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.
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.
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.
In this post we will show you how to use group policy to configure computers within an Active Directory domain to perform automatic Windows updates from either the Internet or a WSUS server that you manage.
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.
This post will cover how to create and manage computer groups in Windows Server Update Services (WSUS) for Windows Server 2016.
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.
