Remove MySQL completely (Apple Silicon Version)

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

subl /etc/hostconfig`
has a hanging backtick

Also, not everyone has sublime text. Better to simply say "edit this file".

Thanks @commadelimited, gist updated.

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 mysql@5.7

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 :)

Append the following lines to:

On the Apple Silicon:

brew remove mysql
rm -rf /opt/homebrew/var/mysql
brew install mysql

brew remove mysql rm -rf /opt/homebrew/var/mysql brew install mysql mysql.server start mysql -uroot
this would work , but I noticed that there is another version of mysql on my mac:
> mysql -V mysql Ver 14.14 Distrib 5.7.24, for osx11.1 (x86_64) using EditLine wrapper
Later use this command :type -a mysql
It shows that anaconda3 installed a old version automatically.Ops....
mysql is /opt/anaconda3/bin/mysql
Remove it , then reinstall.
