My mamp mysql server won\'t turn on. I tried executing /Applications/MAMP/bin/startMysql.sh but that gave me this error :
101110 05:50:31 mysqld_safe
Well I'm glad for you it fixed itself on its own ;)
From the look of your error file, it looks like you already had an instance of MySQL running... Not sure if this works on a mac, but you could try :
pidof mysqld
If this outputs something (one or several numbers), then MySQL is running. If the output is empty, then it is not.
