1、Web应用使用Nginx进行代理，内网访问则直接是访问的Nginx:80代理服务器，在外网则访问不了，所以就有一个问题需要映射网络

2、通过路由器配置将Nginx:80代理服务器80端口映射到Web主机IP的8080端口，Web主机IP的80端口给了另外一个WebApp，所以请求主页面的时候Nginx总是site:8080/Webapp地址中的8080给自动去掉了导致404错误

3、问了度娘也问了谷歌发现

port_in_redirect off;参数可以防止自动把8080端口给去掉于是就加上，但是新的问题又来了，样式什么的不出来，查看网页源码发现里面的链接地址还是site:80/Webapp/app.css

4、同时在请求方法时候发现还是会自动把8080端口给自动去掉了变成了

site:80/Webapp/action导致404错误，于是继续度娘谷歌无果

5、在查看Nginx的一些参数的时候发现反向代理里面有一个参数



proxy_set_header Host $host;于是去查看了相关源码解释并将参数改成这样

proxy_set_header Host $host:8080;再次请求主页，并执行相应方法，所有问题均解决

以下是配置文件配置：

worker_processes  4;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;
