解决方案
 
在Heroku上，数据库的最佳选择是postgresql。有几个原因可以归结为：这就是Heroku的设计原理。
 
 
 
如果您只是使用rails orm，则可以使用mysql2psql gem你的开发环境和更改你的配置文件在生产中使用postgresql。
 
 
 
如果你真的嫁给了mysql，你需要安装一个heroku插件让您的应用程序启动并运行。有几个选项，但这里有一个： https://addons.heroku.com/cleardb  
 
 
 
但是真的，最好的选择是将您的应用程序迁移到postgresql，这是值得的。

解决方案
On Heroku, your best option for a database is postgresql, hands down. There are a handful of reasons that boil down to: that's how Heroku was designed to work.

If you're simply using the rails orm you can use the mysql2psql gem in your development environment and change your config files to use postgresql in production.

If you're really married to mysql for whatever reason, you'll need to install a heroku addon to get your app up and running. There are a couple options but here's one: https://addons.heroku.com/cleardb

But really, your best bet is to migrate your app to postgresql, it's worth it.
