Hi CHBMB,
Thanks for the easy to follow write-up. I'm having an issue. I followed your guide exactly, this is my first time installing either mariaDB or Nextcloud. I didn't previously have an Owncloud install. When I'm at the Next Cloud setup screen and enter all my data, i get the following error (attached). I also attached the custom.cnf screenshot. I'm using Ubuntu, so I don't think there is any issues with how i edited the file (I used Gpedit, and confirmed it looks fine under VIM). I restarted MariaDB after changing the custom.cnf.
Any thoughts?
Edit: I'm getting this in the maraidb logs: "Warning: World-writable config file '/etc/mysql/conf.d/custom.cnf' is ignored"
Edit2: Got it working. Had to chmod 664 the custom.cnf file and restart mariadb.
