Increase the GNOME desktop after minimal installation of CentOS

Background: After downloading the CentOS 7 installation package, install it on the virtual machine.

Come up with a problem: prompted to open Intel Vt-x.

This enters the BIOS and opens in the settings of the CPU.

Then with the excitement of the mood, began the various next installation, unexpectedly only a few minutes will be loaded.

Boot into the system only to find the minimal installation, only the character interface.

Overcoming the urge to reinstall the system, I believe Linux can install the desktop later (which is unthinkable in Windows).

Record the entire process step:

① a powerful virtual machine, mount the disc file from the virtual machine first.

② log in to the system with the root user.

③mount/dev/sr0/media mount the installation disc file.

The ④ configuration disc is a local Yum source.

1 vi /etc/yum. repos.d/local.repo2 Enter the following in the editor:3[local]  4 name=local5 baseurl=file://media/6 enabled=17 gpgcheck=0

⑤ Reload the Yum cache.

1 mkdir /tmp/repo    2mv /etc/yum. REPOS.D/*  /tmp/repo  3mv/tmp/repo/local.repo  /etc/yum.repos.d/4yum Clean all && rm-rf/var/cache/yum/*5Yum Makecache

⑥ view the groups that can be installed.

Yum grouplist

⑦ Select the GNOME desktop.

Yum groupinstall-y  "GNOME Desktop"

⑧ set the boot mode to graphical mode.

LN -sf/lib/systemd/system/graphical.target/etc/systemd/system/default.target

OK, after restarting, is it a graphical interface?
