windows下apache服务器和tomcat集群

http://lym6520.iteye.com/blog/416280

上篇文章呢将乐如何集成apache服务器和tomcat服务器，见文章http://lym6520.iteye.com/admin/blogs/412046，接下来讲讲如何tomcat集群
首先呢，修改配置文件workers.properties 

# the list of workers
worker.list=router,worker1,worker2

worker.worker1.type=ajp13
worker.worker1.host=ip
worker.worker1.port=port
worker.worker1.lbfactor=100

worker.worker2.type=ajp13
worker.worker2.host=ip
worker.worker2.port=port
worker.worker2.lbfactor=100

worker.router.type = lb
worker.router.balance_workers=worker1,worker2
worker.router.sticky_session = true
worker.router.sticky_session_force = false


这个配置文件，配置了两个tomcat和一个负载平衡器router（要注意的是，worker1和worker2分别对应各自tomcat服务器server.xml的 Engine的jvmRoute值）
这样tomcat集群基本上配置完成了，但是这样会有个问题，会话不能共享，也就是说我将同一个项目分别部署在这两个tomcat上，通过apache服务器访问这个项目，发现会话不能共享，需要重复登入，为了解决这个问题，可以再两个tomcat服务器的server.xml里的Engine元素增加以下配置信息（该配置信息可以再tomcat官网中找到）：

          </Channel>

          <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
                 filter=""/>
          <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

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


（在Membership 元素中有个bind属性，可以明确的指定当前服务器的ip地址）
这样就能保证会话可以在两个tomcat将共享了，当然在项目的web.xml中加入如下配置：

Xml代码 复制代码
  1. <!--  将会话移交给tomcat server.xml配置的会话管理器管理 -->    
  2.   <distributable />   
<!--  将会话移交给tomcat server.xml配置的会话管理器管理 --> 
  <distributable />


ok，大功告成！下次我将介绍如何在linux下配置apache服务器！
