How to install Rocky Linux 8

Rocky Linux is an open-source enterprise OS designed to be “100% bug-for-bug” compatible with RHEL. It is helpful on both servers and workstations. It was created to replace CentOS, as RedHat has discontinued it.

Rocky Linux 8 works well on both servers and workstations. So if you’re itching to try out the latest release, follow this guide, and we’ll show you how to install Rocky Linux 8 on your system.

Downloading Rocky Linux 8

Rocky Linux is downloadable in two editions: Minimal and DVD. Each ISO has strengths and weaknesses. However, both of them deliver the same core Rocky Linux experience.

The Minimal edition, once installed, gives you a bare, command-line only installation of Rocky Linux 8, which is excellent for those who don’t need a lot of packages. On the other hand, the DVD release offers many packages and is the best way to go if you plan to use Rocky as a workstation OS or want to install many applications on your server OS.

Decide what edition works for you by heading over to rockylinux.org/download. Additionally, it is possible to download a Boot ISO, which is helpful, though, it will not be covered in this guide.
