RHEL 6.6安装桌面环境GNOME

RHEL 6.6安装桌面环境GNOME

在测试服务器（Red Hat Enterprise Linux Server release 6.6）需要安装桌面系统环境，于是选择GNOME桌面环境安装。

一：检查系统的运行级别以及是否安装了桌面环境

[root@localhost ~]# runlevel
N 3
[root@localhost ~]# yum grouplist | more
Loaded plugins: product-id, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-
manager to register.
Setting up Group Process
Installed Groups:
  Additional Development
  Base
  Console internet tools
  Directory Client
  E-mail server
  Fonts
  Graphical Administration Tools
  Hardware monitoring utilities
  Java Platform
  Large Systems Performance
  Legacy UNIX compatibility
  Legacy X Window System compatibility
  NFS file server
  Network file system client
  Networking Tools
  PHP Support
  Performance Tools
  Perl Support
  Scientific support
  Security Tools
  Server Platform
  System Management
  System administration tools
  TurboGears application framework
  Web Server

也可以使用下面命令验证是否安装桌面环境组件

[root@localhost ~]# ps -A | egrep -i "gnome|kde|mate|cinnamon|lx|xfce|jwm"

[root@localhost ~]# 

二：安装桌面环境相关软件组

使用yum grouplist 可以看到有Desktop、Desktop Platfrom、X Window System、Graphics Creation Tools等桌面环境有关的软件组件可以安装

[root@localhost ~]# yum groupinstall "Desktop" "Desktop Platform"

[root@localhost ~]# yum groupinstall "X Window System" "Graphics Creation Tools"

三：修改系统的启动级别为 5

[root@localhost ~]# vi /etc/inittab
# inittab is only used by upstart for the default runlevel.
#
# ADDING OTHER CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# 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:

将系统的启动级别从3修改为5，然后重启系统后，重启过后出现下面界面，按照提示操作即可。操作完成后重启系统即OK。
