所以我遵循了这里描述的所有步骤： https://devcenter.heroku.com/articles/amazon_rds
当我运行heroku config命令时，我得到：
DATABASE_URL: mysql2://[username]:[password]@hostname...
所以我在./config文件夹中添加了配置和证书
当我尝试登录时，连接超时，这就是日志中的内容：

答案 0 :(得分：3)
无法从heroku访问您的rds端口/主机。更改数据库security group并允许heroku ip连接tcp / 3306
另请注意，node-mysql确实not yet支持ssl连接。如果您需要安全地连接到rds，可能需要使用node-mysql2或node-mariasql
