Making the switch to MariaDB

[celiac101]

So I ran the mysql updater months ago to switch my server to MariaDB 10.1. The issue is that I never made changes to the my.cnf file, so I am not sure if I am actually optimizing MariaDB and using it properly. Below is my my.cnf file. I have 2 main questions:

1) Should I have specific entries for MariaDB in it?

2) Should I be using the MYISAM storage engine. It looks like the Aria is better.

How can I add the changes I need to utilize MariaDB and Aria?

Hello @celiac101,

MariaDB is considered a drop-in replacement for MySQL. Most of the configuration settings are cross-compatible, however it's possible the performance impact of those configuration settings will differ with MariaDB. Additionally, while most settings are cross-compatible, there are some compatibility issues to be aware of:

The following thread is a good starting point if you want to tune your current settings:

mysqlmymonlite.sh server stats gathering tool for cPanel Server

I recommend running the tuner with your existing settings to see what it recommends.

Thank you.

While most MySQL configurations would work just fine when used with MariaDB, it would indeed beneficial to fine tune settings individually. A few things to check would be the amount of MySQL traffic you have on your domains and then identify what settings would be best for you.
