TOMCAT调优

paulwong — Tue, 06 Jan 2015 09:40:00 GMT

安装AB

rpm -ivh http://repo.webtatic.com/yum/centos/5/`uname -i`/webtatic-release-5-0.noarch.rpm
yum install httpd-tools
使用AB

ab -r -n 100000 -c 10000 http://10.120.151.223:8080/
需�?r�Q�则在收到SOCKET错误的时候不会退�?br />�q�段的意思是发�?00000个请求，其中�q�发�?0000�?/div>
修改LINUX能打开的文件的最大数

2�?nbsp; 修改目标
我们的目标是�Q�让每一个用��L��录系�l�后�pȝ��打开的最大文件数都是我们讑֮�好的�?br /> 但我�q�里不得不说的是�Q�非帔R��憾，�|�上很多�q�方面关于ulimit讄��修改资源限制的文章，但没一��文章管用�?br /> 把这个目标分解�ؓ两个目标�Q?br />
2.1、设�|�对root用户��d��pȝ��生效
�q�个目标可以实现��h��不难

2.2、设�|�对所有用��L��?br /> �q�个��非帔R��烦了�Q�弄不好�q�会把你的系�l�给整坏�Q�因��重编译Linux的内核才行！
所以权衡之下，我只实现了第一个目标，因�ؓ�W�二个目标的风险太大�Q�我惛_��果我之前知道�q�点�Q�那么我在装�pȝ��的时候我会先做这个处理，但现在我觉得已经晚了�?br />
3�?nbsp; 修改的地�?br />
3.1、修�?etc/security/limits.conf
通过 vi /etc/security/limits.conf修改其内容，在文件最后加入（数��g��可以自己定义�Q�：
* soft nofile = 65536
* hard nofile = 65536
root soft nofile 65536
root hard nofile 65536
* 表示该配�|�对所有用户均有效,root用户要特别加两行�?br />
3.2、修�?etc/profile
通过vi /etc/profile修改�Q�在最后加入以下内�?br /> ulimit -n 65536
然后重新��d��卛_��生效了�?br /> 说明�Q?br /> 其实只修�?etc/profile��可以生效了�Q�但我还是徏议把/etc/security/limits.conf也修改一下�?br /> 最后强调的是，你如果要使得修改�Ҏ��有用户都生效�Q�那么现在看来你只能重新�~�译Linux的内核才行�?/div>
安装APR�Q�参考：http://jmchung.github.io/blog/2013/09/06/centos-installing-apache-portable-runtime-apr-for-tomcat/
$ wget http://apache.fayea.com//apr/apr-1.5.1.tar.gz

$ cd tomcat-native-x.y.z-src/jni/native
$ ./configure --with-apr=/usr/local/apr --with-ssl=/usr/lib64/openssl
$ make install
修改server.xml
<Connector port="8080" protocol="org.apache.coyote.http11.Http11AprProtocol"
        URIEncoding="UTF-8"
              enableLookups="false"

启用TOMCAT的SSL

paulwong — Mon, 14 Oct 2013 00:02:00 GMT

本教�E��?JDK 6 �?Tomcat 7�Q�其他版本类伹{�?br />
基本步骤�Q?br />
使用 java 创徏一�?keystore 文�g
配置 Tomcat 以��用该 keystore 文�g
��试
配置应用以便使用 SSL �Q�例�?https://localhost:8443/yourApp
1. 创徏 keystore 文�g

执行 keytool -genkey -alias tomcat -keyalg RSA �l�果如下

loiane:bin loiane$ keytool -genkey -alias tomcat -keyalg RSA
Enter keystore password:  password
Re-enter new password: password
What is your first and last name?
  [Unknown]:  Loiane Groner
What is the name of your organizational unit?
  [Unknown]:  home
What is the name of your organization?
  [Unknown]:  home
What is the name of your City or Locality?
  [Unknown]:  Sao Paulo
What is the name of your State or Province?
  [Unknown]:  SP
What is the two-letter country code for this unit?
  [Unknown]:  BR
Is CN=Loiane Groner, OU=home, O=home, L=Sao Paulo, ST=SP, C=BR correct?
  [no]:  y

Enter key password for
    (RETURN if same as keystore password):  password
Re-enter new password: password

�q�样��在用户的主目录下创��Z��一�?.keystore 文�g

2. 配置 Tomcat 以��?keystore 文�g

打开 server.xml 扑ֈ�下面被注释的�q�段

�q�掉注释�Q��ƈ��内�Ҏ��?br />

3. ��试

启动 Tomcat �q�访�?https://localhost:8443. 你将看到 Tomcat 默认的首��c�?br />
需要注意的是，如果你访问默认的 8080 端口�Q�还是有效的�?br />
4. 配置应用使用 SSL

打开应用�?web.xml 文�g�Q�增加配�|�如下：

<security-constraint>
    <web-resource-collection>
        <web-resource-name>securedappweb-resource-name>
        <url-pattern>/*url-pattern>
    web-resource-collection>
    <user-data-constraint>
        <transport-guarantee>CONFIDENTIALtransport-guarantee>
    user-data-constraint>
security-constraint>

��?URL 映射设�ؓ /* �Q�这样你的整个应用都要求�?HTTPS 讉K��Q��?transport-guarantee 标签讄��?CONFIDENTIAL 以便使应用支�?SSL�?br />
如果你希望关�?SSL �Q�只需要将 CONFIDENTIAL 改�ؓ NONE 卛_��?br />
如果是MAVEN的TOMCAT插�g�Q�则加入如下配置

<build>
        <finalName>test-dropboxfinalName>
        <plugins>
            <plugin>
