Step 1: Install Gnome GUI packages using the YUM command.
CentOS 7:
# yum groupinstall "GNOME Desktop" "Graphical Administration Tools"
RHEL 7:
# yum groupinstall "Server with GUI"
Step 2: Enable GUI on system startup. In CentOS 7 / RHEL 7, systemd uses “targets” instead of runlevel. The /etc/inittab file is no more used to change run levels. So, issue the following command to enable the GUI on system start.
# ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target
Step 3: Reboot the machine to start the server in the graphical mode.
# reboot
