How to forward request to Node.js from nginx with tcp_proxy_module?

Question

Now, I had patched nginx with the nginx_tcp_proxy_module, and it is running OK on port 8080.

How do I connect the clients to port 80 of nignx, not port 8080 of Node.js, so that having the nginx forward the request to Node.js?

Answer 1

Just change 8080 to 80. But TCP and HTTP on the same port is not possible.

Aleternative solution:

• Use HAProxy on port 80
• Set up nginx to listen on port 81
• Run your node.js app on port 8080
• Configure HAProxy to
  • forward Host: your.nodejs.socketio.com to 127.0.0.1:8080
  • forward everything else to 127.0.0.1:81

If you go down this route you will probably want to preserve client IPs:

• Configure HAproxy
• Use RealIP module in nginx

• Use X-Forwarded-For in socket.io

  socketio.handshakeData = function(data) {
      var d = socketio.Manager.prototype.handshakeData(data);
      d.ip = data.request.headers['x-forwarded-for'] || data.request.connection.remoteAddress;
      return d;
  };
