1.下载相关的jar，放入到Tomcat的lib目录下

https://github.com/jcoleman/tomcat-redis-session-manager/downloads tomcat-redis-session-manager-1.2-tomcat-7-java-7.jar(根据服务器配置选择)

https://github.com/xetorthio/jedis/downloads jedis-2.1.0.jar

http://commons.apache.org/proper/commons-pool/download_pool.cgi commons-pool-1.6.jar

2. 在tomcat的conf目录下context.xml中加入如下内容

<Valve className="com.radiadesign.catalina.session.RedisSessionHandlerValve" />
<Manager className="com.radiadesign.catalina.session.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) --> />

 3.配置nginx

upstream tomcat{
        server localhost:8080 weight=5;
        server localhost:9080 weight=5;
    }

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   html;
            index  index.html index.htm;
            proxy_pass http://tomcat;
        }

 4.启动nginx,redis,tomcat即可
