Tomat集群 + Tomcat集群session共享 + Nginx负载 + Nginx静态资源代理

Nginx安装配置：

具体过程参考：http://blog.csdn.net/mr__fang/article/details/40342045

Tomcat 配置文件：

参考：http://blog.csdn.net/mr__fang/article/details/40397449

Tomcat集群修改：

<Server port="18005"

<Connector port="18080"

<Connector port="18009" protocol="AJP/1.3"

server.xml 中Engine配置（集群中所有Tomcat配置一样）：

      </Host>  

    </Engine>  

web.xml配置：

主要增加 <distributable/>  标签。
