How to upgrade Plesk MySQL from 5.1 to 5.5 on Linux

Ref. Link:

Applies to:

  • Plesk 12.5 for Linux
  • Plesk 12.0 for Linux
  • Plesk 11.0 for Linux
  • Plesk 11.5 for Linux

Plesk autoinstaller gets packages from base repositories of an operating system installed.

If MySQL 5.5 is not listed in the base repository, it will not be available for Plesk autoinstaller.

In that case, to upgrade MySQL version to 5.5, it is needed to configure a third-party repository.

On RedHat-based systems Atomic repository can be used:

# wget -q -O - | sh
# yum upgrade mysql


  • PHP package may also be upgraded during this procedure.
  • Oracle MySQL yum repository is not supported by Plesk.
