Question

我是nodejs和socket.io的新手我尝试通过socket.io进行简单聊天，与我的数据库连接。但是在使用node.js连接到主机时出现问题。我正在使用亚马逊服务器。请帮我解决这个问题。这是我的代码： -

    var bodyParser = require('body-parser');
    var express = require('express');
    var config = require('./config/config');
    var io = require('socket.io')();
    var openDB = require('json-file-db');
    var db = openDB('db.json');
    var mysql = require('mysql');
    var gcm = require('node-gcm-service');
    var apn = require('apn');

    var app = express();
    app.listen(config.HTTP_PORT); // 3000
    app.use(bodyParser.json());

    io.listen(config.SOCKET_PORT);//7777

    console.log("Server is up");
    var connection = mysql.createConnection({

    host : 'xx.xx.xxx.xxx',
    user : 'root',
    password : 'my_password',
    database : 'my_db'
    });

    connection.connect(function(error){
        if(!!error)
        {
            console.log(error);
            console.log('Error');
        }
        else
        {
            console.log('connected');
        }
    });
