node.js +公共mysql数据库：“连接ECONNREFUSED”

Question

我正在使用代理服务器，我试图访问以下public数据库。

连接正常使用mysql客户端，从我的工作地点：

$ mysql -A -u genome -h genome-mysql.cse.ucsc.edu -P 3306 -D hg19 -e 'select now()' 
+---------------------+ 
| now()    | 
+---------------------+ 
| 2014-03-06 01:56:36 | 
+---------------------+ 

现在，我试图做使用节点同样的事情：

var mysql = require('mysql'); 
var connection = mysql.createConnection({ 
    debug:true, 
    trace:true, 
    host : 'genome-mysql.cse.ucsc.edu', 
    port : 3306, 
    database: 'hg19', 
    user : 'genome', 
    password: '' 
}); 
connection.connect(function(err) {if(err!=null) console.log(err);}); 
connection.end(); 

它从我的工作但它会引起我的工作场所的错误

{ [Error: connect ECONNREFUSED] 
    code: 'ECONNREFUSED', 
    errno: 'ECONNREFUSED', 
    syscall: 'connect', 
    fatal: true } 

sam e错误使用：_socket: '/var/run/mysqld/mysqld.sock' as connect ECONNREFUSED - node js , sql

有关如何解决此问题的任何建议？
