#1

You need to bind the socket.io to the http server not the application server. Changes this to below..

您需要将socket.io绑定到http服务器而不是应用程序服务器。将此更改为以下..

var express = require('express'),
    app = express(),
    http = require('http'),
    server = http.createServer(app),
    io = require('socket.io').listen(server);

Refer Express guide for more info.
