redis session恭喜

1、安裝nginx

2、用兩個虛擬機安裝兩個reids(reids1、redis2) 其中一個配置slaveof 192.168.1.86 6379（另一個redis的IP與端口）

3、安裝兩個tomcat

修改tomcat的context.xml：

<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="192.168.1.106"
port="6379" (註：一個tomcat設置對應的一個redis的IP與端口)
database="0"
maxInactiveInterval="60" />
</Context>

nginx+redis主從+tomcat一機多實例實現會話共享
