How To Install KDE Plasma GUI In CentOS 7 Linux

How To Install KDE Plasma Desktop In CentOS

By default a full installation of CentOS 7 will have the GNOME graphical user interface (GUI) installed and it will load up after system boot, however if we have installed CentOS without a GUI installed we can always install one later, or optionally we can install a different GUI.

This quick guide will cover how to install the KDE Plasma desktop on CentOS 7, which will provide a GUI for working with the Linux system. While I don’t suggest using a GUI on a production server, it’s a good option if you’re using CentOS as a desktop.

Linux VS Windows Web Server Benchmarks

Windows vs Linux web server benchmark test

Following on from my recent Linux web server benchmarks and Windows web server benchmarks, I noticed that in general IIS appeared to perform better than all Linux based web servers that I’d previously tested.

As my Linux results were completed in March last year, I’ve run some of the tests again with the most up to date versions of each web server to ensure that the best performance can be achieved.

So let’s find out how Linux and Windows based web servers compare against each other in a static workload speed test.

25 Useful DNF Command Examples For Package Management In Linux

DNF Command Examples For Linux

Dandified Yum (DNF) is an RPM based package manager which is used to install and update packages in various Linux distributions including CentOS, RHEL and Fedora.

Install DNF Package Manager

DNF, or Dandified Yum, which is the next major version of the Yum package manager was introduced with Fedora 18. As of Fedora 22, it has become the default package manager.

As you may know, the Fedora Linux operating system is essentially a bleeding edge testing ground for packages that may be included in RHEL/CentOS based distributions in the future.

It is therefore likely that in some future release, RHEL/CentOS will also make use of DNF rather than Yum to take advantage of the new features, so let’s take a look at what’s involved in installing and using DNF in CentOS Linux so that we can be ready for it when it’s made default.
