Setting Up and Using GNOME or KDE on CentOS Servers

A graphical interface can make server management much easier, especially for users who are not comfortable with the command line. Two of the most popular desktop environments for Linux are GNOME and KDE. In this tutorial, we’ll guide you through setting up and using these desktop environments on a CentOS server.

Why Use GNOME or KDE on CentOS?

GNOME:

• Modern Interface: GNOME offers a sleek and minimalistic design.

• User-Friendly: Simplifies navigation for those accustomed to graphical interfaces.

KDE:

• Customizable: KDE allows extensive customization of themes, widgets, and layouts.

• Feature-Rich: Includes advanced tools for power users.

Prerequisites

• A CentOS server with root access.

• A non-root user with sudo privileges.

• A stable internet connection.

Step-by-Step Guide

Step 1: Update Your System

Before installing any software, ensure your system is up-to-date.

				
					sudo yum update -y
				
			

Step 2: Install GNOME or KDE

Installing GNOME:

GNOME is the default desktop environment for CentOS.

				
					sudo yum groupinstall "GNOME Desktop" -y
				
			

Set GNOME as the default target:

				
					sudo systemctl set-default graphical.target
				
			

Start the graphical interface:

				
					sudo systemctl start graphical.target
				
			

Installing KDE:

KDE is available as an optional desktop environment.

				
					sudo yum groupinstall "KDE Plasma Workspaces" -y
				
			

Set KDE as the default target:

				
					sudo systemctl set-default graphical.target
				
			

Start the graphical interface:

				
					sudo systemctl start graphical.target
				
			

Step 3: Configure Remote Access

Enable RDP (Remote Desktop Protocol):

Install and configure XRDP to access the GUI remotely.

				
					sudo yum install xrdp -y
sudo systemctl enable xrdp
sudo systemctl start xrdp
sudo firewall-cmd --add-port=3389/tcp --permanent
sudo firewall-cmd --reload
				
			

Enable VNC (Virtual Network Computing):

Install and configure VNC for remote desktop access.

				
					sudo yum install tigervnc-server -y
sudo systemctl enable vncserver@:1.service
sudo systemctl start vncserver@:1.service
				
			

Step 4: Connect to Your CentOS Server

Using RDP:

• On Windows, use Remote Desktop Connection.

• On Linux, use an RDP client like Remmina.

Using VNC:

• Use a VNC viewer (e.g., TigerVNC Viewer) to connect.

• Enter the server’s IP and port (e.g., 192.168.1.100:5901).

Conclusion

With GNOME or KDE installed on your CentOS server, you now have a powerful graphical environment for easier management. Choose RDP or VNC based on your needs for remote access. Both protocols allow you to leverage the GUI effectively.
