nginx+tomcatsession共享

* tomcat1 192.168.10.153* tomcat2 192.168.10.154

Tomcat 工作模式必须为Nio 模式。

##添加如下内容&＃xff0c; 注意更换 address&＃61;"192.168.10.154" 为本机IP vim /usr/local/tomcat/conf/server.xml<Cluster className&＃61;"org.apache.catalina.ha.tcp.SimpleTcpCluster"channelSendOptions&＃61;"8"><Manager className&＃61;"org.apache.catalina.ha.session.DeltaManager"expireSessionsOnShutdown&＃61;"false"notifyListenersOnReplication&＃61;"true"/><Channel className&＃61;"org.apache.catalina.tribes.group.GroupChannel"><Membership className&＃61;"org.apache.catalina.tribes.membership.McastService"address&＃61;"228.0.0.4"port&＃61;"45564"frequency&＃61;"500"dropTime&＃61;"3000"/><Receiver className&＃61;"org.apache.catalina.tribes.transport.nio.NioReceiver"address&＃61;"192.168.10.154"port&＃61;"4000"autoBind&＃61;"100"selectorTimeout&＃61;"5000"maxThreads&＃61;"6"/><Sender className&＃61;"org.apache.catalina.tribes.transport.ReplicationTransmitter"><Transport className&＃61;"org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>Sender><Interceptor className&＃61;"org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/><Interceptor className&＃61;"org.apache.catalina.tribes.group.interceptors.MessageDispatchInterceptor"/>Channel><Valve className&＃61;"org.apache.catalina.ha.tcp.ReplicationValve"filter&＃61;""/><Valve className&＃61;"org.apache.catalina.ha.session.JvmRouteBinderValve"/><Deployer className&＃61;"org.apache.catalina.ha.deploy.FarmWarDeployer"tempDir&＃61;"/tmp/war-temp/"deployDir&＃61;"/tmp/war-deploy/"watchDir&＃61;"/tmp/war-listen/"watchEnabled&＃61;"false"/><ClusterListener className&＃61;"org.apache.catalina.ha.session.ClusterSessionListener"/>Cluster>

## 修改 web文件&＃xff0c;在上面添加一行内容 vim /usr/local/tomcat/webapps/ROOT/WEB-INF/web.xml

##添加测试文件 vim index.jsp <%&＃64; page contentType&＃61;"text/html; charset&＃61;GBK" %> <%&＃64; page import&＃61;"java.util.*" %> <html> <head> <title>Cluster App Testtitle> head> <body> Server Info: <% out.println(request.getLocalAddr() &＃43; " : " &＃43; request.getLocalPort()&＃43;" ");%> <% out.println(" ID " &＃43; session.getId()&＃43;" "); // 如果有新的 Session 属性设置 String dataName &＃61; request.getParameter("dataName"); if (dataName !&＃61; null && dataName.length() > 0) { String dataValue &＃61; request.getParameter("dataValue"); session.setAttribute(dataName, dataValue); } %>body> html>

##配置 nginx负责均衡&＃xff0c;进行测试upstream tomcatserver {server 192.168.10.153:8080 weight&＃61;5;server 192.168.10.154:8080 weight&＃61;5;} location / {proxy_pass http://tomcatserver; #来自jsp请求交给tomcat处理}
