網(wǎng)絡(luò)問(wèn)題連不上服務(wù)器，因此選了一臺(tái)機(jī)子專門用于轉(zhuǎn)發(fā)，安裝nginx完畢后，編輯配置文件

vim /etc/nginx/nginx.conf

  map $http_upgrade $connection_upgrade {
    default upgrade;
    ''      close;
  }

  upstream websocket {
    #ip_hash;
    #轉(zhuǎn)發(fā)到服務(wù)器上相應(yīng)的ws端口
    server 1.2.3.4:9944;
  }

  server {
    #listen后面的端口號(hào)改為你自己需要的端口號(hào)
    listen 9944;
    #server_name改為你自己的外網(wǎng)ip。server_name默認(rèn)為localhost即127.0.0.1
    server_name 192.168.103.180;

    location / {
        #轉(zhuǎn)發(fā)到http://websocket
        proxy_pass http://websocket;
        proxy_read_timeout 300s;
        proxy_send_timeout 300s;

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        #升級(jí)http1.1到 websocket協(xié)議  
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection  $connection_upgrade;
    }
  }

然后重載配置

nginx -s reload
