linux下apache+tomcat集群詳細配置

操作系統均為：CentOS 5.1

Apache2.X服務器壹臺：IP地址192.168.232.4；安裝路徑/usr/local/apache；

Tomcat6服務器壹臺：IP地址192.168.232.5；安裝路徑/usr/local/tomcat；

Tomcat6服務器壹臺：IP地址192.168.232.6；安裝路徑/usr/local/tomcat；

配置：

Apache安裝：

#./configure --prefix=/usr/local/apache --enable-modules=so --enable-mods-shared=all --enable-proxy --enable-proxy-connect --enable-proxy-ftp --enable-proxy-/tomcat/tomcat-6/v6.0.16/bin/apache-tomcat-6.0.16.tar.gz[/url]

#tar zxvf apache-tomcat-6.0.16.tar.gz

#mv apache-tomcat-6.0.16 /usr/local/tomcat

Tomcat隨機啟動：

#vi /etc/rc.local

添加以下內容：

/usr/local/tomcat/bin/startup.sh

tomcat6配置文件server.xml：

把

<!-- You should set jvmRoute to support load-balancing via AJP ie :

<Engine name="Standalone" defaultHost="localhost" jvmRoute="jvm1">

-->

<Engine name="Catalina" defaultHost="localhost">

改成

<!-- You should set jvmRoute to support load-balancing via AJP ie :

-->

<Engine name="Standalone" defaultHost="localhost" jvmRoute="tomcatX">

<!--

<Engine name="Catalina" defaultHost="localhost">

-->

說明：

第壹臺tomcat就把jvmRoute="tomcat1"

第二臺tomcat就把jvmRoute="tomcat2"

把

<!--

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

-->

去掉註釋變為

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

***群集詳細配置***

watchEnabled="false"/>

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

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

</Cluster>

配置應用的web.xml：

在每個webapps應用中,修改配置文件web.xml文件 添加元素<distributable/>

在web.xml文件中<web-app>元素下增加以下內容：

<!--此應用將與群集服務器復制Session-->

<distributable/>

具體修改如下:

修改前:

<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="[url]/xml/ns/javaee[/url]"

xmlns:xsi="/xml/ns/javaee [url]/xml/ns/javaee/web-app_2_5.xsd[/url]"

version="2.5">

</web-app>

修改後:

<?xml version="1.0" encoding="ISO-8859-1"?>

<web-app xmlns="[url]/xml/ns/javaee[/url]"

xmlns:xsi="/xml/ns/javaee [url]/xml/ns/javaee/web-app_2_5.xsd[/url]"

version="2.5">

<!--此應用將與群集服務器復制Session-->

<distributable/>

</web-app>

配置apache的ajp負載均衡功能：

確保將以下Module的註釋去掉

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_connect_module modules/mod_proxy_connect.so

LoadModule proxy_ftp_module modules/mod_proxy_ftp.so

LoadModule proxy_/newsoft/ApacheMenual_CN_2.2new/mod/mod_proxy.html[/url]
