CentOS/RHEL最小化安装图形化

共计 3132 个字符，预计需要花费 8 分钟才能阅读完成。

图形化，一般不再服务器中安装。为了提升系统的利用率。

CentOS 的 yum 源对应 CentOS 的源

RHEL 的 yum 源对应 RHEL 的源

我演示的 CentOS 6.5，我挂载的 RHEL6.5 的源。作为软件源，仅作思路梳理！

01、挂载 ISO 配置本地 yum 源

ISO 挂载

#mount /dev/sr0 /mnt                       \\ 把光盘挂载到“/mnt”上面
#df                                                  \\ 查看是否已经挂载

配置 yum

vi /etc/yum.repo.cdrom.repo

[rhel]

name=rhel

baseurl=file:///mnt

gpgcheck=0

enabled=1

测试 yum

yum makecache

yum repolist

02、安装图形化组件

此组件列表是 RHEL6.5 的 ISO 源 –X Window System，Centos6.5 图形化组件 –Server with GUI
[root@jiao ~]# yum grouplist  #查看群组件

 #yum -y groupinstall “Server with GUI”      \\ 安装图形化程序组

启动图形化 startx

RHEL7 命令

[root@localhost Desktop]# systemctl get-default          \\ 查看默认运行级别
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                \\ 运行级别 3：多用户界面
# graphical.target: analogous to runlevel 5                  \\ 运行级别 5：图形化界面
# # 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 \\ 设置默认图形化运行级别
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                    \\ 查看默认运行级别
graphical.target                                                    \\ 图形化设置 OK
[root@localhost Desktop]#
