Database from PSQL to Mariadb

Hello everybody,
my colleague installed a new icinga2 instance with a PSQL database after a failure. However, most additional modules (X509/Vsphere) are based on MYSQL/Mariadb. So now I have Mariadb installed but can’t add new resources with MYSQL. Where can I change that?

Best Regard and thanks

If you can not select a specific database type for a resource in Icinga Web 2, then the corresponding PHP module is missing. Package name varies between distributions and versions. And you need to restart apache or php-fpm depending on your setup to recognize the newly installed module.

This is right and the solution.

Thank you so much
