3/10 skill level here....
I've installed owncloud and they recommend using something other than sqlite for a database. I've already heard of and used MariaDB in the past, however had someone else set it up for me. The point of this is to learn, without breaking things along the way. I know how to download and save the .sql backups for future upload. But how do I tell virtualmin and my server (Centos 7), to use MariaDB instead.
I'm great at using the functions, but lack the experience to know where to go to make changes to how the server functions.
TLDR: Migrate from SQLite to MariaDB using Virtualmin. MariaDB already installed.
