先把安装光盘mount到系统中。

如果安装映像mount到/mnt/DVD目录下

[ncapp@nrb-ncapp-p01 ~]$ mount -l

/dev/mapper/vg_nrbncappp01-LogVol00 on / type ext4 (rw)

proc on /proc type proc (rw)

sysfs on /sys type sysfs (rw)

devpts on /dev/pts type devpts (rw,gid=5,mode=620)

tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")

/dev/sda1 on /boot type ext4 (rw)

/dev/mapper/vg_nrbncappp01-LogVol02 on /home type ext4 (rw)

none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

/dev/sr0 on /media/RHEL-6.8 Server.x86_64 type iso9660 (ro,nosuid,nodev,uhelper=udisks,uid=0,gid=0,iocharset=utf8,mode=0400,dmode=0500) [RHEL-6.8 Server.x86_64]

/dev/sr0 on /mnt/DVD type iso9660 (ro) [RHEL-6.8 Server.x86_64]

本文主要是通过yum安装，所以需要修收配置文件, 通过vi /etc/yum.repos.d/rhel-source.repo,增加红色部分代码。

[ncapp@nrb-ncapp-p01 etc]$ cd yum.repos.d/

[ncapp@nrb-ncapp-p01 yum.repos.d]$ ls

packagekit-media.repo  redhat.repo  rhel-source.repo

[ncapp@nrb-ncapp-p01 yum.repos.d]$ cat rhel-source.repo

[ncapp@nrb-ncapp-p01 yum.repos.d]$

查看已安装的包，和可安装的包，图形界面主要与这两个包有关系，主要与以下标记红色的包有关系，可以通过 yum groupinstall "X Windows system",  yum groupinstall "Desktop" 分别安装这两个包

[ncapp@nrb-ncapp-p01 yum.repos.d]$ yum grouplist

Done

安装到这里就可以启动"startX",但是linux不建议有root直接登陆图形界面，我们可以新建一个普通用户。

[ncapp@nrb-ncapp-p01 yum.repos.d] useradd xxx

[ncapp@nrb-ncapp-p01 yum.repos.d]passwd xxx

至此，已经可以通过新建的用户使用startx进入图形界面了，但是如果这时重启的话还是会进行命令行界面，所以需要调整开机进行桌面还是命令界面。

[root@redhat ~]#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:3:initdefault: 将上面红字部分的  3改成5

3为命令行界面   5为X window图形界面

删除redhat订阅：

rhel6.1新增了一个redhat订阅，没有用，可以删除

[root@redhat ~]# yum remove subscription*

安装桌面右键终端：[root@redhat ~]# yum install nautilus-open-terminal
