By default, CentOS 7 installed as minimal vps, user intervention is required to change the installation type. This guide will help you to install GUI on CentOS 7 on the top of the minimal server installation.
Install Gnome GUI on CentOS 7
Install Gnome GUI by issuing the following command
yum groupinstall "GNOME Desktop" "Graphical Administration Tools"

ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target
Reboot the system
After you reboot the system , the system will enter into the Gnome GUI interface automatically.

After logging in to the GNOME Desktop, you can now go to System > Administration > Add/Remove Software to manage application in CentOS. By using this wizard, you can install various applications similar to yum but through a GUI. Applications installed using this method will appear in the Application menu list.
