nginx是一个轻便好用的服务器，在代理、均衡等方面比较强大，详情自行百度。
1、下载：
去官网下载windows的版本就是 http://nginx.org/en/download.html 我选的是稳定版1.8.0
2、解压：
下载完是一个压缩包，解压后就可以直接用的了
3、使用：
用命令行切换到文件目录下，输入start nginx，有一个黑框闪一下然后消失而不会像tomcat那样保留在那，就启动了：
浏览器输入localhost，如果有欢迎界面就是启动成功了：
4、配置：
最常用的就是配置conf文件夹里的nginx.conf，在这里可以配置很多东西，详细的自己去查吧=，=
5、常用命令：
启动：start nginx
更新conf文件后直接reload，不用重启：nginx -s reload
关闭：nginx -s quit
检查conf文件是否有错：nginx -t
6、完成代理，监听80端口将不同域名绑定到tomcat上的不同端口的不同项目：
这里一定要注意！！如果tomcat（或其他程序）占用了80端口，这里再监听会不行！！我弄了好久都不行，就是这个问题！（自己sb了）
这是我的nginx.conf，其实重点就是每个server的配置

另外tomcat配置文件也要有相应的配置：
Root下的index.html

这样就可以实现用nginx将不同域名绑定到不同tomcat的不同端口。
