Answer 1

Best way to find the real cause is to check the MAMP error log in MAMP > logs > mysql_error_log.err

I found the ERROR "Do you already have another mysql server running on port: 3306 ?" - which was actually the cause for my MAMP MYSQL not starting.

Port 3306 was already "busy", so I have changed it to 8306 and that solved my issue.

Answer 2

You need to leave the mysql database AS IS.

• Uninstall and reinstall MAMP Pro.
• For every WP instance that you want to have on your server (localhost), you need to create a NEW database that is not mysql.
• Go into SequelPro and add database.
• Use Duplicator to transfer your WP.

Do not use mysql for anything, it appears to be required by MAMP.

Answer 3

Just type below command in terminal:

rm /Applications/MAMP/db/mysql56/ib_logfile* 

and then restart the MAMP.

It works back perfectly.

Ok, so I tried EVERY suggestion i found here on SO and other forums I nothing worked for me. The only solution, that worked for me was to install MAMP 3 version, since I use MAMP for wordpress projects version 3 works just fine.

The easiest solution: quit MAMP and remove the log files from MAMP/db/mysql directory [ib_logfile0, ib_logfile1] and restart MAMP. For more visit http://juanfra.me/2013/01/mysql-not-starting-mamp-fix/

Remove the files ib_logfileN (N being the number) from the MAMP/db/mysql56 folder.

Then restart MAMP.

Should Work!
