How to use a new partition as MariaDB's data folder

Note

• This is not an ideal solution at all, but I had to go through this since a standard path to change the data folder of MariaDB failed on me.
• This instruction is a follow-up on How to set up a VM that has a local copy of Wikipedia and How to increase a VM's disk space, and thus, this will not help other situations.

Changes from previous situations

• You will remove mariadb and mariadb-server from the VM first
• You will remove mariadb related files such as /etc/my.cnf and /var/lib/mysql

Note

The following steps are based on a Vagrant VM box which does NOT use LVM for a root partition, which seems to be the case for the official CentOS box.
