The official startup script provided by MySQL is the old fashioned way of starting programs during startup. Apple however has decided that this will stop in future versions and that they will move over to launchd, it is currently used in Leopard and is the prefered way in controlling your deamons.
To enable it we need to create a .plist file with all the details, as MySQL is a system wide application we need to put it in
/System/Library/LaunchDaemons/ and I’m going to call it
com.diymacserver.mysql.plist. The content of the file will look like:
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
The label key should be the same as the plist file name without the .plist
The KeepAlive option will restart MySQL when it crashes or is stopped.
The RunAtLoad means it will start at boot time.
The UserName option indicates under which user the program should start.
To load and activate the .plist file and to make sure that it is started after a reboot you’ll need to load the plist file by using the command:
You can see if it loaded correctly by using the command:
This will show you all the active plist files.
If everything went correctly mysql has already started.
To stop the instance you could use:
But because of the KeepAlive option it will be restarted.
To stop the script being run at boot time you need to unload the plist file.
