List machine installed package yum grouplist The reason for this article is mostly for documentation purposes for myselfįirst list the available meta-package groups installed on the OS: 1.
Hence in this article, I'll show how it can be removed on CentOS Linux 7 / 8 and 9. Removal of Graphics is usual operation for sysadmins thus there is plenty of info on the net,how this is done on CentOS 7 and COS 8 but unfortunately as of time of writting this article, couldn't find anything on the net on how to Remove GUI environment on CentOS 9. Removal of GUI across CentOS is similar but slightly differs.
Even worse a Graphical Environment on a Production server poses a security breach as their are much more services running on the OS that could be potentially hacked. That's really not needed on "headless" monitorless Linux servers as this wastes up for nothing a very tiny amount of the machine CPU and RAM and Disk resource on keeping services up and running. If you have installed recent version of CentOS, you have noticed by default the Installator did setup Xserver and GNOME as Graphical Environment as well the surrounding GUI Administration tools.
