On CentOS, your MySQL/MariaDB configuration directory is located here:


In that directory there's a file called server.cnf which is where you'dset or modify that variable. By default, on mariadb when installed with yum, that file doesn't contain any specific config so you'd need to define it yourself.

I'd take a look at the following to make sure it's set correctly as there's some useful information that applies to modifying those specific variables.
