A desktop environment is useful for certain applications which require a full graphical desktop manager. For simplicity and security, ClearOS comes with only the graphical console for enough Webconfig components to enable remote administration through a web browser.
You will need to install a great deal of packages and also be able to reboot the system. Because you will need to reboot, you can install the packages remotely over SSH or you can do so at the console by pressing Ctrl+Alt+F2.
From command line, run the following:
The purpose of this command is to get the packages up to date from the subscription that you are working from. The installation of the ClearOS Desktop will update packages from additional repositories and you will want to ensure that your system is already up to date to limit the number of packages that will be sourced in your install.
yum --enablerepo=clearos-centos groupinstall "X Window System" yum --enablerepo=clearos-centos install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts firefox
There will be quite a few packages that get downloaded and installed with these two commands.
