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.
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.
In this post we will cover how to install and configure Windows Server Update Services (WSUS) in Microsoft’s Windows Server 2016.
WSUS can be used to automatically download Windows update files and store them locally. Other Windows servers in your network will then download the updates from the WSUS server rather than the Internet, saving you Internet bandwidth and speeding up the Windows update process.
With WSUS we can configure all of our servers to be automatically updated, ensuring that security updates are installed quickly from a central location. This will provide us with useful information such as reports advising which servers have or have not been patched with a specific update.
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.
