获取ETIMEDOUT错误连接到AWS MySQL数据库从Heroku的

所以我按照所有的步骤： https://devcenter.heroku.com/articles/amazon_rds 获取ETIMEDOUT错误连接到AWS MySQL数据库从Heroku的

当我运行heroku config命令，我得到：

DATABASE_URL: mysql2://[username]:[password]@hostname...

所以我已经加入在./config文件夹中配置证书

当我尝试登录时，连接超时并且这是日志中的内容：

您的rds端口/主机无法从heroky访问。更改数据库security group并允许heroku ip连接tcp/3306

另请注意，node-mysql确实支持ssl连接not yet。如果你需要安全地连接到RDS，你可能想要使用node-mysql2或node-mariasql

哦，感谢node-mysql2上的负责人。我会确定切换。至于安全组，你如何确定heroku ip。如果发现这篇文章：http://blog.katworksgames.com/2012/08/19/connecting-your-heroku-app-with-its-mysql-database/，但是当我去添加一个新的安全组。这不是一种选择，我不能添加新的EC2安全组。你有任何资源可以指出你的建议吗？ – jmogera

允许所有的IP开始 - 这是否解决连接问题？ –

对不起，我不熟悉这个，但我找到了heroku应用程序的IP地址。 “ping appname.herokuapp.com”并将该IP添加到安全组，如CIDR/IP：{ipaddress}/32。你是这个意思吗？ – jmogera
