CentOS 安装图形化界面方法

登录系统，使用yum 安装

yum groupinstall 'X Window System' -y
安装GNOME桌面环境
yum groupinstall 'GNOME Desktop Environment' -y
如果安装KDE桌面环境
yum groupinstall 'KDE (K Desktop Environment)' -y

如果发生错误：
Warning: Group GNOME Desktop Environment does not exist.
No packages in any requested group available to install or update
则可以先用yum grouplist 检查一下已安装的组可支持的组，获得对应的组名再安装

卸载GNOME桌面环境
yum groupremove "GNOME Desktop Environment"
卸载KDE桌面环境
yum groupremove "KDE (K Desktop Environment)"

或者：

yum -y groupinstall Desktop 
yum -y groupinstall "X Window System"
yum -y groupinstall chinese-support 
vi /etc/sysconfig/i18n
将en_US改成zh_CN
