Answer 1

If you don't have any important data, the easiest would be to reinstall MariaDB from scratch (otherwise skip this step), e.g.

mv /usr/local/var/mysql /usr/local/var/mysql.bak
brew reinstall mariadb

Then fix the permissions by:

sudo chmod -R u+rwX,g+rwX,o-rwx /usr/local/var/mysql
sudo chown -R $USER:_mysql /usr/local/var/mysql

Restart MariaDB services by:

brew services restart mariadb

Consider configuring your MariaDB credentials by running:

mysql_secure_installation

Troubleshooting

• In case it still doesn't work, check the logs for any further issues by:

  tail /usr/local/var/mysql/*.err
  

• For example check if in old config file consist any invalid settings, as they may be not supported anymore.
