• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

How to install Wildcard SSL certificate across subdomains?

I have a wildcard SSL certificate eg *.server.com which is valid for all subdomains of server.com.

I'd like to set up each hosted domain with a domain alias of the form:

domain1.com > alias domain1.server.com
domain2.com > alias domain2.server.com

I'd then like to use the wildcard certificate for all domains on the server, and if https access is required access a domain using its domain alias which matches the SSL certificate for the server.
eg for domain1.com use https://domain1.server.com

I'm wanting this primarily for secure logins, without having to set up a separate IP address for each domain.

I'm using Plesk 10.2 on CentOS 5.x

Is this possible, and if so, how do I go about implementing it? So far I haven't seemed to be able to find any way to make it work via the panel, but maybe it needs to be done manually via the terminal?
