[Tips] nginx端口转发

在nginx启动后，于/etc/nginx/conf.d/中，修改default.conf文件

server {
      listen       80;
      server_name  localhost;
      location / {
        proxy_pass http://IP:端口;
      }
      error_page   500 502 503 504  /50x.html;
      location = /50x.html {
        root   /usr/share/nginx/html;
      }
}

将上的proxy_pass的内容改为需要转发的目标。这样对nginx监听的端口（这里是80）的访问就会抓发给目标地址。

若要监听多个端口，直接在文件中生成多个server描述即可

server {
      listen       80;
      server_name  localhost;
      location / {
        proxy_pass http://IP:端口;
      }
      error_page   500 502 503 504  /50x.html;
      location = /50x.html {
        root   /usr/share/nginx/html;
      }
}

server {
      listen       81;
      server_name  localhost;
      location / {
        proxy_pass http://IP:端口;
      }
      error_page   500 502 503 504  /50x.html;
      location = /50x.html {
        root   /usr/share/nginx/html;
      }
}

server {
      listen       82;
      server_name  localhost;
      location / {
        proxy_pass http://IP:端口;
      }
      error_page   500 502 503 504  /50x.html;
      location = /50x.html {
        root   /usr/share/nginx/html;
      }
}
