Docker分离部署MySQL、Nginx+Tomcat复制共享

防伪码：失去只是一种姿势,得到并不等同于幸福

项目需求：

1、nginx容器作为整个架构中前端服务器监听80端口接收用户的jsp页面请求，并将用户的jsp请求分发给tomcat web容器，tomcat容器需要连接mysql数据库容器。

2、nginx容器做为前端服务器可以直接响应用户的静态页面请求，jsp动态页面请求交给tomcat容器处理（静动分离）

3、通过session复制共享：session replication，实现tomcat服务器之间同步session，使session保持一致。

注：http://yw666.blog.51cto.com/11977292/1888747，session复制共享在前文详细讲解过，此处不再赘述。

如图所示：
