配置Apache+Tomcat集群

操作系統：Debian6.0 (192.168.225.129 虛擬機1臺)

軟件版本：Apache-2.2.16, Tomcat-6.0.35

1.安裝軟件

    >apt-get install update

    *安裝Apache

    >apt-get install apache2

    *安裝Tomcat

    >wget http://apache.etoak.com/tomcat/tomcat-6/v6.0.35/bin/apache-tomcat-6.0.35.tar.gz

    >tar zxvf apache-tomcat-6.0.35.tar.gz

    >mv apache-tomcat-6.0.35 /user/local/tomcat

    >cp /usr/local/tomcat  /usr/local/tomcat2

    *安裝mod_jk

    >apt-get install libapache2-mod-jk

2.配置2個Tomcat

    現在/usr/local目錄中已經有2個tomcat目錄了，需要更改tomcat2的端口，防止端口沖突。

    >nano /usr/local/tomcat/conf/server.xml

    有3處的默認端口需要更改：

    1.<Server port="8004" shutdown="SHUTDOWN"> 我更改為8003

    2.<Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

        更改為7080

    3.<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

        更改為7009，其中redirectPort 8443不需要更改

    o.另外還需要在<Engine>配置中加入<Clustber>配置

    <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>  
    <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>    
</Cluster>

     x.最后2個tomcat都需要改變<Engine的 jvmRoute屬性分別為tomcat1和tomcat2，以對應之后worker.properties中的名字。

3.配置Apache以jk方式和tomcat集群

   安裝完成后apache的主目錄為/etc/apache2,安裝完mod-jk之后，mods-enabled里面會多一個jk.load

   創建文件   /etc/apache2/mods-enabled/jk.conf

    >nano /etc/apache2/mods-enabled/jk.conf

       JkWorkersFile /etc/apache2/workers.properties
       JkShmFile     /var/log/apache2/mod_jk.shm
       JkLogFile     /var/log/apache2/mod_jk.log
       JkLogLevel    info

   創建文件  /etc/apache2/workers.properties

    >nano /etc/apache2/workers.properties

       worker.list=controller1

       worker.tomcat1.port=8009
       worker.tomcat1.host=localhost
       worker.tomcat1.type=ajp13
       worker.tomcat1.lbfactor=1

       worker.tomcat2.port=7009
       worker.tomcat2.host=localhost
       worker.tomcat2.type=ajp13
       worker.tomcat2.lbfactor=1

       worker.controller1.type=lb
       worker.controller1.sticky_session=1   #可選項0,1
       worker.controller1.balance_workers=tomcat1,tomcat2

    更改/etc/apache2/sites-enabled/000-default文件

      在</VirtualHost>之前添加

       JkMount /* controller1

       (controller1對應workers.properties中的名字)

配置完成之后先后啟動tomcat和apache。

測試：

2個tomcat部署相同的應用：即首頁index.jsp顯示各自tomcat名稱tomcat1和tomcat2

通過80端口訪問應用，刷新幾次，tomcat1和tomcat2輪流顯示。
