服務(wù)器維護CentOS/RHEL最小化安裝圖形化

服務(wù)器維護小知識圖形化，一般不再服務(wù)器中安裝。為了提升系統(tǒng)的利用率。
CentOS的yum源對應(yīng)CentOS的源
RHEL的yum源對應(yīng)RHEL的源
服務(wù)器維護小知識我演示的CentOS 6.5，我掛載的RHEL6.5的源。作為軟件源，僅作思路梳理！
01、掛載ISO配置本地yum源
ISO掛載
#mount /dev/sr0 /mnt                       \\ 把光盤掛載到“/mnt”上面
#df                                                  \\查看是否已經(jīng)掛載
配置yum
vi /etc/yum.repo.cdrom.repo
[rhel]
name=rhel
baseurl=file:///mnt
gpgcheck=0
enabled=1
測試yum
yum makecache
yum repolist
02、安裝圖形化組件
服務(wù)器維護小知識此組件列表是RHEL6.5的ISO源--X Window System，Centos6.5圖形化組件--Server with GUI
[root@jiao ~]# yum grouplist  #查看群組件

 #yum -y groupinstall "Server with GUI"      \\ 安裝圖形化程序組
啟動圖形化startx
 
RHEL7命令
[root@localhost Desktop]# systemctl get-default          \\查看默認運行級別
multi-user.target
[root@localhost Desktop]# cat /etc/inittab
# inittab is no longer used when using systemd.
#
# ADDING CONFIGURATION HERE WILL HAVE NO EFFECT ON YOUR SYSTEM.
#
# Ctrl-Alt-Delete is handled by /etc/systemd/system/ctrl-alt-del.target
#
# systemd uses 'targets' instead of runlevels. By default, there are two main targets:
#
# multi-user.target: analogous to runlevel 3                \\運行級別3：多用戶界面
# graphical.target: analogous to runlevel 5                  \\運行級別5：圖形化界面
# # To set a default target, run: # # ln -sf /lib/systemd/system/.target

/etc/systemd/system/default.target #
[root@localhost Desktop]#
systemctl set-default graphical.target \\設(shè)置默認圖形化運行級別
rm '/etc/systemd/system/default.target'
ln -s '/usr/lib/systemd/system/graphical.target' '/etc/systemd/system/default.target'
[root@localhost Desktop]# systemctl get-default                    \\查看默認運行級別
graphical.target                                                    \\圖形化設(shè)置OK
[root@localhost Desktop]#
