The best thing about open source, and one of the reasons why I love the entire Linux ecosystem, is choice. With open source software you have the ability to choose what OS or software you run, how you run it, and what you can do with it. If you don’t like the decisions that have […]
Tag: RHEL
In this post I wanted to demonstrate converting from one of the RHEL compatible Enterprise Linux distributions, like CentOS, Rocky Linux or Oracle Linux, to Red Hat Enterprise Linux. I’ll be demonstrating from an Oracle Linux server running in Proxmox, however these steps will work regardless of the RHEL compatible distribution you are starting from […]

Exploring OpenShift
OpenShift is Red Hat’s container orchestration platform built on top of Kubernetes. I love working with containers and Kubernetes, and as I’m also a big fan of Red Hat technologies I wanted to become more familiar with working with OpenShift. I’ve also been studying Red Hat’s Openshift training courses including OpenShift Developer and OpenShift Administrator, […]
Recently I’ve been working on an Ansible upgrade project that included building out an Ansible Automation Platform installation and upgrading legacy ansible code to modern standards. The ansible code that we were working with had been written mostly targeting Enterprise Linux versions 6 and 7 and was using pre ansible version 2.9 coding standards. The […]
Previously I discussed deploying Enterprise Linux in AWS which I demonstrated by using the AWS console. This is a common way to deploy servers to the cloud, however doing server deployments manually can create a situation where you’re stuck with static images that are difficult to replicate when your infrastructure grows. One of the benefits […]

Deploying Enterprise Linux in AWS
In a previous post I discussed installing Enterprise Linux in a virtual machine, this time I wanted to write about deploying a server to the cloud. Cloud Computing platforms like Amazon’s AWS allow you to build and run all kinds of Infrastructure and services on-demand without having to purchase and maintain expensive physical computing hardware. […]
Previously I wrote about using Ansible to manage the configuration of Linux servers. I love using Ansible and use it almost every day, however in a large Enterprise environment with multiple users and a lot of Ansible roles and playbooks, sometimes using Ansible on its own becomes difficult to maintain. In this post I’m going […]
In this post I’ll outline the steps to join an Enterprise Linux host to Microsoft Active Directory for user account management. Why would you want to do this? In an Enterprise environment it’s common to have a mix of Windows and Unix/Linux machines that offer different services across the organisation. To resolve the issues of […]

Installing Enterprise Linux
In this post I’m going to demonstrate the installation of Enterprise Linux in a Virtual lab environment. I’ll be installing both Red Hat Enterprise Linux 9, because it’s the leading Enterprise Linux distribution, and CentOS Stream 9, because it’s the upstream community release of RHEL. The steps outlined here should be the same for all […]
