提示：关于nginx 和tomcat 己经在前面的博文己在介绍过了
第一部分：nginx反向代理tomcat
一、软件及环境
软件
| 系统 | 角色 | 用途 | 安装的软件 | ip地址 |
| Centos6.5x86_64 | nginx | 反向代理用户请求 | nginx | 172.16.249.210 |
| Centos6.5x86_64 | tomcat1 | 处理jsp请求 |
jdk+tomcat | 172.16.249.101 |
| Centos6.5x86_64 | tomcat2 | 172.16.249.100 | ||
| Centos6.5x86_64 | mog(ilefs/store) | 分布式存储静态数据 | mogilefs | 172.16.249.129 |
| Centos6.5x86_64 | mog(ilefs/store)+mariadb | 172.16.249.128 |
