• 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 | more

  ===========================================
  从上面的软件组信息，挑选与桌面环境有关的软件组，然后安装即可，我下面选择的软件组与输入法还有字体等桌面环境需要用到的供大家参考一下。
  
  
  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。
