MAMP – MySQL can’t connect after OS X Crash

Problem

I had my macbook open, it went to sleep and I couldn’t wake it up.  After holding down the powerbutton for over 10 seconds, it turned on.  Everything was fine until I tried to open the MAMP home page.  MySQL couldn’t start.  the error logs showed:

InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.
120904 14:51:31 InnoDB: Unable to open the first data file
InnoDB: Error in opening ./ibdata1

Solution

Solution is to find the mysqlid process and end it.  Then restart MAMP and things should be good to go.  more details on this great post:

Another Problem

When visiting phpMyAdmin you get the following errors:

Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.”

Another Solution

Clear your browser cache.
