Freak MySql error with MAMP

Question

• I setup MAMP Pro. Before that i setup and deleted MAMP and XAMPP. I maniacally deleted all the files of the former two. Since then Apache is not running on Mamp default port 8888 and - MySql is just not running whatsoever.
• One line says "check if mysqld process isnt already running" i checked that and it is not ! -Here is the error log.

Answer 1

Just search for "Activity Monitor" application on MAC and search for any task called mysql and end it. Then restart MAMP it will work. Hope it helps someone.

Answer 2

End any mysql or mysqld task (or other) in your Activity Monitor application.

Answer 3

If you cannot kill them with Activity Monitor, in Terminal do
$ ps aux | grep mysqld
The 2nd column is the process id, and you can stop it with (if it is 1234)
$ kill 1234
