RHEL 6.6安裝桌面環境GNOME

在測試伺服器（Red Hat Enterprise Linux Server release 6.6）需要安裝桌面系統環境，於是選擇GNOME桌面環境安裝。

一：檢查系統的執行級別以及是否安裝了桌面環境

[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驗證是否安裝桌面環境元件

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

[root@localhost ~]# 

二：安裝桌面環境相關軟體組

使用yum grouplist 可以看到有Desktop、Desktop Platfrom、X Window System、Graphics Creation Tools等桌面環境有關的軟體元件可以安裝

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

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

三：修改系統的啟動級別為 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:

將系統的啟動級別從3修改為5，然後重新啟動系統後，重新啟動過後出現下面介面，按照提示操作即可。操作完成後重新啟動系統即OK。
