If you selected the CentOS "server" install, CentOS does not install a desktop environment by default. This is because most servers in the enterprise are headless, that is, they do not have a monitor or keyboard, but sit in racks and are administered remotely using tools such as ssh
. You can see man ssh
and man scp
for more details.
The command that evo2 listed will install the basic default desktop environment, but it will need to be run as root. Either log in as root or, once logged in as user, use su
to switch to root.
Here's a link to the CentOS wiki. It should help a log.
