Ubuntu Linux

Based on the Debian distribution, Ubuntu has become a widely used operating system. Managed by Canonical Ltd., it has been around for over two decades. There is excellent support from Canonical through documentation and forums, and for a fee you can procure additional technical support. This makes the distribution a viable option for commercial operations. Ubuntu comes in many variants including: Server, Desktop, Long Term Support (LTS), and many more. It is wise to become familiar with this operating system for enthusiasts and professional alike.

Red Hat Enterprise Linux

This distribution of Linux started life as the Red Hat Linux project and was at one time the most popular distribution. In 2003 is became Red Hat Enterprise Linux (RHEL). Its mainly focused on the business world, as such it typically requires the purchase of a license . In return they offer a support to their customers.

RHEL is required to release their source code. Previously this was most commonly done through the Community Enterprise Operating System (CentOS). However this project has changed direction. At this time, Rocky Linux is the likely the best option to learn or operate on the source code of RHEL.

Rocky Linux

The Rocky OS is based on the enterprise Linux offering of Red Hat. It was created after CentOS became a front runner to Red Hat Enterprise Linux (RHEL). Anyone looking for a near exact experience of RHEL can use this operating system. It is particularly valuable when working on programs made for Red Hat. Additionally, it is a great option for those studying for the CompTIA Linux+ exam.

Install Guest Editions on CentOS Linux

Installing CentOS Linux in a virtual machine with VirtualBox is a straightforward exercise. The exception comes when configuring Guest Editions on the operating system. I find it easiest to use a group install with Yum, before “inserting” the disc for Guest Editions. Using the following two lines in the shell will ensure that the C compiler and kernel are available for installing Guest Editions.

sudo yum groups install 'Development Tools'
sudo yum install kernel-devel-yourLatestVersion

Further guidance is available in the user manual. https://www.virtualbox.org/manual/UserManual.html#externalkernelmodules

Community Enterprise Operating System (CentOS) is an open-source operating system that is functionally the same as Red Hat Enterprise Linux (RHEL). The product has transitioned from being the downstream source code of RHEL, to the new CentOS Stream. CentOS Stream is a “stable” precursor to RHEL.

End of Life (EOL) for CentOS 7 is June 30, 2024.
