hello..

i would like to know how to install kde / gnome desktop on centos5 but not use yum,because my yum always fails due proxy problem

thank you

Greetingz!

Re-run the installation from an install DVD, just make sure you don't format the filesystems first!

If you installed Centos with the standard dvd you should be able to install them off of the install cd. Can't remeber how right at the moment though.

I have centos installed, proxy is simple to solve: edit /etc/yum.conf and add these lines:
proxy=http://yourproxyaipddress:yourproxyport
proxy_username=user
proxy_password=password

and make a "system constant" by adding these to your /etc/profile
export http_proxy="http://user:yourpassword@yourproxyipaddress:yourproxyport"
export ftp_proxy="http://user:yourpassword@yourproxyipaddress:yourproxyport"

Im not sure, but if you try to work only with local repo, your cd media used for install, you can do this:

yum groupinstall "X Window System" "GNOME Desktop Environment" or
yum groupinstall "X Window System" "KDE (K Desktop Environment)"

You may also want to add some other groups from the list like "Graphical Internet" or "Office/Productivity"

OR, if this a fresh install ... you can format and reinstall the system, and at the software options select your favorite interface ... a little hit: I use CentOS as server, and for this is a option "server gui" based on gnome, very light and install a good number (not too much) software for adminsitrate the server ... very good.
