hegoku / WebSocketProxy

原理

安装

安装 ws 模块:

$ npm install ws

server.js 上传到服务器,执行方式:

$ node server.js

然后配置nginx

Web Server配置

Apache配置端口转发

<VirtualHost *:80>
  ServerName xxx.com
  ProxyPass / ws://127.0.0.1:8001
</VirtualHost>

Nginx配置端口转发

map $http_upgrade $connection_upgrade {
  default upgrade;
  ''   close;
}
upstream node_ws {
  server 127.0.0.1:8001;
}
server{
  listen 80;
  server_name xxx.com;
    location /{
    proxy_redirect     off;
    proxy_pass http://node_ws;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
  }
}

使用

然后本地执行:

$ node local.js

然后就可以使用websocket来转发，比如mysql, redis等

配置参数

在local.js里:

var HOST = '127.0.0.1';   //本地ip
var PORT = 6969;          //本地端口
var SERVER = 'ws://127.0.0.1';  //远程服务器地址

var remote_options={
  ip:'127.0.0.1',      //远程被代理的服务器地址
  port:3306            //远程被代理的端口
};
