Extensions Catalog – Prohibiting Installation of Extensions

You can prohibit installation of one or more extensions in the Extensions Catalog.
It is useful for various reasons. For example, if you are a service provider,
you may want to supply your customers with the exact set of extensions you have chosen.

The prohibited extensions become invisible in the Extensions Catalog. It is true for both installed and not installed extensions.

To prohibit installation of specific extensions:

1. Go to Extensions, search for the extension whose installation you want to prohibit, and then go to the extension’s page.

2. Find out the extension’s name alias. It is displayed in the last segment of the Plesk URL, which has the following pattern:

   https://<server_hostname_or_IP_address>/modules/catalog/index.php/catalog/package/<name_alias>
   

   For example, the name alias of the Amazon Route 53 extension is route53
   because Amazon Route 53 has the following URL in the Extensions Catalog:

   https://<server_hostname_or_IP_address>/modules/catalog/index.php/catalog/package/route53
   

   

3. Add an entry of the following pattern to the panel.ini file:

   [extensions]
   blacklist = name_alias1,name_alias2
   

   where

   name_alias1 and name_alias2 are the name aliases that you found out in the previous step.

   For example, to prohibit installation of Amazon Route 53 and Dropbox Backup, add the following lines to panel.ini:

   [extensions]
   blacklist = route53,dropbox-backup
   

The prohibited extension is no longer visible in the Extensions Catalog until you remove the extension’s name alias from the black list.
