I'm a Linux newbie and want to learn how to administer a Linux web server. I've just setup a CentOS box following one of the Perfect Setup 'howtos'. Being a Windows person for so long I am used to working in a GUI environment, but having followed the 'Perfect Setup' (which is very good) I am left with a Linux box with a command line interface. So I guess my question is, what's the easiest way for me to get up and running on my new Linux box? Can I install one of the Linux GUI desktops? and if I do, can I revert back to a command line interface afterwards? Thanks and sorry for the dumb questions.
