Install Plesk with default MySQL Database instead of MariaDB

Plesk stopped distributing Oracle MySQL because of MySQL licensing legal aspects stuff. There is a work around but it's only supported on Windows Server 2012 and 2016. You can learn more at:

The prefer method, if you want to use MySQL, is to install MySQL afterwards and add it as a secondary database to select from.

Hi @scsa20

Thank you for sharing this. Yes I had gone through it, but that's why my query was there.

However, if I change the default MariaDB to 3307 & set MySQL to 3306, then installation of SpamAssassin breaks, because its still trying to connect to default 3306 port, which I have now given to MySQL instead of MariaDB.

Any idea?

Yes this is because it is expecting MariaDB to be running on the default port 3306. What you should be doing is leaving MariaDB's settings alone since that's how Plesk is going to be running everything and instead set MySQL to be running on port 3307.
