I'm trying to reset my root password on a macports installed MySQL on OS X. But none of the ways to do this that I can find works, for various reasons. One reason common to all is that I can't stop the mysql deamon.

As I understand it, I should be able to stop it with

sudo launchctl stop org.macports.mysql5

Which makes absolutely no difference. No error message, nothing. Is launchd really this sucky, or do I misuse it? Reasonably it should give me an error when it fails, but nope, nothing.

Trying to kill the processes with kill -9 just makes them restart again, so that doesn't work either.

I also tried

sudo launchctl unload org.macports.mysql5

But that gives me this error:

launchctl: Couldn't stat("org.macports.mysql5"): No such file or directory

(And I must confess I don't understand what "Unload configuration files and/or directories" means, which is what the Unload command apparently does according to the little docs I can find).

So, what now?

The correct answer is

sudo launchctl unload -w /Library/LaunchDaemons/org.macports.mysql5.plist

And you start it with

sudo launchctl load -w /Library/LaunchDaemons/org.macports.mysql5.plist

Thanks to kh13org for the pointer.

  • The file name may be slightly different. For example, on my system, the name is /Library/LaunchDaemons/org.macports.mysql55-server.plist.
