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:

tmpdir=/tmp
user=root

Then run:

brew services restart [email protected]

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

@seemly Thanks for this

Thanks <3

This was very helpful. I also had to do:

rm /usr/local/etc/my.cnf

Something I had done previously had resulted in a my.cnf file that prevented MySQL from working (I was getting the dreaded ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) error).

Thank you! This was what I needed!

Awesome Thanks 😊🙌🏻

saved my day! Thank you :)
