What is Rocky Linux?

Rocky Linux is a Linux distribution developed by Rocky Enterprise Software Foundation. It is intended to be a downstream, complete binary-compatible release using the Red Hat Enterprise Linux (RHEL) operating system source code. The project’s aim is to provide a community-supported, production-grade enterprise operating system. Rocky Linux, along with Red Hat Enterprise Linux and SUSE Linux Enterprise, has become popular for enterprise operating system use.

Rocky Linux 9.0, the latest version of the open source enterprise operating system designed to be fully bug-for-bug compatible with Red Hat Enterprise Linux (RHEL), is now generally available. The update includes new security and networking features, and a new open source build system called Peridot.

Released on 14 July 2022, Rocky Linux 9.0 has all of the build chain infrastructure tools for developers to pick up Rocky Linux or extend or reproduce the Operating system, should a developer want to do something independently of the community or any upstream supporting organization. A primary goal behind developing the new, cloud-native build system was assuring that new versions of Rocky can be released within one week of new RHEL version releases.
