Having worked as an amateur with Linux here and there for the last 30 years, I do understand the need to learn coding as part of using Linux, however in the case of setting up a basic mysql server without a working baseline, then it can be beyond the reach for many to get a basic server up and running.
While MariaDB and phpMyAdmin are both available to install on CassaOS, they do not actually function out of the box without days of trial and error following outdated tutorials and trial and error. Perhaps a combined MariaDB and phpMyAdmin application with preset settings?
