As part of the Version 92 release, cPanel is offering an open beta testing period for CentOS 8. While we do not anticipate any issues, we cannot make any guarantee of performance nor would we recommend utilizing CentOS 8 and cPanel in a production environment.
Once you have a server provisioned with CentOS 8 as your operating system, you can install cPanel & WHM as you would normally.
Do understand that initial support for CentOS 8 will be limited and the potential for unexpected performance does exist. If any error or issue is discovered, please submit a ticket including all of the steps taken to reproduce (or solve) the error to our Support Department. You can submit a ticket either through the Create Ticket interface in WHM or through our Support Portal.
