When setting up my Apple M1 Macbook Pro I was experiencing the issue of the following error message being thrown:

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

My fix was to modify the MySQL config file:

nano /usr/local/etc/my.cnf

Append the following lines:


Then run:

brew services restart mysql@5.7

This fixed my issue, and I was then able to connect successfully with my DB client.

This works!

On the Apple Silicon:

brew remove mysql
rm -rf /opt/homebrew/var/mysql
brew install mysql
mysql.server start
mysql -uroot

just running this already fixed it for me
