Apache代理与Tomcat做负载过程并且实现session共享

1、修改apache http server配置文件http.conf，首先load三个model，代码如下：

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so

ProxyPass / balancer://tomcatcluster/

ProxyPassReverse / balancer://tomcatcluster/   
  
<Proxy balancer://tomcatcluster>  
BalancerMember ajp://localhost:8509 route=a  
BalancerMember ajp://10.1.32.234:8510 route=b
BalancerMember ajp://localhost:8510 route=c 
</Proxy>

# 警告：以下这段配置仅用于调试（监控），绝不要添加到生产环境中！！！ 此处是监控代理负载的Tomcat群状态
<Location /balancer-manager>
    SetHandler balancer-manager
    order Deny,Allow
    Allow from all
    Allow from localhost
</Location> 

<!--Define an AJP 1.3 Connector on port 8009 -->
    <Connectorport="8009"
                enableLookups="false" redirectPort="8443" protocol="AJP/1.3"  URIEncoding="UTF-8" />

还要配置其route， jvmRoute也须同前面的设置一样。。。代码如下：

<!--Define the top level container in our container hierarchy-->
    <Enginename="Catalina"defaultHost="localhost"jvmRoute="a">

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
                 channelSendOptions="6">

          <Manager className="org.apache.catalina.ha.session.BackupManager"
                   expireSessionsOnShutdown="false"
                   notifyListenersOnReplication="true"
                   mapSendOptions="6"/>
          <!--
          <Manager className="org.apache.catalina.ha.session.DeltaManager"
                   expireSessionsOnShutdown="false"
                   notifyListenersOnReplication="true"/>
          -->        
          <Channel className="org.apache.catalina.tribes.group.GroupChannel">
            <Membership className="org.apache.catalina.tribes.membership.McastService"
                        address="228.0.0.4"
                        port="45564"
                        frequency="500"
                        dropTime="3000"/>
            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="auto"
                      port="4001"
                      selectorTimeout="100"
                      maxThreads="6"/>

            <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
              <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
            </Sender>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>
          </Channel>

          <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
                 filter=".*\.gif;.*\.js;.*\.jpg;.*\.png;.*\.htm;.*\.html;.*\.css;.*\.txt;"/>

          <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                    tempDir="/tmp/war-temp/"
                    deployDir="/tmp/war-deploy/"
                    watchDir="/tmp/war-listen/"
                    watchEnabled="false"/>

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

6、最后，要在要将web.xml文件<web-app>元素的最后加上： <distributable/>。一定要加上

将apache服务器以及tomcat服务器全部启动
