linux Centos 6.5 安装桌面环境GNOME

一、首先查看系统的运行级别以及是否安装了桌面环境　　1、使用命令 runlevel 查看当前的运行级别 ，如图所示　　2、使用命令 yum grouplist | more 查看是否安装了桌面环境的组件，如图所示






二、再次从上面分析的结果看到，当前运行级别是3，而且也没有安装桌面环境的软件。　　然后我们使用命令查看一下桌面有哪些桌面环境的软件，然后装显示出来的软件组件就可以了。例如：[root@localhost ~]#[root@localhost ~]# yum grouplist | moreLoaded plugins: fastestmirrorSetting up Group ProcessLoading mirror speeds from cached hostfile* base: mirrors.usc.edu * extras: centos.mirror.ndchost.com *updates: mirror-centos.hostingswift.comInstalled Groups: E-mail server Security Tools StorageAvailability Tools iSCSI Storage Client

yum groupinstall -y "Desktop" "Desktop Platform" "Desktop Platform Development"　 "Fonts" 　"General Purpose Desktop"　 "Graphical Administration Tools"　 "Graphics Creation Tools" 　"Input Methods" 　"X Window System" 　"Chinese Support [zh]"　"Internet Browser"
后面的是安装软件过程，需要等等一阵时间。













三、安装好了桌面环境的软件，然后再修改一下系统的启动级别 为 5　　编辑/etc/inittab文件，修改启级别为5，如下图，然后重新启动就可以进入桌面环境了。因为我这是远程环境的，只是运用了命令行，可以使用VNC进行桌面环境的远程。









四、重启的过程中，设置一下桌面环境的几个参数就可以正常进入登陆界面了，谢谢。
