nginx + memcached-session-manager 实现tomcat下的负载均衡

1. tomcat6.0 配置

memcached-session-manager 实现session共享

1.1 下载memcached-session-manager-1.6.5.jar、memcached-session-manager-tc6-1.6.5.jar(tomcat6.0)、msm-javolution-serializer-1.6.5.jar、spymemcached-2.8.12.jar、javolution-5.4.3.1.jar和couchbase-client-1.1.4.jar  共5个jar包放入tomcat的lib目录下;

1.2 context节点下增加如下配置

 <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
    memcachedNodes="n1:192.168.1.104:11211"
 sticky="false"
    requestUriIgnorePattern=".*.(png|gif|jpg|css|js)$"
    sessionBackupAsync="false"
    sessionBackupTimeout="100"
    transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
    copyCollectionsForSerialization="false"
    />

2.nginx-1.5.6 配置
