The Plesk’s control panel allows a server administrator to set up new websites, reseller accounts, e-mail accounts, and DNS entries through a web-based interface. The administrator can create client and site templates, which predetermine the resource allocation parameters for the domains and/or clients to register a created extension in Plesk. When the registration is done, the extension appears in the Extensions list of the Server Administration Panel. The following command is used to register the Mod_1 extension.
Command:
plesk bin extension -r Mod_1
