Is it possible to use a remote database server for all databases including system ones on Plesk for Linux?

Question

• Is it possible to use a remote database server for Plesk and its system databases?
• Can I use an external database server for the Plesk database (psa)?

Answer

Note: It is not possible to convert an existing Plesk installation to Plesk with a remote ‘psa’ database. Such a setup can be done only before Plesk has been installed on the server, as the installation process is different

Starting from Plesk 18.0.49, it is possible to use a centralized Plesk database (psa) on an external database server by using the information on the following page of the Plesk Obsidian documentation:

Installing Plesk With Its Database on a Remote Database Server | (Plesk for Linux) Plesk Installation Without the Local Database | Plesk Obsidian documentation

Additional information related to this setup is available in the following article:
