一、配置本地源
1.掛載鏡像文件
[tekkamanninja@Tekkaman-RHEL ~]$ sudo mkdir /media/RHEL
[tekkamanninja@Tekkaman-RHEL ~]$ sudo mount -o loop <iso-path> /media/RHEL
（可選）開機自動掛載鏡像文件
在/etc/fstab的最下面添加下面一句
[tekkamanninja@Tekkaman-RHEL ~]$ sudo vi /etc/fstab
<iso-path> /media/RHEL iso9660 ro,loop 0 0
2.創建repo文件
[tekkamanninja@Tekkaman-RHEL ~]$ sudo vi /etc/yum.repos.d/local_RHEL_DVD.repo
[Server]
name=Server
baseurl=file:///media/RHEL/Server
enabled=1
gpgcheck=0
[HighAvailability]
name=HighAvailability
baseurl=file:///media/RHEL/HighAvailability
enabled=1
gpgcheck=0
[LoadBalancer]
name=LoadBalancer
baseurl=file:///media/RHEL/LoadBalancer
enabled=1
gpgcheck=0
二、安裝桌面軟件包組
1.查看軟件包組
順便看看剛才掛載上的源是否可用。
[tekkamanninja@Tekkaman-RHEL ~]$ yum grouplist

2.安裝軟件組
從上面的信息中你可以看到許多的軟件組信息，自己挑一個需要的桌面軟件組安裝就好了，我先裝Desktop
[tekkamanninja@Tekkaman-RHEL ~]$ sudo yum groupinstall "Desktop"
3.測試：啟動圖形界面
在完成了軟件的安裝之後，你就可以嘗試進入X 桌面了：
[tekkamanninja@Tekkaman-RHEL ~]$ startx
但是極有可能你無法進入圖形界面，原因非常簡單，你還沒有安裝相應的X 用戶層驅動，不同的硬件有不同的驅動，所以這個不是由軟件依賴來解決的。
對於我用於練習的ThinkPad SL400來說，我得到了如下錯誤：
[ 278.139] (II) LoadModule: "nouveau"
[ 278.140] (WW) Warning, couldn't open module nouveau

for help.
[ 278.146] Please also check the log file at "/var/log/Xorg.0.log" for additional information.
[ 278.147]
所以我就通過 yum list 命令找到了相應的驅動包，然後安裝。
[tekkamanninja@Tekkaman-RHEL ~]$ sudo yum list *nouveau*
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
Updating certificate-based repositories.
Unable to read consumer identity
Available Packages
xorg-x11-drv-nouveau.x86_64 1:0.0.16-13.20110719gitde9d1ba.el6 Server
[tekkamanninja@Tekkaman-RHEL ~]$ sudo yum install xorg-x11-drv-nouveau
安裝好了之後，再“startx”,圖形界面就出來了。
其實你還可以再log中找到其他缺少的模塊，同樣的通過 yum list 命令找到了相應的驅動包，然後安裝就是了。
3.更改啟動模式 :進入桌面還是命令界面
[tekkamanninja@Tekkaman-RHEL ~]$ sudo vim /etc/inittab
# System initialization is started by /etc/init/rcS.conf
#
# Individual runlevels are started by /etc/init/rc.conf
#
# Ctrl-Alt-Delete is handled by /etc/init/control-alt-delete.conf
#
# Terminal gettys are handled by /etc/init/tty.conf and /etc/init/serial.conf,
# with configuration in /etc/sysconfig/init.
#
# For information on how to write upstart event handlers, or how
# upstart works, see init(5), init(8), and initctl(8).
#
# Default runlevel. The runlevels used are:
# 0 - halt (Do NOT set initdefault to this)
# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)
# 3 - Full multiuser mode
# 4 - unused
# 5 - X11
# 6 - reboot (Do NOT set initdefault to this)
#
id:5:initdefault:
3為多用戶界面（命令行） 5為X window圖形界面
