登錄系統(tǒng)，使用yum 安裝

#yum groupinstall 'X Window System'  -y
安裝GNOME桌面環(huán)境
#yum groupinstall  'GNOME Desktop Environment' -y
如果安裝KDE桌面環(huán)境
#yum groupinstall 'KDE (K Desktop Environment)' -y

如果發(fā)生錯誤：
Warning: Group GNOME Desktop Environment does not exist.
No packages in any requested group available to install or update
則可以先用yum grouplist 檢查一下已安裝的組可支持的組，獲得對應(yīng)的組名再安裝

卸載GNOME桌面環(huán)境
#yum groupremove "GNOME Desktop Environment"
卸載KDE桌面環(huán)境
#yum groupremove "KDE (K Desktop Environment)"
