How do you properly configure remote MySQL administration?

I’ve set up a mysql cluster, and my remote API node is at I can connect to that machine and issue api commands, so I know that much works.

I’ve gone into the module configuration, and changed it away from localhost to I get the error that MySQL is not running on this system, cannot list databases…?

Any idea what I need to do?

Nevermind, stupid me. I hadn’t allowed remote root. D’oh.
