Question

Which MySQL versions are supported by different versions of Plesk?

Answer

Plesk Obsidian for Windows:

MySQL community edition 5.7
MySQL 8.0 as remote database server only

Plesk Obsidian for Linux:

MySQL 5.7
MySQL community edition 5.7
MySQL 8.0 is supported starting from Plesk Obsidian 18.0.33
MySQL Community Edition 8.2 and 8.3 is supported starting from Plesk Obsidian 18.0.59
MySQL Community Edition 8.4 is supported starting from Plesk Obsidian 18.0.76

Important notices about using MySQL 8.0 with Plesk

MySQL 8 community-server was tested on all supported operating systems (Plesk Obsidian for Linux Supported Operating Systems).

MySQL 8 from OS vendor was tested on Ubuntu 20.04 and CentOS/RHEL 8.

To perform upgrade of the Plesk local database server to MySQL 8

Note: Direct upgrade to MySQL 8.0 supported only from MySQL 5.7.9 and above. It is recommended to have the latest 5.7.x version before the upgrade.

Create a full server snapshot to have a possibility to rollback the changes.
Upgrade MySQL server as described in the the MySQL documentation.
Additional step for RHEL-based OS (CentOS/RHEL/CloudLinux/AlmaLinux) - install the Plesk dependency package:
for OS based on RHEL 7:

# rpm -Uvh https://autoinstall.plesk.com/mysql-server-community/plesk-mysql-server-community-centos-7.rpm

for OS based on RHEL 8:

# rpm -Uvh https://autoinstall.plesk.com/mysql-server-community/plesk-mysql-server-community-centos-8.rpm

To perform clean installation of Plesk with MySQL 8

Note: Since Plesk Obsidian for Linux uses PHP 7.3, during installation of Plesk, default authentication type will be switched from caching_sha2_password to mysql_native_password to be compatible with PHP version lower than 7.4.

Install MySQL 8 as described in the MySQL documentation.
For RHEL-based OS (CentOS/RHEL/CloudLinux/AlmaLinux) - install the package mariadb-connector-c (for RHEL 8-based OS only) and Plesk dependency package:
for OS based on RHEL 7:

# rpm -Uvh https://autoinstall.plesk.com/mysql-server-community/plesk-mysql-server-community-centos-7.rpm

for OS based on RHEL 8:

# dnf install mariadb-connector-c && rpm -Uvh https://autoinstall.plesk.com/mysql-server-community/plesk-mysql-server-community-centos-8.rpm
Install Plesk.
