设置反向代理

打开ngnix的配置文件

server {
    listen 12000;//监听端口
    server_name 47.92.212.84;//网址
    access_log /data/wwwlogs/access_nginx.log combined;
    root /data/wwwroot/default;
    index index.html index.htm index.php;
    #error_page 404 /404.html;
    #error_page 502 /502.html;
    location /{//要添加的配置如下
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
  ...
}

即下面这个

proxy_pass http://127.0.0.1:8000;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
