ERROR 2002 (HY000): Can't connect to local MySQL server
 through socket '/tmp/mysql.sock' (2)

If you have installed MySQL server using homebrew package manager and when you try to start it and you get ERROR 2002 then you need to start the service using the brew services start command.

The brew services is used to manage background services using the daemon manager launchctl on macOS.

Fix:

% brew services start mysql

Once complete, you can connect to MySQL via the terminal.

% mysql -u root
