Post-Install Configuration

Immediately after installation, start the database as described in To Start at Boot and run mysql_secure_installation.

As configured by the initial installation, the script has to be run by root, which authenticates itself using system credential. In consequence, mysql_secure_installation must be used as sudo:

sudo /opt/brew/bin/mysql_secure_installation

[...]
Enter current password for root (enter for none):
OK, successfully used password, moving on...
[...]
Switch to unix_socket authentication [Y/n] n
... skipping.
Change the root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
[...]
Remove anonymous users? [Y/n] Y
[...]
Disallow root login remotely? [Y/n] Y
[...]
Remove test database and access to it? [Y/n] Y
[...]
Reload privilege tables now? [Y/n] Y
[...]
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
