套接字IO在端口3000上共享
我运行一个节点服务器使用socket.io 0.9.16和最近重新启动我的服务器后，我得到了上述错误：
{ [Error: connect ECONNREFUSED] stack: 'Error: connect ECONNREFUSED\n at exports._errnoException (util.js:676:11)\n at Object.afterConnect [as oncomplete] (net.js:938:19)\n --------------------\n at Protocol._enqueue ( /var/www/node_modules/mysql-activerecord/node_modules/mysql/lib/protocol/Protocol.js:110:48)\n at Protocol.handshake (/var/www/node_modules/mysql-activerecord/node_modules/mysql/lib/protocol/Protoc ol.js:42:41)\n at Connection.connect (/var/www/node_modules/mysql-activerecord/node_modules/mysql/lib/Connection.js:98:18)\n at Connection._implyConnect (/var/www/node_modules/mysql-activerecord /node_modules/mysql/lib/Connection.js:296:10)\n at Connection.query (/var/www/node_modules/mysql-activerecord/node_modules/mysql/lib/Connection.js:154:8)\n at get (/var/www/node_modules/mysql-ac tiverecord/index.js:387:15)\n at Manager.<anonymous> (/var/www/mutual.js:101:71)\n at Manager.authorize (/var/www/node_modules/socket.io/lib/manager.js:910:31)\n at Manager.handleHandshake (/ var/www/node_modules/socket.io/lib/manager.js:786:8)\n at Manager.handleRequest (/var/www/node_modules/socket.io/lib/manager.js:593:12)', code: 'ECONNREFUSED', errno: 'ECONNREFUSED', syscall: 'connect', fatal: true } nmap localhost返回：

相关的服务器代码：
var mysql = require('mysql-activerecord'), marked = require('marked'), conn = new mysql.Adapter({ server: 'server-name', username: 'user', password: 'pass', database: 'database' }), moment = require('moment'); var io = require('socket.io').listen(3000);
相关客户代码：
a=io.connect("http://server-name:3000/",{query:stuff})
先谢谢您的帮助。 让我知道你是否需要任何信息。 对不起，如果这篇文章有点长。
ECONNREFUSED与socket.io无关，如果你看错误中提供的回溯，你可以看到它来自mysql模块。 所以看起来你的mysql服务器没有监听端口3306上的server-name （或者至less有东西阻止了对它的访问）。
