无法使用nodejs连接到MySQL数据库(openshift应用程序)

我有一个nodejs(带快递)openshift应用程序,它有一个MySQL数据库(因为这是我最熟悉的),我无法弄清楚如何在本地环境中连接它.我的上一个项目我使用php框架和mamp连接到本地数据库.节点的等价物是什么？这是我必须连接的代码:

 var mysql = require('mysql');

 var connection = mysql.createConnection({
  host     : '127.0.0.1',
  port     : '3307',
  database : 'test'

});

 connection.connect( function(err){
if (err){ 
    throw err;
}
else {
    console.log('Connected');
}
 });

尝试连接本地时出现以下错误:

 Error: connect ETIMEDOUT
    at errnoException (net.js:901:11)
    at Object.afterConnect [as oncomplete] (net.js:892:19)

    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)

我猜这是因为我试图本地连接到openshift设置的MySQL数据库,我收到错误.我只是不知道还有什么可以尝试.我也尝试过没有密码.

如果我切换到主机的localhost,这是我收到的错误:

Error: ER_DBACCESS_DENIED_ERROR: Access denied for user ''@'localhost' to database 'stembuds'

对不起这篇文章的篇幅,我只是不知道为什么它不起作用.

编辑:

我ssh'ed进入openshift shell来查看mysql设置.当我执行'show grants\g'命令时,这就是我收到的内容:

  Grants for adminMYXaSuf@127.11.28.130

  GRANT ALL PRIVILEGES ON *.* TO 'adminMYXaSuf'@'127.11.28.130' IDENTIFIED BY PASSWORD '*D0CE5FA2AAD801A33C9190D0B615CC92F364BE6B' WITH GRANT OPTION

此密码与提供的openhift不同.
