This short guide will show you how to upgrade MariaDB 10.0 to 10.1 in CentOS 7 Linux. We’ll start by modifying the repository file and perform a ‘yum update’. This may fail to automatically update the MariaDB-server package, so we’ll show you how to manually use the mysql_upgrade script to complete the process.
There are many different supported versions of Red Hat Enterprise Linux (RHEL)/CentOS Linux available for use, so which version of CentOS/RHEL Linux should you be using?
Here we take a look at the differences between the different versions of CentOS and compare them to help you decide on the best version to use.
This tutorial will walk you through opening a port in the default firewall in CentOS 7, firewalld.
You will see that while we can manually open a specific port, it is often easier and beneficial to allow based on predefined services instead.
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 MATE desktop environment in 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.
By default in CentOS 7 minimal the ifconfig command is not available, and for good reason, it’s considered deprecated and has been replaced by the ip command.
Regardless, if you really can’t get by without ifconfig, here’s how you can install it.
This WordPress based website loads fairly quickly, or at least I’d like to think so based on my testing. In this post I’m going to share some of the things that I’ve setup in order to get the fastest possible page loads from WordPress.
We’ll be covering general server configuration, Nginx web server configuration, WordPress plugin configuration, and finally use of content distribution networks.
Are you used to the classic iptables firewall and want to kill firewalld? Well there’s still hope for you yet! Here we will show you how to stop and disable the default firewalld firewall and instead install and configure iptables in CentOS 7 Linux.
The routing table is used to show you where various different network subnets will be routed to. Here are three different commands that you can use to print out the routing table in Linux.
In most cases Windows desktops or servers will typically be joined to a Windows domain controller running Microsoft’s Active Directory, however this is not the only option.
It is possible to join Windows to a FreeIPA realm and then log into the Windows computer with an account from FreeIPA as it makes use of Kerberos for single sign on (SSO). FreeIPA is an open-source project sponsored by Red Hat, which attempts to provide similar functionality to Active Directory for Linux and Unix systems.
This may be a good option if you already run a large Linux or Unix environment, but need to have a small amount of Windows servers capable of using the same centrally managed user accounts.
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 Cinnamon 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.
