Installing Plesk Extensions in Plesk Multi Server

Installing and using extensions in Plesk Multi Server is subject to certain limitations described below.

In Plesk Multi Server, you can only install extensions on the management node. You can only install extensions from the Extensions Catalog. You cannot upload custom extensions.

All extensions can be separated into three categories:

  • Can only operate on the management node.
  • Can only operate on service nodes.
  • Can operate both on the management and on service nodes.

When you install an extension that belongs to the second or third category, the extension is automatically installed on all service nodes as well.

You can see which extension belong to which category in the table below.
