RHEL7安装图形化

很多时候我们在安装OS的时候可能默认选择的最小化安装（Minimal Install），是没有图形化界面的。后面又想安装GUI图形化。在rhel7 平台上可以通过如下命令实现图形化安装。

show-installed是一个用python写的命令，该命令会去调用yum查看当前已安装的软件组和软件包。

启用图形界面并设置默认启动

[root@361way mnt]# startx
[root@361way mnt]#systemctl get-default
multi-user.target
[root@361way mnt]#systemctl set-default graphical.target
rm '/etc/systemd/system/default.target'
ln -s '/usr/lib/systemd/system/graphical.target' '/etc/systemd/system/default.target'
[root@361way mnt]#systemctl get-default
graphical.target
[root@361way mnt]#reboot
