I have MAMP Pro running on OS X 10.7.2 and it uses port 3306 for MYSQL. It was running fine until this morning when I installed a trial of WebStart. I subsequently did not like Webstart and quit and uninstalled it. My problem now is that MAMP Pro will not Start MYSQL. The log shows:
Check that you do not already have another mysqld process using the same InnoDB data or log files.
I ran this in terminal:
... and it returned:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME mysqld 3966 _mysql 10u IPv4 0xffffff802505c880 0t0 TCP localhost:mysql (LISTEN)
However, I am not really sure what this means and what to do. I suspect that WebStart put this other process in place for port 3306.
