cara install yum group

cara install yum groupinstall...setelah searching di google ku dapat sesuatu yang baru.
kalau bagi ku ini sangat baru,maklum newbie pendatang baru linux.

ku menggunakan centos 5.2 32bit.

untuk mengetahui paket di suatu group yum apa saja yang bisa di install,kita bisa tau dengan cara mengetikan

"yum grouplist",tanpa tanda petik dan hasilnya seperti ini
[root@localhost ~]# yum grouplist
