本文记录nginx+redis+tomcat实现session共享的过程
nginx安装:http://blog.csdn.net/grhlove123/article/details/47834673
redis安装:http://blog.csdn.net/grhlove123/article/details/47783471
准备两个tomcat,修改相应的端口
修改nginx.conf加上:
[html] view plain copy
upstream backend {
server 10.10.49.23:8080 max_fails=1 fail_timeout=10s;
server 10.10.49.15:8081 max_fails=1 fail_timeout=10s;
}
修改nginx.conf的location成
[html] view plain copy
location / {
root html;
index index.html index.htm;
proxy_pass http://backend;
}
启动nginx。
下载tomcat-redis-session-manager相应的jar包,主要有三个:
wget https://github.com/downloads/jcoleman/tomcat-redis-session-manager/tomcat-redis-session-manager-1.2-tomcat-7-java-7.jar wget http://central.maven.org/maven2/redis/clients/jedis/2.5.2/jedis-2.5.2.jar wget http://central.maven.org/maven2/org/apache/commons/commons-pool2/2.0/commons-pool2-2.0.jar
下载完成后拷贝到$TOMCAT_HOME/lib中
修改两tomcat的context.xml:
[html] view plain copy
<Context>
<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<!-- Uncomment this to disable session persistence across Tomcat restarts -->
<!--
<Manager pathname="" />
-->
<!-- Uncomment this to enable Comet connection tacking (provides events
on session expiration as well as webapp lifecycle) -->
<!--
<Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
-->
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
host="10.10.49.20"
port="6379"
database="0"
maxInactiveInterval="60" />
</Context>
在tomcat/webapps/test放一个index.jsp
[html] view plain copy
<%@ page language="java" %>
<html>
<head><title>TomcatA</title></head>
<body>
<table align="centre" border="1">
<tr>
<td>Session ID</td>
<td><%= session.getId() %></td>
</tr>
<tr>
<td>Created on</td>
<td><%= session.getCreationTime() %></td>
</tr>
</table>
</body>
</html>
sessionID:<%=session.getId()%>
<br>
SessionIP:<%=request.getServerName()%>
<br>
SessionPort:<%=request.getServerPort()%>
<%
//为了区分,第二个可以是222
out.println("This is Tomcat Server 1111");
%>
启动tomcat,发现有异常:com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve 类找不到
分别打开三个jar包,确实没有这个类,解决可以参考:
http://blog.csdn.net/qinxcb/article/details/42041023
通过访问http://10.10.49.20/test/
刷新:
可以看到虽然Server从1111变为2222,但session的创建时间没有变化,这就完成了session共享。

1,安装redis并配置和启动, tomcat也做相就的下载,其他地方都有,可以在其他地方查阅。
2, 获取tomcat依赖包:
Tomcat使用 从https://github.com/xetorthio/jedis/downloads下载jedis作为java的redis客户端,
从https://github.com/jcoleman/tomcat-redis-session-manager/downloads下载tomcat的redis session manager插件
从http://commons.apache.org/proper/commons-pool/download_pool.cgi下载apache的common pool2包,2.2,将这几个jar包拷贝到tomcat7的lib目录下
包有: redis2.8、jedis.jar、common-pool2.2.jar、tomcat-redis-session-manager-1.2-tomcat-7.jar
3 配置 tomcat
在https://github.com/jcoleman/tomcat-redis-session-manager 这里面文章看到的配置为:
<Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
<Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
host="localhost" <!-- optional: defaults to "localhost" -->
port="6379" <!-- optional: defaults to "6379" -->
database="0" <!-- optional: defaults to "0" -->
maxInactiveInterval="60" <!-- optional: defaults to "60" (in seconds) -->
sessionPersistPolicies="PERSIST_POLICY_1,PERSIST_POLICY_2,.." <!-- optional -->
sentinelMaster="SentinelMasterName" <!-- optional -->
sentinels="sentinel-host-1:port,sentinel-host-2:port,.." <!-- optional --> />
而下载的包tomcat-redis-session-manager-1.2-tomcat-7-java-7.jar或tomcat-redis-session-manager-1.2-tomcat-7.jar
4 相关包的里面并没有类:com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve
所以从https://github.com/jcoleman/tomcat-redis-session-manager直接下载源码:
发现源码里面存在相应的类,同时源码(tomcat-redis-session-manager)依赖了tomcat其他的包:tomcat-juli.jar
而tomcat默认是没有这些包的,从http://mirrors.cnnic.cn/apache/tomcat/tomcat-7/v7.0.57/bin/extras/ 下载tomcat-juli-adapters.jar和tomcat-juli.jar两个包,放在apache-tomcat-7.0.57\lib目录下,同时将tomcat-juli.jar放在apache-tomcat-7.0.57\bin目录下
同时将编译tomcat-redis-session-manager的源码,通过相应的依赖包common-pool2.2,jedis以及tomcat-juli.jar编译,
并打成自己的jar包,我已经上传在:
http://download.csdn.net/detail/qinxcb/8279761 然后将这个依赖包放在apache-tomcat-7.0.57\lib目录下,删除网上下载的tomcat-redis-session-manager-1.2-tomcat-7.jar.

tomcat2 | 10.10.49.15 | 8081 | 7.0.40 | 1.7.0_25 |
[html] view plain copy
