy�?
org.jboss.cache.eviction.EvictionAlgorithm�?
<br />
g.jboss.cache.eviction.EvictionQueue
和org.jboss.cache.eviction.EvictionConfiguration四个接口�Q�系�l�提供了(ji��n)LRU(Least
recently used�Q�最�q�最������?、LFU(Least Frequently Used最不经�怋��?、FIFO(First In
First Out先进先出)、MRU(Most Recently
Used最�q�最�l�常使用)四种实现�Q�详�l�参见org.jboss.cache.eviction包的源代码。配�|�如下：(x��)
<br />
&lt;attribute name="EvictionPolicyConfig"&gt;
<br />
&nbsp;&nbsp; &lt;config&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute
name="wakeUpIntervalSeconds"&gt;5&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;region name="/_default_"&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute name="maxNodes"&gt;5000&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute
name="timeToLiveSeconds"&gt;1000&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/region&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;region name="/org/jboss/data"
<br />
policyClass="org.jboss.cache.eviction.FIFOPolicy"&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute name="maxNodes"&gt;5000&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/region&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;region name="/test/"
policyClass="org.jboss.cache.eviction.MRUPolicy"&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute name="maxNodes"&gt;10000&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/region&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;region name="/maxAgeTest/"&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute name="maxNodes"&gt;10000&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute
name="timeToLiveSeconds"&gt;8&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;attribute name="maxAgeSeconds"&gt;10&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/region&gt;
<br />
&nbsp;&nbsp; &lt;/config&gt;
<br />
&lt;/attribute&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp; 四、Cache加蝲
<br />
&nbsp;
�׃��逐出�{�略的存在，那么当我们重新需要获得一个原来在�~�存中但���由内存原因被逐出的数据时�Q�就需要定义一�U�加载策略，使地可以重新扑֛�数据�Q�同
�Ӟ��Cache加蝲也肩负在���数据逐出时将数据保存到持久媒质的责�Q�?
<br />
&nbsp;
�Ҏ(gu��)�����数据保存媒质的不同�Q�Cache加蝲包括F(xi��n)ileCacheLoader、JDBCCacheLoader�{�等�Q�可以同时��用多�U�加载器来灵�z�d���?
加蝲�{�略。例见下�Q?
<br />
&lt;attribute name="CacheLoaderConfiguration"&gt;
<br />
&nbsp;&nbsp;&nbsp; &lt;config&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;passivation&gt;false&lt;/passivation&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;preload&gt;/&lt;/preload&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;shared&gt;true&lt;/shared&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;cacheloader&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&lt;class&gt;org.jboss.cache.loader.ClusteredCacheLoader&lt;/class&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;properties&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; timeout=1000
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/properties&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;async&gt;true&lt;/async&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&lt;fetchPersistentState&gt;false&lt;/fetchPersistentState&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ignoreModifications&gt;false&lt;/ignoreModifications&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;purgeOnStartup&gt;false&lt;/purgeOnStartup&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/cacheloader&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;cacheloader&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&lt;class&gt;org.jboss.cache.loader.JDBCCacheLoader&lt;/class&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;properties&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.table.name=jbosscache
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.table.create=true
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.table.drop=true
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.table.primarykey=jbosscache_pk
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.fqn.column=fqn
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.fqn.type=varchar(255)
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.node.column=node
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.node.type=longblob
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.parent.column=parent
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.driver=com.mysql.jdbc.Driver
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
cache.jdbc.url=jdbc:mysql://localhost:3306/jbossdb

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.user=root
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; cache.jdbc.password=
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/properties&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;async&gt;true&lt;/async&gt;
<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;/cacheloader&gt;
<br />
&nbsp;&nbsp;&nbsp; &lt;/config&gt;
<br />
&lt;/attribute&gt;
<br />
<br />
我们���通过定制如上的配�|�信息以更有效地使用JBossCache。详�l�情况可参考JBoss TreeCache参考文档和范例�?

&nbsp;&nbsp;&nbsp; 1). 安装JDK 1.5 或更高版本， �q�����|�JAVA_HOME 环境变量;<br />
&nbsp;&nbsp;&nbsp; 2). 安装tomcat 6 ;<br />
&nbsp;&nbsp; <br />
二、配�|�过�E?br />
&nbsp;&nbsp;&nbsp; 1.生成 server key �Q?br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 以命令行方式切换到目�?tomcat_HOME%�Q�在command命��o(h��)行输入如下命令（jdk1.4以上带的工具�Q�：(x��) <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keytool -genkey -alias tomcat -keyalg RSA -keypass changit -storepass changit -keystore server.keystore -validity 3600 <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 用户名输入域名，如localhost�Q�开发或���试用）(j��)或hostname.domainname(用户拥有的域�?�Q�其它全部以 enter 跌����Q�最后确认，<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 此时�?x��)�?JAVA_HOME%/bin下生成server.keystore 文�g�?br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 注：(x��)参数 -validity 指证书的有效�?�?�Q�缺省有效期很短�Q�只�?0天�?br />
&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp; 2.���证书导入的JDK的证书信��d���?<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
�q�步对于tomcat的SSL配置不是必须�Q�但对于CAS
SSO是必��ȝ���Q�否则会(x��)出现如下错误�Q�edu.yale.its.tp.cas.client.CASAuthenticationException:
Unable to validate ProxyTicketValidator。。�?br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 导入�q�程�?步，�W�一步是导出证书�Q�第二步是导入到证书信�Q库，命��o(h��)如下�Q?br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keytool -export -trustcacerts -alias tomcat -file server.cer -keystore&nbsp; server.keystore -storepass changit<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
keytool -import -trustcacerts -alias tomcat -file server.cer -keystore&nbsp;
%JAVA_HOME%/jre/lib/security/cacerts -storepass changeit<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 如果有提�C�，输入Y���可以了(ji��n)�?br />
&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;其他有用keytool命��o(h��)�Q�列��Z��任证书库中所有已有证书，删除库中某个证书�Q�：(x��)<br />
&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;keytool -list -v -keystore %JAVA_HOME%/jre/lib/security/cacerts<br />
&nbsp;&nbsp;&nbsp;keytool -delete -trustcacerts -alias tomcat&nbsp; -keystore&nbsp; %JAVA_HOME%/jre/lib/security/cacerts -storepass changit</p>
<p>&nbsp;&nbsp;3.配置tomcat :<br />
&nbsp;&nbsp;&nbsp;修改%TOMCAT_HOME%"conf"server.xml�Q�以文字�~�辑器打开�Q�查找这一行：(x��)<br />
&nbsp;&nbsp;&nbsp;xml 代码<br />
&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;���之后的那段的注释去掉，�q�加�?keystorePass�?qi��ng)keystoreFile属性�?br />
&nbsp;&nbsp;&nbsp;注意�Q�tomcat不同版本配置是不同的:<br />
&nbsp;&nbsp;&nbsp;tomcat4.1.34配置�Q?br />
&nbsp;&nbsp;&nbsp;xml

keystorePass="changit"/&gt;&nbsp; tomcat5.5.9配置�Q?br />
&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;xml 代码<br />

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keystorePass="changit"/&gt;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;tomcat5.5.20配置(此配�|�同样可用于tomcat6.0)�Q?br />
&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;xml 代码<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&lt;Connector protocol="org.apache.coyote.http11.Http11Protocol"&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; port="8443" maxHttpHeaderSize="8192"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; maxThreads="150" minSpareThreads="25" maxSpareThreads="75"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; enableLookups="false" disableUploadTimeout="true"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acceptCount="100" scheme="https" secure="true"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; clientAuth="false" sslProtocol="TLS"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keystoreFile="server.keystore"&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keystorePass="changit"/&gt;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;tomcat6.0.10配置�Q?br />
&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;xml 代码<br />
&nbsp;&nbsp;&nbsp;&lt;Connector protocol="org.apache.coyote.http11.Http11NioProtocol"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; port="8443" minSpareThreads="5" maxSpareThreads="75"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; enableLookups="true" disableUploadTimeout="true"&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acceptCount="100"&nbsp; maxThreads="200"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; scheme="https" secure="true" SSLEnabled="true"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; clientAuth="false" sslProtocol="TLS"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keystoreFile="server.keystore"&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keystorePass="changit"/&gt;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;tomcat6支持3�U�，请参考以下文档：(x��)<br />
&nbsp;&nbsp;&nbsp;<a >http://tomcat.apache.org/tomcat-6.0-doc/ssl-howto.html</a> <br />
&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;4.验证配置<br />
&nbsp;&nbsp;&nbsp;讉K�� <a href="https://localhost:8443/">https://localhost:8443/</a><br />
&nbsp;&nbsp;&nbsp;&lt;connector protocol="org.apache.coyote.http11.Http11NioProtocol"&gt;&lt;/connector&gt;<br />
&nbsp;&nbsp;&nbsp;<br />
&nbsp;&nbsp;5. 如果默认想用HTTPS 方式�q�行�|�站, 可以作如下配�|?<br />
&nbsp;&nbsp;一般Tomcat默认的SSL端口��h��8443�Q�但是对于SSL标准端口��h��443�Q?br />
&nbsp;&nbsp;�q�样在访问网��늚�时候，直接使用https而不需要输入端口号���可以访问，�?a href="https://localhost/">https://localhost</a><br />
&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;1).non-SSL HTTP/1.1 Connector定义的地方，一般如下：(x��)<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;Connector port="80" maxHttpHeaderSize="8192"&nbsp; scheme="https" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; maxThreads="500" minSpareThreads="25" maxSpareThreads="75" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; enableLookups="false" redirectPort="443" acceptCount="100" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; connectionTimeout="20000" disableUploadTimeout="true" /&gt;&nbsp;&nbsp; <br />
&nbsp;&nbsp;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ���其中的redirectPort端口��h��为：(x��)443 </p>
<p>&nbsp;&nbsp; 2).SSL HTTP/1.1 Connector定义的地方，修改端口号�ؓ(f��)�Q?43�Q�如下：(x��)<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;Connector&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; port="443" maxHttpHeaderSize="8192" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; maxThreads="150" minSpareThreads="25" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; maxSpareThreads="75" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; enableLookups="false" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; disableUploadTimeout="true" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acceptCount="100" scheme="https" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; secure="true" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; clientAuth="false" sslProtocol="TLS" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; SSLEnabled="true"&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keystoreFile="e:/server.keystore" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; keystorePass="changit" /&gt;<br />
&nbsp;&nbsp;&nbsp; 3).AJP 1.3 Connector定义的地方，修改redirectPort�?43�Q�如下：(x��)&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&lt;Connector port="8009" <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; enableLookups="false" redirectPort="443" protocol="AJP/1.3" /&gt;<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br />
&nbsp;&nbsp;&nbsp;如上配置好后便可以用 <a href="https://localhost/">Https://localhost</a> 方式直接讉K��,无需输入端口�?</p>

<h2> How do I set the Transaction Timeout?</h2>
<p>Transaction timeout (unit is always seconds) can be configured in various ways:</p>
<p>This argument is the same no matter if you are using JBossTM(&lt;=4.0.5) or JBossJTA-Arjuna(&gt;=4.2).</p>
<ul>
    <li type="ul">
    <p>Globally:
    You can change this behavior globally by modifying the
    TransactionManagerService in /conf/jboss-service.xml (or
    /deploy/jta-service.xml for 4.0.3)</p>
    </li>
</ul>
<p><strong>Version &lt;= 4.0.5</strong></p>
<p>This part is the same for either JBossTM or JBossJTA and is the same for ejb2 and ejb3</p>
<ul>
    <li type="ul">
    <p>Per-method basis: Modifying the <span style="font-family: courier new,courier;">&lt;transaction-timeout&gt;</span>
    element inside the &lt;method&gt; element of a session or entity bean.
    This is located in the META-INF/jboss.xml deployment descriptor of a
    session bean. When the transaction timeout is specified at the method
    level, it overrides the default timeout. Further information about this
    element can be found in jboss-x.x.x/docs/dtd/jboss_4_0.dtd. Example
    taken from the testsuite:</p>
    </li>
</ul>
<ul>
    <li type="ul">
    <p>Using
    BMT: Calling
    javax.transaction.UserTransaction.setTransactionTimeout(int seconds).
    Please, be aware that this only applies to transactions started after
    this invocation on the same thread. Example:</p>
    </li>
</ul>

<p>Available option in deploy/jbossweb-tomcat.sar/META-INF/jboss-service.xml</p>
<p>or deploy/jboss-web.deployer/META-INF/jboss-service.xml</p>
<p>This
configuration options toggles usage of separate classloaders for web
modules. The JBoss unified classloader holds all the classes from
multiple web applications in one big classloader and may cause unwanted
interference.</p>
<p>Example</p>
<p>Imagine
web modules "sales.war" and "stock.war", both containing some version
of "utility.jar". In case "sales.war" uses version 1.0 and "stock.war"
requires version 2.0, turning off the unified web loader is the safest
solution. If you don't, the first loaded library will have priority,
and remains in the classloader till the reference count drops to zero.</p>
<p>The
disadvantage of using isolated classloaders: either you need to
duplicate the same library across multiple web modules, or add it to
the classpath of your server instance (default: lib/). The instance
libraries are defaults, they can be overridden when the web module
contains it's own custom versions.</p>
<p>The
configuration file contains a small comment about isolation of JSP
files as well, to separate two JSP files with the same name from two
different web modules. In JBoss 4.0.5, using non-precompiled JSP pages,
this seems to work fine, even with the JBoss unified web loader.</p>

on a production server.</p>
<p>mod_python is similar to (and inspired by) <a external="" >mod_perl</a> : It embeds Python within
Apache and loads Python code into memory when the server starts. Code stays in
memory throughout the life of an Apache process, which leads to significant
performance gains over other server arrangements.</p>
<p>Django requires Apache 2.x and mod_python 3.x, and you should use Apache&#8217;s
<a external="" >prefork MPM</a>, as opposed to the <a external="" >worker MPM</a>.</p>
<p>You may also be interested in <a external="" ><em>How to use Django with FastCGI, SCGI or AJP</em></a> (which also covers SCGI and AJP).</p>
<div   class="wmqeeuq"   id="s-basic-configuration">
<h2 id="basic-configuration">Basic configuration<a  title="Permalink to this headline">&#182;</a></h2>
<p>To configure Django with mod_python, first make sure you have Apache installed,
with the mod_python module activated.</p>
<p>Then edit your <tt literal="">httpd.conf</tt> file and add the following:</p>
<div>
<pre>&lt;Location "/mysite/"&gt;<br />
SetHandler python-program<br />
PythonHandler django.core.handlers.modpython<br />
SetEnv DJANGO_SETTINGS_MODULE mysite.settings<br />
PythonOption django.root /mysite<br />
PythonDebug On<br />
&lt;/Location&gt;<br />
</pre>
</div>
<p>...and replace <tt literal="">mysite.settings</tt> with the Python import path to your Django
project's settings file.</p>
<p>This tells Apache: "Use mod_python for any URL at or under '/mysite/', using the
Django mod_python handler." It passes the value of <a external="" ><em>DJANGO_SETTINGS_MODULE</em></a> so mod_python knows which settings to use.</p>
<div>
New in Django 1.0: The <tt literal="">PythonOption django.root ...</tt> is new in this version.</div>
<p>Because mod_python does not know we are
serving this site from underneath the <tt literal="">/mysite/</tt> prefix, this value needs to
be passed through to the mod_python handler in Django, via the <tt literal="">PythonOption
django.root ...</tt> line. The value set on that line (the last item) should
match the string given in the <tt literal="">&lt;Location ...&gt;</tt> directive. The effect of this
is that Django will automatically strip the <tt literal="">/mysite</tt> string from the front
of any URLs before matching them against your <tt literal="">URLConf</tt> patterns. If you
later move your site to live under <tt literal="">/mysite2</tt>, you will not have to change
anything except the <tt literal="">django.root</tt> option in the config file.</p>
<p>When using <tt literal="">django.root</tt> you should make sure that what's left, after the
prefix has been removed, begins with a slash. Your URLConf patterns that are
expecting an initial slash will then work correctly. In the above example,
since we want to send things like <tt literal="">/mysite/admin/</tt> to <tt literal="">/admin/</tt>, we need
to remove the string <tt literal="">/mysite</tt> from the beginning, so that is the
<tt literal="">django.root</tt> value. It would be an error to use <tt literal="">/mysite/</tt> (with a
trailing slash) in this case.</p>
<p>Note that we're using the <tt literal="">&lt;Location&gt;</tt> directive, not the <tt literal="">&lt;Directory&gt;</tt>
directive. The latter is used for pointing at places on your filesystem,
whereas <tt literal="">&lt;Location&gt;</tt> points at places in the URL structure of a Web site.
<tt literal="">&lt;Directory&gt;</tt> would be meaningless here.</p>
<p>Also, if your Django project is not on the default <tt literal="">PYTHONPATH</tt> for your
computer, you'll have to tell mod_python where your project can be found:</p>
<pre>&lt;Location "/mysite/"&gt;<br />
SetHandler python-program<br />
PythonHandler django.core.handlers.modpython<br />
SetEnv DJANGO_SETTINGS_MODULE mysite.settings<br />
PythonOption django.root /mysite<br />
PythonDebug On<br />
<strong>PythonPath "['/path/to/project'] + sys.path"</strong><br />
&lt;/Location&gt;<br />
</pre>
<p>The value you use for <tt literal="">PythonPath</tt> should include the parent directories of
all the modules you are going to import in your application. It should also
include the parent directory of the <a external="" ><em>DJANGO_SETTINGS_MODULE</em></a> location. This is exactly the same situation as
setting the Python path for interactive usage. Whenever you try to import
something, Python will run through all the directories in <tt literal="">sys.path</tt> in turn,
from first to last, and try to import from each directory until one succeeds.</p>
<p>An example might make this clearer. Suppose you have some applications under
<tt literal="">/usr/local/django-apps/</tt> (for example, <tt literal="">/usr/local/django-apps/weblog/</tt> and
so forth), your settings file is at <tt literal="">/var/www/mysite/settings.py</tt> and you have
specified <a external="" ><em>DJANGO_SETTINGS_MODULE</em></a> as in the above
example. In this case, you would need to write your <tt literal="">PythonPath</tt> directive
as:</p>
<div>
<pre>PythonPath "['/usr/local/django-apps/', '/var/www'] + sys.path"<br />
</pre>
</div>
<p>With this path, <tt literal="">import weblog</tt> and <tt literal="">import mysite.settings</tt> will both
work. If you had <tt literal="">import blogroll</tt> in your code somewhere and <tt literal="">blogroll</tt>
lived under the <tt literal="">weblog/</tt> directory, you would <em>also</em> need to add
<tt literal="">/usr/local/django-apps/weblog/</tt> to your <tt literal="">PythonPath</tt>. Remember: the
<strong>parent directories</strong> of anything you import directly must be on the Python
path.</p>
<div note="">
<p admonition-title="">Note</p>
<p>If you're using Windows, we still recommended that you use forward
slashes in the pathnames, even though Windows normally uses the backslash
character as its native separator. Apache knows how to convert from the
forward slash format to the native format, so this approach is portable and
easier to read. (It avoids tricky problems with having to double-escape
backslashes.)</p>
<p>This is valid even on a Windows system:</p>
<div>
<pre>PythonPath "['c:/path/to/project'] + sys.path"<br />
</pre>
</div>
</div>
<p>You can also add directives such as <tt literal="">PythonAutoReload Off</tt> for performance.
See the <a external="" >mod_python documentation</a> for a full list of options.</p>
<p>Note that you should set <tt literal="">PythonDebug Off</tt> on a production server. If you
leave <tt literal="">PythonDebug On</tt>, your users would see ugly (and revealing) Python
tracebacks if something goes wrong within mod_python.</p>
<p>Restart Apache, and any request to <tt literal="">/mysite/</tt> or below will be served by
Django. Note that Django's URLconfs won't trim the "/mysite/" -- they get passed
the full URL.</p>
<p>When deploying Django sites on mod_python, you'll need to restart Apache each
time you make changes to your Python code.</p>
</div>
<div   class="wmqeeuq"   id="s-multiple-django-installations-on-the-same-apache">
<h2 id="multiple-django-installations-on-the-same-apache">Multiple Django installations on the same Apache<a  title="Permalink to this headline">&#182;</a></h2>
<p>It's entirely possible to run multiple Django installations on the same Apache
instance. Just use <tt literal="">VirtualHost</tt> for that, like so:</p>
<div>
<pre>NameVirtualHost *<br />
<br />
&lt;VirtualHost *&gt;<br />
ServerName www.example.com<br />
# ...<br />
SetEnv DJANGO_SETTINGS_MODULE mysite.settings<br />
&lt;/VirtualHost&gt;<br />
<br />
&lt;VirtualHost *&gt;<br />
ServerName www2.example.com<br />
# ...<br />
SetEnv DJANGO_SETTINGS_MODULE mysite.other_settings<br />
&lt;/VirtualHost&gt;<br />
</pre>
</div>
<p>If you need to put two Django installations within the same <tt literal="">VirtualHost</tt>
(or in different <tt literal="">VirtualHost</tt> blocks that share the same server name),
you'll need to take a special precaution to ensure mod_python's cache doesn't
mess things up. Use the <tt literal="">PythonInterpreter</tt> directive to give different
<tt literal="">&lt;Location&gt;</tt> directives separate interpreters:</p>
<div>
<pre>&lt;VirtualHost *&gt;<br />
ServerName www.example.com<br />
# ...<br />
&lt;Location "/something"&gt;<br />
SetEnv DJANGO_SETTINGS_MODULE mysite.settings<br />
PythonInterpreter mysite<br />
&lt;/Location&gt;<br />
<br />
&lt;Location "/otherthing"&gt;<br />
SetEnv DJANGO_SETTINGS_MODULE mysite.other_settings<br />
PythonInterpreter othersite<br />
&lt;/Location&gt;<br />
&lt;/VirtualHost&gt;<br />
</pre>
</div>
<p>The values of <tt literal="">PythonInterpreter</tt> don't really matter, as long as they're
different between the two <tt literal="">Location</tt> blocks.</p>
</div>

<h2 id="running-a-development-server-with-mod-python">Running a development server with mod_python<a  title="Permalink to this headline">&#182;</a></h2>
<p>If you use mod_python for your development server, you can avoid the hassle of
having to restart the server each time you make code changes. Just set
<tt literal="">MaxRequestsPerChild 1</tt> in your <tt literal="">httpd.conf</tt> file to force Apache to reload
everything for each request. But don't do that on a production server, or we'll
revoke your Django privileges.</p>
<p>If you're the type of programmer who debugs using scattered <tt literal="">print</tt>
statements, note that <tt literal="">print</tt> statements have no effect in mod_python; they
don't appear in the Apache log, as one might expect. If you have the need to
print debugging information in a mod_python setup, either do this:</p>
<div>
<pre>assert False, the_value_i_want_to_see<br />
</pre>
</div>
<p>Or add the debugging information to the template of your page.</p>

<h2 id="id1">Serving media files<a  title="Permalink to this headline">&#182;</a></h2>
<p>Django doesn't serve media files itself; it leaves that job to whichever Web
server you choose.</p>
<p>We recommend using a separate Web server -- i.e., one that's not also running
Django -- for serving media. Here are some good choices:</p>
<ul>
    <li><a external="" >lighttpd</a></li>
    <li><a external="" >TUX</a></li>
    <li>A stripped-down version of <a external="" >Apache</a></li>
</ul>
<p>If, however, you have no option but to serve media files on the same Apache
<tt literal="">VirtualHost</tt> as Django, here's how you can turn off mod_python for a
particular part of the site:</p>
<div>
<pre>&lt;Location "/media"&gt;<br />
SetHandler None<br />
&lt;/Location&gt;<br />
</pre>
</div>
<p>Just change <tt literal="">Location</tt> to the root URL of your media files. You can also use
<tt literal="">&lt;LocationMatch&gt;</tt> to match a regular expression.</p>
<p>This example sets up Django at the site root but explicitly disables Django for
the <tt literal="">media</tt> subdirectory and any URL that ends with <tt literal="">.jpg</tt>, <tt literal="">.gif</tt> or
<tt literal="">.png</tt>:</p>
<div>
<pre>&lt;Location "/"&gt;<br />
SetHandler python-program<br />
PythonHandler django.core.handlers.modpython<br />
SetEnv DJANGO_SETTINGS_MODULE mysite.settings<br />
&lt;/Location&gt;<br />
<br />
&lt;Location "/media"&gt;<br />
SetHandler None<br />
&lt;/Location&gt;<br />

&lt;LocationMatch "".(jpg|gif|png)$"&gt;<br />
SetHandler None<br />

<p>Note that the Django development server automagically serves admin media files,

responsible for setting up Apache, or whichever media server you're using, to
serve the admin files.</p>
<p>The admin files live in (<tt literal="">django/contrib/admin/media</tt>) of the Django
distribution.</p>
<p>Here are two recommended approaches:</p>
<ol simple="">
    <li>Create a symbolic link to the admin media files from within your

project, some extra configuration is required. Create an extra file in your
project (or somewhere else) that contains something like the following:</p>
<div>
<pre>import os<br />
os.environ['PYTHON_EGG_CACHE'] = '/some/directory'<br />
</pre>
</div>
<p>Here, <tt literal="">/some/directory</tt> is a directory that the Apache webserver process can
write to. It will be used as the location for any unpacking of code the eggs
need to do.</p>
<p>Then you have to tell mod_python to import this file before doing anything
else. This is done using the <a external="" >PythonImport</a> directive to mod_python. You need
to ensure that you have specified the <tt literal="">PythonInterpreter</tt> directive to
mod_python as described <a internal="" >above</a> (you need to do this even if you aren't
serving multiple installations in this case). Then add the <tt literal="">PythonImport</tt>
line in the main server configuration (i.e., outside the <tt literal="">Location</tt> or
<tt literal="">VirtualHost</tt> sections). For example:</p>
<div>
<pre>PythonInterpreter my_django<br />
PythonImport /path/to/my/project/file.py my_django<br />
</pre>
</div>
<p>Note that you can use an absolute path here (or a normal dotted import path),
as described in the <a external="" >mod_python manual</a>. We use an absolute path in the
above example because if any Python path modifications are required to access
your project, they will not have been done at the time the <tt literal="">PythonImport</tt>
line is processed.</p>

<h2 id="error-handling">Error handling<a  title="Permalink to this headline">&#182;</a></h2>
<p>When you use Apache/mod_python, errors will be caught by Django -- in other
words, they won't propagate to the Apache level and won't appear in the Apache
<tt literal="">error_log</tt>.</p>
<p>The exception for this is if something is really wonky in your Django setup. In
that case, you'll see an "Internal Server Error" page in your browser and the
full Python traceback in your Apache <tt literal="">error_log</tt> file. The <tt literal="">error_log</tt>
traceback is spread over multiple lines. (Yes, this is ugly and rather hard to
read, but it's how mod_python does things.)</p>
</div>
<div   class="wmqeeuq"   id="s-if-you-get-a-segmentation-fault">
<h2 id="if-you-get-a-segmentation-fault">If you get a segmentation fault<a  title="Permalink to this headline">&#182;</a></h2>
<p>If Apache causes a segmentation fault, there are two probable causes, neither
of which has to do with Django itself.</p>
<ol simple="">
    <li>It may be because your Python code is importing the "pyexpat" module,
    which may conflict with the version embedded in Apache. For full
    information, see <a external="" >Expat Causing Apache Crash</a>.</li>
    <li>It may be because you're running mod_python and mod_php in the same
    Apache instance, with MySQL as your database backend. In some cases,
    this causes a known mod_python issue due to version conflicts in PHP and
    the Python MySQL backend. There's full information in the
    <a external="" >mod_python FAQ entry</a>.</li>
</ol>
<p>If you continue to have problems setting up mod_python, a good thing to do is
get a barebones mod_python site working, without the Django framework. This is
an easy way to isolate mod_python-specific problems. <a external="" >Getting mod_python Working</a>
details this procedure.</p>
<p>The next step should be to edit your test code and add an import of any
Django-specific code you're using -- your views, your models, your URLconf,
your RSS configuration, etc. Put these imports in your test handler function
and access your test URL in a browser. If this causes a crash, you've confirmed
it's the importing of Django code that causes the problem. Gradually reduce the
set of imports until it stops crashing, so as to find the specific module that
causes the problem. Drop down further into modules and look into their imports,
as necessary.</p>

<p><u><font color="#800080">�Q�，更新到最新的hibernate3.2</font></u><br />
</p>
3�?br />
<br />
�q�里以tomcat环境��Z���Q�其它WEB服务器如jboss,weblogic�{�是同一个道理�?br />
一、java.lang.OutOfMemoryError: PermGen space
<p>PermGen space的全�U�是Permanent Generation space,是指内存的永久保存区�?<br />
�q�块内存主要是被JVM存放Class和Meta信息�?Class在被Loader时就�?x��)被攑ֈ�PermGen space�?<br />
它和存放�c�d���?Instance)的Heap区域不同,GC(Garbage Collection)不会(x��)在主�E�序�q�行期对<br />
PermGen space�q�行清理�Q�所以如果你的应用中有很多CLASS的话,���很可能出现PermGen space错误,<br />
�q�种错误常见在web服务器对JSP�q�行pre compile的时候。如果你的WEB APP下都用了(ji��n)大量的第三方jar, 其大��?br />
���过�?ji��n)jvm默认的大��?4M)那么��׃��(x��)产生此错误信息了(ji��n)�?br />
解决�Ҏ(gu��)���Q?手动讄���MaxPermSize大小</p>
<p>修改TOMCAT_HOME/bin/catalina.sh<br />
�?#8220;echo "Using CATALINA_BASE:&nbsp;&nbsp; $CATALINA_BASE"&#8221;上面加入以下行：(x��)<br />
JAVA_OPTS="-server -XX:PermSize=64M -XX:MaxPermSize=128m<br />
������Q�将相同的第三方jar文�g�Uȝ��到tomcat/shared/lib目录下，�q�样可以辑ֈ�减少jar 文档重复占用内存的目的�?/p>
<p>二、java.lang.OutOfMemoryError: Java heap space<br />
Heap size 讄���<br />
JVM堆的讄���是指java�E�序�q�行�q�程中JVM可以调配使用的内存空间的讄���.JVM在启动的时候会(x��)自动讄���Heap size的��|��<br />
其初始空�?�?Xms)是物理内存的1/64�Q�最大空�?-Xmx)是物理内存的1/4。可以利用JVM提供�?Xmn -Xms -Xmx�{�选项�?br />
�q�行讄���。Heap size 的大���是Young Generation 和Tenured Generaion 之和�?br />
提示�Q�在JVM中如�?8�Q�的旉���是用于GC且可用的Heap size 不��2�Q�的时候将抛出此异�怿�息�?br />
提示�Q�Heap Size 最大不要超�q�可用物理内存的80�Q�，一般的要将-Xms�?Xmx选项讄���为相同，�?Xmn�?/4�?Xmx倹{�?<br />
解决�Ҏ(gu��)���Q�手动设�|�Heap size<br />
修改TOMCAT_HOME/bin/catalina.sh<br />
�?#8220;echo "Using CATALINA_BASE:&nbsp;&nbsp; $CATALINA_BASE"&#8221;上面加入以下行：(x��)<br />
JAVA_OPTS="-server -Xms800m -Xmx800m&nbsp;&nbsp; -XX:MaxNewSize=256m"</p>
<p>三、实例，以下�l�出1G内存环境下java jvm 的参数设�|�参考：(x��)</p>
<p>JAVA_OPTS="-server -Xms800m -Xmx800m&nbsp; -XX:PermSize=64M -XX:MaxNewSize=256m -XX:MaxPermSize=128m -Djava.awt.headless=true "</p>

<h2><a name="s2">What is mod_jk?</a></h2>
<p>mod_jk is a replacement to the elderly mod_jserv. It is a completely new
Tomcat-Apache plug-in that handles the communication between Tomcat and Apache.</p>
<hr />
<h2><a name="s3">Why mod_jk?</a></h2>
<p>Several reasons: </p>
<ul>
    <li><strong>mod_jserv was too complex</strong>. Because it was ported from Apache/JServ, it
    brought with it lots of JServ specific bits that aren't needed by Apache.
    </li>
    <li><strong>mod_jserv supported only Apache</strong>. Tomcat supports many web servers
    through a compatibility layer named the jk library. Supporting two different
    modes of work became problematic in terms of support, documentation and bug
    fixes. mod_jk should fix that.</li>
    <li>The layered approach provided
    by the jk library makes it easier to support both <strong>Apache1.3.x <em>and</em>
    Apache2.xx.</strong></li>
    <li><strong>Better support for SSL</strong>. mod_jserv couldn't reliably identify whether a
    request was made via HTTP or HTTPS. mod_jk can, using the newer Ajpv13 protocol.</li>

<h2><a name="s4">What does it mean to me?</a></h2>
<p>You will need to get to know a new simplified configuration mechanism. The
advantage is that learning this mechanism will give you a head start if you
want to deploy Tomcat on Apache and other web servers, such as Microsoft's
Internet Information Server (IIS) and the iPlanet Enterprise Web Server.</p>
<hr />
<h2><a name="s5">Definitions and Terminology</a></h2>
<p>In this document I am going to use a few terms, so let's define them:</p>

            <p>Term</p>

            </td>
            <td>
            <p>A worker is a tomcat instance that is running to serve
            servlet requests coming from the web server. In most cases there is only a
            single worker (the one and only tomcat process) but sometimes you will run
            multiple workers to achieve load balancing or site partitioning. Each worker
            is identified to the web server by the host were it is located, the port
            where it listens and the communication protocol used to exchange messages.</p>

            </td>
            <td>
            <p>This is a special worker. Instead of working with a Tomcat
            process residing on another process, the web server opens a JVM and executes
            Tomcat inside the web server process address space. Our discussion in this
            document is not going to get into this special worker.</p>

            This is the web server plug-in, and in our case the web server plug-in is
            mod_jk. The redirector usually comes in the shape of a DLL or shared object
            module that you plug into the web server.</p>

        </tr>
    </tbody>

<hr />
<h2><a name="s6">Obtaining mod_jk</a></h2>
<p>mod_jk can be obtained in two formats - binary and source.&nbsp; Depending on
the platform you are running your web server on, a binary version of mod_jk may
be available.&nbsp; It is recommended to use the binary version if one is
available.&nbsp; If the binary is not available, follow the instructions for
building mod_jk from source.&nbsp; Notes at the end of this section offer
recommendations for specific platforms. </p>
<h3><a name="s61">mod_jk Binaries</a></h3>
<p>Binaries for mod_jk are available for several platforms in the same area as
the Tomcat Binary Release.&nbsp; The binaries are located in subdirectories by platform.&nbsp; For some
platforms, such as Windows, this is the typical way of obtaining mod_jk since
most Windows systems do not have C compilers.&nbsp; For others, the binary
distribution of mod_jk offers simpler installation. </p>
<p>For example, the Tomcat 3.3 M1 Release at <a >http://jakarta.apache.org/builds/jakarta-tomcat/release/v3.3-m1/bin/</a>
contains the following: </p>
<table border="1" bordercolor="#000000" cellpadding="2" cellspacing="0" width="600">
    <tbody>
        <tr>
            <td width="15%">linux/i386/</td>
            <td width="85%">Contains mod_jk.so for Apache 1.3 for the standard API as
            well as EAPI and mod_jk.so for Apache 2.0</td>
        </tr>
        <tr>
            <td width="15%">netware/</td>
            <td width="85%">Contains the mod_jk.nlm and nsapi.nlm</td>
        </tr>
        <tr>
            <td width="15%">win32/</td>
            <td width="85%">Contains the mod_jk.dll for Windows as well as other useful
            binaries.</td>
        </tr>
    </tbody>
</table>
<p>Check the site for the latest binaries.</p>
<p>Note: The version of mod_jk is not dependent on the version of Tomcat.&nbsp;
The Tomcat 3.3 distribution of mod_jk will function correctly with other 3.x
versions of Tomcat, such as Tomcat 3.2.1.</p>
<h3><a name="s62">Building mod_jk</a></h3>
<p>mod_jk is available in source distribution for all Windows and most Unix
platforms.&nbsp; The source for mod_jk is included in the Binary Distribution of
Tomcat in the TOMCAT_HOME/native/mod_jk/ directory.&nbsp; This directory is
organized by Web Server name and version.&nbsp; Each directory contains the
source as well as the appropriate build scripts, make files, or project files. </p>
<h3><a name="s63">Building mod_jk for NT</a></h3>
<p>The redirector was developed using Visual C++ version 6.0, so having this
environment is a prerequisite if you want to perform a custom build.</p>
<p>The steps that you need to take are: </p>
<ol>
    <li>Change directory to the apache1.3 or apache2.0 source directory depending
    on your version of Apache. </li>
    <li>Set an APACHE1_HOME environment variable which points to where your Apache is
    installed.</li>
    <li>Execute the following
    command:<br />
    <br />
    <tt>MSDEV mod_jk.dsp /MAKE ALL</tt><br />
    <br />
    If msdev is not in your path, enter the full path to msdev.exe. Also, ApacheCore.lib
    is expected to exist in the APACHE1_HOME"src"CoreD and APACHE1_HOME"src"CoreR
    directories before linking will succeed. You will need to build enough of the
    Apache source to create these libraries.</li>
    <li>Copy mod_jk.dll to Apache's modules directory.</li>
</ol>
<p>This will build both release and debug versions of the redirector plug-in (mod_jk). </p>
<p>An alternative will be to open <tt>mod_jk.dsp</tt> in msdev and build it using the build
menu.</p>
<h3><a name="s64">Building mod_jk for Unix</a></h3>
<h4> Apache</h4>
<ol>
    <li>Make sure your Apache has DSO support. You can check this
    with <tt>$APACHE_HOME/bin/httpd -l</tt>. If you see
    "mod_so.c" in the output, DSO support is available. If it's
    missing, you may have to recompile or reinstall Apache.</li>
    <li>Find out whether your Apache has EAPI support. If you
    compiled it yourself from source, EAPI is probably not compiled
    in, unless you added it yourself (perhaps with mod_ssl). You
    need to build mod_jk.so with or without EAPI to match your
    Apache configuration. If you install a mismatched mod_jk.so,
    <tt>$APACHE_HOME/bin/apachectl configtest</tt> will warn
    you.</li>
    <li>Make sure you have Perl 5 installed. The <tt>apxs</tt>
    script used to build the module is written in Perl.
    </li>
    <li>Change directory to <tt>TOMCAT_HOME/native/mod_jk/apache1.3</tt> (or
    <tt>apache2.0</tt>).
    </li>
    <li>
    <p>Build mod_jk.so. Following are three techniques you can try,
    in order of simplicity:</p>
    <ol>
        <li>Run the build script for your platform.&nbsp; If a build script is
        not available for your platform, you may be able to build mod_jk using <tt>./build-unix.sh</tt>. This script will set some variables, call
        <tt>apxs</tt> as below, and try to copy mod_jk.so to
        $APACHE_HOME/libexec. If it fails, you need to do
        the following manually:
        <ul>
            <li>set JAVA_HOME in your shell, e.g. "<tt>set
            JAVA_HOME=/usr/local/jdk1.2.2; export
            JAVA_HOME</tt>"</li>
            <li>set APACHE_HOME in your shell, e.g.
            "<tt>set APACHE_HOME=/usr/local/apache;
            export APACHE_HOME</tt>"</li>
            <li>uncomment the following line in the
            <tt>build-unix.sh</tt> file,
            replacing "linux" with the name of your
            platform as specified in the
            Java include directory for your installation
            <blockquote><tt># JAVA_INCLUDE="-I
            ${JAVA_HOME}/include -I
            ${JAVA_HOME}/include/linux"</tt></blockquote>
            </li>
        </ul>
        </li>
        <li>If build-unix.sh fails, you may have better luck
        with the Makefiles in the same directory, e.g.
        "<tt>make -f Makefile.linux mod_jk.so</tt>"
        </li>
        <li>
        <p>Finally, you can try to build it manually. Run the
        <tt>apxs</tt> command that came with your apache
        distribution (hint: look in /usr/local/apache/bin,
        /usr/sbin, or wherever you installed apache). Type the
        command all on one line.</p>
        <hr />
        <p>For Linux:</p>
        <blockquote><tt>apxs -o mod_jk.so -I../jk
        -I/usr/local/jdk/include -I/usr/local/jdk/include/linux
        -c *.c ../jk/*.c</tt></blockquote>
        <p>Your build may fail because the object files from
        the <tt>../jk</tt> directory have been compiled to the
        current directory, rather than their source directory.
        Running <tt>gcc -shared -o mod_jk.so *.o</tt>
        should finish the build.</p>
        <hr />
        <p>For Solaris:</p>
        <p>Use the <tt>build-solaris.sh</tt> script as follows:</p>
        <blockquote><tt># sh build-solaris.sh</tt></blockquote>
        <p>This will build and install mod_jk.so in your apache/libexec
        directory.&nbsp; This script contains settings for your Java and Apache
        home locations.&nbsp; Make sure that these are set according to your
        installation.&nbsp; The default settings are <tt>JAVA_HOME=/usr/java</tt> and
        <tt>APACHE_HOME=/usr/local/apache</tt>.&nbsp; If your installation is different,
        you will need to edit the <tt>build-solaris.sh</tt> script and change these
        values appropriately.</p>
        <p>See <tt>README.solaris</tt> located in <tt>TOMCAT_HOME/native/mod_jk/apache1.3</tt>
        for more information.</p>
        <p>If the build script does not work, you can also build mod_jk as
        follows:</p>
        <blockquote><tt>$APACHE_HOME/bin/apxs -o mod_jk.so -DSOLARIS -I../jk -I/usr/java/include
        -I/usr/java/include/solaris -c *.c ../jk/*.c</tt></blockquote>
        <p>On some systems, this will build the module
        correctly, but will fail at runtime with a
        "<tt>symbol "fdatasync" not found</tt>". To
        fix, add <tt>-lposix4</tt> just before the
        <tt>-c</tt> in the above command.</p>
        <hr />
        <p>For HP-UX 11.00:</p>
        <p>Use the <tt>build-hpux.sh</tt> script as follows:</p>
        <blockquote><tt># sh build-hpux.sh</tt></blockquote>
        <p>This will build and install mod_jk.so in your apache/libexec
        directory.&nbsp; This script contains settings for your Java and Apache
        home locations.&nbsp; Make sure that these are set according to your
        installation.&nbsp; The default settings are <tt>JAVA_HOME=/opt/java1.3</tt> and
        <tt>APACHE_HOME=/usr/local/apache</tt>.&nbsp; If your installation is different,
        you will need to edit the <tt>build-hpux.sh</tt> script and change these
        values appropriately.</p>
        <p>Also note that there are two HP-UX build scripts.&nbsp; One script
        was written to build mod_jk without JNI support using GNU GCC.&nbsp; The
        other script builds mod_jk with JNI support, however, this script
        requires the HP ANSI C Compiler (not the stripped down C compiler
        included with HP-UX to rebuild the kernel).&nbsp; The HP Compiler is
        required because the dlopen() and related shared libraries are only
        available for 64-bit applications and reliable 64-bit compilation is not
        available with the current version of GCC.</p>
        <p>The <tt>build-hpux.sh</tt> script should also work for HP-UX 10.00.</p>
        <p>See <tt>README.hpux</tt> located in <tt>TOMCAT_HOME/native/mod_jk/apache1.3</tt>
        for more information.</p>
        <hr />
        <p>For other Unixes (including FreeBSD):</p>
        <p>You may need to replace fdatasync() with fsync() in jk_util.c.</p>
        <p>The <tt>build-hpux-cc.sh</tt> script should be modifiable for IRIX and AIX.&nbsp;
        Edit the script and change the APACHE_HOME and JAVA_HOME locations as
        required.</p>
        <hr />
        <p>If you are using EAPI, try adding
        <tt>-DEAPI</tt> to the apxs command after
        <tt>mod_jk.so</tt>.</p>
        <p>If apxs fails with <code>apxs:Break: Command failed
        with rc=255</code>, it may have been damaged by
        mod_ssl. Search for:</p>
        <pre>my $CFG_LD_SHLIB      = q();          # substituted via Makefile.tmpl<br />
        my $CFG_LDFLAGS_SHLIB = q(); # substituted via Makefile.tmpl<br />
        </pre>
        <p>and change to:</p>
        <pre>my $CFG_LD_SHLIB      = q(ld);          # substituted via Makefile.tmpl<br />
        my $CFG_LDFLAGS_SHLIB = q(-G); # substituted via Makefile.tmpl<br />
        </pre>
        <p>If you've installed Java in another directory,
        adjust accordingly.</p>
        <p>For other Unixes you should be able to work it out,
        but remember that <strong>the order of the arguments to
        <tt>apxs</tt> is important!</strong>.</p>
        </li>
    </ol>
    </li>
    <li>Now, copy the mod_jk library.&nbsp; <tt># cp mod_jk.so $APACHE_HOME/libexec</tt>.  (Note that
    the build scripts attempt to do this, but you may have to
    <tt>su</tt> first.)</li>
</ol>
<h4>Other Webservers</h4>
<p>There are several Makefiles in the other directories under the <tt>TOMCAT_HOME/native/mod_jk/</tt>
directory.&nbsp; You should also check the Tomcat documentation for specific
information related to other web servers.</p>
<hr />
<h2><a name="s7">Configuring Apache</a></h2>
<p>This section details the configuration that is required for the Apache Web
Server to support mod_jk.</p>
<h3><a name="s71">Removing mod_jserv directives</a></h3>
<p>
If you've previously configured Apache to use mod_jserv, remove any <tt>ApJServMount</tt> directives from your httpd.conf. If you're including <tt>tomcat-apache.conf</tt> or <tt>tomcat.conf</tt>, you'll want to remove them as well - they are specific to
mod_jserv.&nbsp; The mod_jserv configuration directives are not compatible with
mod_jk!
</p>
<h3><a name="s72">Configure Apache to use mod_jk</a></h3>
<div>
<p>The simplest way to configure Apache to use mod_jk is to turn on the Apache
auto-configure setting in Tomcat and put the following include directive at the
end of your Apache httpd.conf file (make sure you replace TOMCAT_HOME with the
correct path for your Tomcat installation:</p>
<p><tt>Include TOMCAT_HOME/conf/jk/mod_jk.conf-auto</tt></p>
<p>Example:</p>
<p><tt>Include /usr/local/jakarta-tomcat/conf/jk/mod_jk.conf-auto</tt></p>
<p>This will tell Apache to use directives in the mod_jk.conf-auto file
in the Apache configuration.&nbsp; This file is created by enabling the Apache
auto-configuration as described in the configuring Tomcat section below [<a >Configuring
Tomcat</a>].</p>
<p><strong>NOTE:&nbsp; If you plan to use the Tomcat-Apache auto-configuration, skip
the rest of this section and continue with the <a >Configuring Tomcat</a>
section.</strong></p>
<p>Custom configurations can be created by enabling the auto-configuration and
copying the <tt>TOMCAT_HOME/conf/jk/mod_jk.conf-auto</tt> file to your own
configuration file, such as <tt>TOMCAT_HOME/conf/jk/mod_jk.conf-local</tt>.</p>
<p>The basic configuration is as follows:</p>
<ul>
    <li>You will need to instruct Apache to load Tomcat. This can be done with
    Apache's <tt>LoadModule</tt> and <tt>AddModule</tt> configuration directives.</li>
    <li>You must inform mod_jk the location of your <tt>workers.properties</tt> file.
    Use mod_jk's <tt>JkWorkersFile</tt> configuration directive.</li>
    <li>You should specify a location where mod_jk is going to place its log file
    and a log level to be used. Use the <tt>JkLogFile</tt> and <tt>JkLogLevel</tt>
    configuration directives. Possible log levels are <em>debug</em>, <em>info</em>,
    <em>error</em> and <em>emerg</em>, but <em>info</em> should be your default
    selection.</li>
    <li>The directive <tt>JkLogStampFormat</tt> will configure the date/time format
    found on mod_jk logfile. Using <tt>strftime()</tt> format string it's set by
    default to "[%a %b %d %H:%M:%S %Y] "</li>
</ul>
A simple example would be to include the following lines in your <tt>httpd.conf</tt> file:
<blockquote>
<pre>LoadModule    jk_module  libexec/mod_jk.so<br />
AddModule     mod_jk.c<br />
JkWorkersFile /usr/local/jakarta-tomcat/conf/workers.properties<br />
JkLogFile     /usr/local/apache/logs/mod_jk.log<br />
JkLogLevel    info<br />
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "<br />
</pre>
</blockquote>
</div>
<h3><a name="s73">Assigning URLs to Tomcat</a></h3>
<div>
<p>If you have created a custom or local version of <tt>mod_jk.conf-local</tt>
as noted above, you can change settings such as the workers or URL prefix.</p>
<p>Use mod_jk's JkMount directive to assign specific URLs to Tomcat. In general
the structure of a JkMount directive is:</p>
<pre>JkMount <em>&lt;URL prefix&gt;</em> <em>&lt;Worker name&gt;</em>
</pre>
<p>For example the following directives will send all requests ending in
<tt>.jsp</tt> or beginning with <tt>/servlet</tt> to the "<tt>ajp13</tt>" worker,
but jsp requests to files located in /otherworker will go to "<tt>remoteworker</tt>".
</p>
<blockquote>
<pre>JkMount /*.jsp ajp13<br />
JkMount /servlet/* ajp13<br />
JkMount /otherworker/*.jsp remoteworker<br />
</pre>
</blockquote>
You  can use the <tt>JkMount</tt> directive at the top level or inside <tt>&lt;VirtualHost&gt;</tt>
sections of your httpd.conf file.
</div>
<hr />
<h2><a name="s8">Configuring Tomcat</a></h2>
<h3><a name="s81">Enabling Tomcat's Apache Auto-Config</a></h3>
<div>
<p>
In most simple cases Tomcat can generate the needed Apache configuration. You
can configure Tomcat so that when it starts up it will automatically generate
a configuration file for Apache to use mod_jk.
Most of the time you don't need to do anything but
include this file (appending <tt>"Include TOMCAT_HOME/conf/jk/mod_jk.conf-auto"</tt>)
in your httpd.conf, as shown in the previous section (<a >Configuring
Apache</a>).
</p>
<p>To configure Tomcat to generate the Apache auto-configuration add the following block to your <tt>TOMCAT_HOME/conf/server.xml</tt>  file after <tt>&lt;AutoWebApp ... /&gt;</tt>.
</p>
<blockquote>
<pre>&lt;ApacheConfig /&gt;<br />
</pre>
</blockquote>
<p>
That's it, you can
now start Tomcat and Apache and access Tomcat from the Apache server.
</p>
<p>Note: Settings for mod_jk auto-configuration is new in Tomcat 3.3.&nbsp;
Older versions of Tomcat create the auto-config file without a directive in
server.xml.&nbsp; The new directive in Tomcat 3.3 allows for additional
configuration options as detailed later in this section.&nbsp; For older
versions of Tomcat, refere to the documentation that came with that version.
</p>
<p>
If you have special needs, for example mounting
URL prefixes that are not the default, you can use this file as a base for your
customized configuration and save the results in another file. If you manage
the Apache configuration yourself you'll need to update it whenever you add a
new context.
</p>
<p>Note that you must restart tomcat and apache after adding a new
context; Apache doesn't support configuration changes without a restart. Also
the file <tt>TOMCAT_HOME/conf/jk/mod_jk.conf-auto</tt> is generated when
tomcat starts, so you'll need to start Tomcat before Apache. Tomcat will
overwrite <tt>TOMCAT_HOME/conf/jk/mod_jk.conf-auto</tt> each startup so
customized configuration should be kept elsewhere.&nbsp; For example, copy&nbsp;
<tt>TOMCAT_HOME/conf/jk/mod_jk.conf-auto</tt> to <tt>TOMCAT_HOME/conf/jk/mod_jk.conf-local
</tt>before making changes.&nbsp; You'll need to startup Tomcat once to generate
this file with your configuration for the first time.
</p>
<p>It is also possible to specify the location of the auto generated files by
setting options in the &lt;ApacheConfig /&gt; block.&nbsp; The following details
the syntax:
</p>
<blockquote>
<pre>&lt; ContextManager ... &gt;<br />
...<br />
&lt;ApacheConfig <em>options</em> /&gt;<br />
...<br />
&lt; /ContextManager &gt;<br />
</pre>

<ul>
    <li><strong>confighome</strong> - default parent directory for the following paths. If
    not set, this defaults to TOMCAT_HOME. Ignored whenever any of the following
    paths is absolute.

    <li><strong>jservconfig</strong> - path to write apache jserv conf file to. If not set,

    not set, defaults to "conf/jk/workers.properties".
    </li>
    <li><strong>modjserv</strong> - path to Apache JServ plugin module file. If not set,
    defaults to "modules/ApacheModuleJServ.dll" on windows,
    "modules/Jserv.nlm" on netware, and "libexec/mod_jserv.so"
    everywhere else.
    </li>
    <li><strong>modjk</strong> - path to Apache mod_jk plugin file. If not set, defaults to

    netware, and "libexec/mod_jk.so" everywhere else.
    </li>
    <li><strong>jklog</strong> - path to log file to be used by mod_jk.</li>
</ul>
<p>
&nbsp;Example:
</p>
<blockquote>
<pre>...<br />
<br />
&lt;AutoWebApp dir="webapps" host="DEFAULT" /&gt;<br />
<br />
&lt;ApacheConfig confighome="/home/mydir" /&gt;<br />
<br />
...</pre>
</blockquote>
</div>
<h3><a name="s82">(Optional) Configuring Tomcat to use the Ajpv13 protocol</a></h3>
<div>
mod_jk can use either the original Ajpv12 protocol or the newer Ajpv13 protocol.
Both protocols are enabled by default. The "Ajp13" Connection Handler in Tomcat will
give you the benefit of a faster protocol and the ability to identify requests made via HTTPS.<br />
<br />
The following block enables Ajpv13 in your <tt>TOMCAT_HOME/conf/server.xml</tt> file.
<blockquote>
<pre>&lt;RequestInterceptor<br />
className="org.apache.tomcat.modules.server.Ajp13Interceptor"<br />
port="8009"/&gt;<br />
</pre>
</blockquote>
<p>The <tt>server.xml</tt> file already has a block similar to this for
Ajp12 connections on port 8007 (as delivered by mod_jserv). Even if you
think you're only using Ajp13, you probably don't want to delete this
connector -- it's required to shut down Tomcat.</p>
</div>
<h3><a name="s83">(Optional) Defining "workers"</a></h3>
<h4>Configuring workers manually.</h4>
<div>
<p>
Workers are configured using the file <tt>TOMCAT_HOME/conf/jk/workers.properties</tt>.
There is a great deal of information in the
<a >workers.properties howto</a> document, and you
should really look at that first. If you're in a hurry however, you can probably get away
with editing the file <tt>workers.properties</tt> and setting the <tt>workers.tomcat_home</tt>, <tt>workers.java_home</tt> and <tt>ps</tt> variables to the correct values for your system.
</p>
</div>
<hr />
<h2><a name="s9">Example Configuration</a></h2>
Here's an example configuration which probably reflects many real-world setups. A site
is using Tomcat and Apache with two virtual hosts (one of them using HTTPS as well, which
we're assuming is being handled by mod_ssl).
<br />
<br />
URLs ending in .jsp and beginning with /servlet are handled by Tomcat, the rest are
handled by Apache. The files for each Host are server out of /web/host1 and /web/host2
respectively.<br />
<br />
The example are over-simplified and incomplete but should get you started. Also note the
virtual host setup is new in Tomcat 3.2 - <em>this example won't work with Tomcat 3.1</em>.<br />

<hr />
<h2><a name="s10">Troubleshooting and F.A.Q.s</a></h2>
<h3>Q. Where can I get help/support for mod_jk?</h3>
A. The primary mechanism for support is through the Tomcat Documentation
included in the TOMCAT_HOME/doc directory.&nbsp; These documents are viewable
via browser through Tomcat <a href="http://localhost:8080/doc/index.html">http://localhost:8080/doc/index.html</a>.&nbsp;
Documentation is also available on the Apache Jakarta web site for Tomcat at <a >http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/index.html</a>.
<p>For additional help, the best resource is the Tomcat Users Discussion
list.&nbsp; You should start by searching the mail list archives located at <a href="http:///">http://mikal.org/interests/java/tomcat/index.html</a>
before you post questions to the list.&nbsp; If you are unable to locate the
answer to your question in the archive, you can post questions about Tomcat or
mod_jk to the user list for assistance.&nbsp; Make sure that you include the
version of Apache and Tomcat that you are using as well as the platform you are
running on. <a href="http:///">http://jakarta.apache.org/site/mail.html</a></p>
<h3>Q. I can't find mod_jk anywhere. Where is it?</h3>
A. Starting with Tomcat 3.3, the source for mod_jk is included in the native/mod_jk
directory.&nbsp; You can also download the Source Distribution of Tomcat to
obtain the source for mod_jk, which is how it was obtained in versions prior to
Tomcat 3.3. The Binary Distributions of mod_jk are available at the same
location as the Binary Distribution of Tomcat.&nbsp; The mod_jk binaries are
located in subdirectories by platform.
But in May 2001, the jakarta-tomcat-connectors was started and you'll find here
up to date featured mod_jk (ie: new protocols AJP14/WARP)
<h3>Q. Which protocol should I use? Ajp12 or Ajp13?</h3>
A. Ajp13 is a newer protocol, it's faster, and it works better with SSL. You almost
certainly want to use it. There is more information in the
<a >workers.properties howto</a> document.
<h3>Q. Whenever I restart Tomcat, Apache locks up!</h3>
A. The Ajp13 protocol keeps an open socket between Tomcat and Apache. The latest
release of mod_jk (the one found since Tomcat 3.3-m2 and J-T-C) handle the network failure.
But with previous release of mod_jk, you may have to restart Apache as well.
<h3>Q. Why did exist two files mod_jk.so (-eapi ad -noeapi) in download dir for Linux ?</h3>
A. Many versions of Apache use of modified API, known at Extended API. For example,
Apache using mod_ssl or Apache present in certains recent Linux distributions.
So if you got such 'Extended Apache', you need to use mod_jk.so-eapi, or use
mod_jk.so-noeapi for standard Apache. It's wise to avoid using EAPI modules on STD API Apache or to use standard
API modules on EAPI Apache. Allways be sure to have the mod_jk.so for your version of Apache
<h3>Q. What's that message about 'garbled DSO ?'</h3>
A. It's related to Apache EAPI, the message 'mod_jk.so is garbled - perhaps this is not an Apache module DSO ?'
just told you are trying to install a mod_jk.so DSO module that was compiled on an Apache using EAPI,
like apache-mod_ssl or apache from Redhat distro 6.2/7.0 but your system use the standard apache
with normal API.
<h3>Q. And the message about 'module might crash under EAPI! '</h3>
A. Also related to EAPI, the message '[warn] Loaded DSO /usr/lib/apache/mod_jk.so uses plain Apache 1.3 API,
this module might crash under EAPI! (please recompile it with -DEAPI)', the mod_jk.so was compiled under normal
Apache with standard API and you try to install the module on an Apache using EAPI.
<h3>Q. Where can I get more information?</h3>
A. The <a >workers.properties howto</a> document has
considerably more in-depth information than this one, and is worth a look. You could
also try searching the mailing list archives for "mod_jk" or look at the source.
<h3>Q.
APXS is getting an error during the build of mod_jk, like rc=0 or rc=255.&nbsp;
I tried all of the steps in the build section, what do I do now?</h3>
A. APXS is a Perl script that is created when you build the Apache web server
from source.&nbsp; Chances are that if you are getting these errors and you
obtained Apache as a binary distribution, that APXS is not configured correctly
for your system.&nbsp; Your best bet is to get the Apache source from <a >http://httpd.apache.org</a>
and build it yourself.&nbsp; Use the following for a basic build (read the
Apache docs for other options):
<blockquote>
<pre># cd /usr/local/src<br />
# gzip -dc apache_1.3.19.tar.gz|tar xvf -<br />
# cd apache_1.3.19<br />
# ./configure --prefix=/usr/local/apache "<br />
--enable-module=most "<br />
--enable-shared=max<br />
# make<br />
# make install</pre>
</blockquote>
<p>Note: The above steps assume that you downloaded the Apache source and placed
it in your /usr/local/src directory.</p>

<p>3.	无缝的升�U�应用程�?/p>

三点对一�?web �|�站来说是非�怹�重要的，我们希望我们的网站不仅是速度快，而且要稳定，不能因�ؓ(f��)某个 Tomcat
宕机或者是升��E�序��D��用户讉K��不了(ji��n)�Q�而能完成�q�几个功能的、最好的 HTTP 服务器也���只�?apache �?http server �?ji��n)，它�?
tomcat 的结合是最紧密和可靠的�?/p>
<p>接下来我们介�l�三�U�方法将 apache �?tomcat 整合在一赗��?/p>
<p><a name="N1005F">JK</a></p>
<p>�q�是最常见的方式，你可以在�|�上扑ֈ�很多关于配置JK的网��，当然最全的�q�是其官�Ҏ(gu��)��提供的文档。JK 本��n有两个版本分别是 1 �?2�Q�目�?1 最新的版本�?1.2.19�Q�而版�?2 早已�l�废弃了(ji��n)�Q�以后不再有新版本的推出�?ji��n)，所以徏议你采用版本 1�?/p>
<p>JK
是通过 AJP 协议�?Tomcat 服务器进行通讯的，Tomcat 默认�?AJP Connector 的端口是 8009。JK
本��n提供�?ji��n)一个监控以�?qi��ng)管理的���?jkstatus�Q�通过 jkstatus 可以监控 JK 目前的工作状态以�?qi��ng)对�?tomcat

<br />
<p>�?
�q�个图中我们可以看到当前JK配了(ji��n)两个�q�接分别�?8109 �?8209 端口上，目前 s2 �q�个�q�接是停止状态，�?s1
�q�个�q�接自上�ơ重启后已经处理�?47 万多个请求，���量辑ֈ� 6.2 �?G�Q�最大的�q�发数有 13 �{�等。我们也可以利用 jkstatus
的管理功能来切换 JK ��C��同的 Tomcat 上，例如��?s2 启用�Q��ƈ停用
s1�Q�这个在更新应用�E�序的时候非常有用，而且整个切换�q�程对用��h��说是透明的，也就辑ֈ��?ji��n)无�~�升�U�的目的。关�?JK
的配�|�文章网上已�l�非常多�?ji��n)，�q�里我们不再详细的介�l�整个配�|�过�E�，但我要讲一下配�|�的思�\�Q�只要明白了(ji��n)配置的思�\�Q�JK ���是一个非常灵�zȝ���l��g�?/p>
<p>JK 的配�|�最关键的有三个文�g�Q�分别是 </p>
<p>
<strong>httpd.conf </strong>
<br />
Apache 服务器的配置文�g�Q�用来加�?JK 模块以及(qi��ng)指定 JK 配置文�g信息</p>
<p>
<strong>workers.properties</strong>
<br />
�?Tomcat 服务器的�q�接定义文�g</p>
<p>
<strong>uriworkermap.properties</strong>
<br />
URI 映射文�g�Q�用来指定哪�?URL �?Tomcat 处理�Q�你也可以直接在 httpd.conf 中配�|�这�?URI�Q�但是独立这些配�|�的好处�?JK 模块�?x��)定期更新该文�g的内容，使得我们修改配置的时候无需重新启动 Apache 服务器�?/p>
<p>其中�W�二、三个配�|�文件名都可以自定义。下面是一个典型的 httpd.conf �?JK 的配�|?/p>
