I'm on Rackspace cloud servers, and I'm trying to install cPanel

It went through the whole process and its telling me that I need to change my hostname to a fully qualified domain name

I tried setting the hostname to some random domains to see if it'd work, but it didn't

Perharps if some of you know, what fully qualified domain they might be talking about, It would be great if you can explain.

BTW, I didn't even register any domain (or needed to) for the server process or to get the cPanel license, so I'm really confused as to what domain they're telling me to put in for the hostname

I changed the hostname to what you suggested and still can't get it to work. I think cPanel wants something else, I'm not sure. – user57650 Oct 24 '10 at 2:34
I installed plesk now. Plesk seems a lot easier to install. – user57650 Oct 24 '10 at 20:26
