Install MariaDB with brew on macOS and fix the “access denied” issue

mariadb-brew-macos.md

Attempting mysql -u root fails with Access denied for user 'root'@'localhost immediately after doing brew install mariadb and starting mariadb with brew services start mariadb.

To fix it (with MariaDB still running):

1. sudo mysql then enter your Mac user password
2. ALTER USER 'root'@'localhost' IDENTIFIED BY 'newrootpassword'; replacing newrootpassword with the password you wish to use for the MariaDB root user.
3. Ctrl-C to exit mysql.

You should then be able to connect to MariaDB with mysql -u root -p, then entering the root password when prompted.

Thanks! You saved me.
