MySQL server does not start with MAMP

Environment

• Mac OS Big Sur Ver 11.6
• MAMP Ver 6.5
• PHP Ver 7.4.21
• MySQL Ver 14.14 Distribute 5.7.34

Issue

I was using MySQL on MAMP but now having errors after restarted my mac.

First, I got this error.

$ mysql -u root -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock' (2)

And, the Stop-icon on MAMP is orange (I think it was usually green).

What I did so far:

1. Checked if the mysql.sock file exists.

$ ls /Applications/MAMP/tmp/mysql/

2. Created mysql.sock file.

$ touch /Applications/MAMP/tmp/mysql/mysql.sock

3. Tried to start mysql again. (The Error message changed from (2) to (38).)

$ mysql -u root -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock' (38)

4. Tried to start mysql server.

$ mysql.server start
-bash: mysql.server: command not found

5. Checked if the path is set.

$ mysql --version
mysql  Ver 14.14 Distrib 5.7.34, for osx10.12 (x86_64) using  EditLine wrapper

6. Used the full path

$ /Applications/MAMP/Library/bin/mysql -u root -p
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock' (2)

This issue was resolved by removing (just moved to trash) and reinstalling MAMP.
