If you dont like the CLI (Command Line Interface) and looking for a Graphical User Interface (GUI), Here is a simple guide to install one. In this case, we will be using GNOME Desktop.
sudo yum -y groups install "GNOME Desktop"
This Installation would take some time depending on the Internet connection and hardware. Once it's complete, run the following command
echo "exec gnome-session" >> ~/.xinitrc
This command will inform the startx command which desktop environment to run.
You can run the command
startx and check if the GUI is working.
In order to get GUI every time you login and not to get a CLI login,
systemctl set-default graphical.target
This will now give you a Graphical interface every time you login.
Note: In order to support the GNOME you may need to use a VNC or a Remote Desktop connection. You can use the following guide to install xRDP >> Installing xRDP on CentOS 7
