RHEL6.3 纯命令行文本界面下安装桌面

一.配置yum本地安装源：

su - root
mkdir /mnt/cdrom
mount -t iso9660 /dev/sr0 /mnt/cdrom
cd /etc/yum.repos.d

查看目录是否有.repo后缀文件，没有则创建一个.repo文件,文件名随意。
vi local.repo

[LOCAL]
name=local
baseurl=file:///mnt/cdrom
enable=1
gpgcheck=0

保存退出

yum clean all

二. 安装默认系统桌面(适于之前安装系统时未选中桌面安装)
1.安装桌面包
yum groupinstall “X Window System”
yum groupinstall “Desktop”
2.启动桌面
init 5
3.更改启动模式
vi /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

4.安装桌面右键终端： yum install nautilus-open-terminal
