无法将nodejs连接到mysql

Question

我Node.js 0.10.31在Windows mySQL 5.5.35上运行,而我的虚拟机ubuntu在192.168.2.150上运行.现在要将节点js连接到mysql,我使用了以下连接器:

https://github.com/felixge/node-mysql

代码:

var mysql = require('mysql');
var connection = mysql.createConnection({
host : '192.168.2.150',
user : 'root',
password : '*****',
port : 3306
});

connection.connect(function(err) {
if (err) {
console.error('error connecting: ' + err.stack);
return;
}

console.log('connected as id ' + connection.threadId);
});


connection.query('SELECT 1', function(err, rows) {
// connected! (unless `err` is set)
console.log(err, rows);
});

在my.cnf文件中bind address是0.0.0.0.而且,在用户表中我已经授予了所有数据库的权限root@192.168.2.150.但是,我仍然无法从节点连接到mysql,它会出现以下错误.我甚至尝试过Node js 0.8.2版本,但它仍然不起作用.任何人都可以指出错误吗？

错误:

更新:

我也尝试过其他用户,并在数据库中授予他们完全权限.但仍然无法解决错误.但奇怪的是我能够连接mysql客户端

正如@Paul所说,这不是NodeJS的问题.如果仔细观察您正在授予用户root@192.168.2.150(表示"用户root连接IP 192.168.2.150")的权限,但是出现错误消息:

Access denied for user 'root'@'192.168.2.99'

尝试为运行NodeJS实例的IP(192.168.2.99)提供root权限,它应该可以工作.
