I have reinstalled the packages but I still end up with the same problems.

Best Answer

The arch wiki helped me solve this pretty quickly.

Install mariadb, afterwards run the following command before starting the mariadb.service: 

mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
mysql_secure_installation

Arch does not hold your hand, with this type of thing. I guess if you install mysql / mariadb from source this is expected.

This answer also helped me to figure out what I was looking for. https://stackoverflow.com/a/22179751/619760
