The ‘touch’ command is used to modify the time stamp of an existing file, or to create new empty files.
Touch comes from the GNU Coreutils package and should be available by default in Unix/Linux based operating systems.
The practical examples throughout this guide will show you how to use the touch command.
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 Xfce 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.

I have this server to set to automatically perform a ‘yum update -y’ once every 24 hours in order to keep it automatically up to date. After the most recent MariaDB update to version 10.0.29-1.el7.centos in CentOS 7.3 I found that it failed to start back up correctly, here’s how to fix it.
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.
Recently while rebooting the web server that hosts this website in order to perform a kernel update I ran into a kernel panic on boot.
Amazon Web Services (AWS) do not seem to provide an interactive console for Elastic Compute Cloud (EC2) instances, so I had to work out another way to fix the problem which I have documented here.
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.
DNF is the next major verison of Yum and as such it aims to maintain CLI compatibility with Yum, so a lot of the information here will be similar to our yum commands.
Like Yum, DNF is quite powerful as it’s capable of automatically resolving dependency issues, and is similar to other package managers such as ‘apt-get’ in Debian based distributions.
These examples should serve as a useful introduction, guide or cheat sheet style resource for how to use the dnf command in Linux.
In December 2016 Microsoft made their SQL Server database available in Linux. Here we’ll cover how to install and perform basic setup of MSSQL in the RHEL based Linux distribution CentOS.
