Introduction to Rocky Linux
As we discussed in our future of CentOS article last month there is a huge amount of interest in many up and coming Linux distributions since the announcement by Redhat that CentOS would switch to an upstream release of RHEL rather than downstream. In this article we are going to look at Rocky Linux which is intended as a drop in replacement for CentOS. Unlike Almalinux there is currently no production release available for Rocky Linux however there is a release candidate available which we have tested and installed on our servers.
What is RockyLinux?
Key features of RockyLinux
You can view the full list on their site, but here are our favourite features:
- Completely free and open source with community support
- 100% Binary compatible with RHEL so all your favourite packages will install and run out the box
- Future in place conversion available for CentOS
- Years of support planned for releases
- Founded by original CentOS founder Gregory Kurtzer
Our Impressions of RockyLinux
You can find Rocky Linux available on our high speed 10Gb UK Mirror where .iso images are available for both x86-64 and ARM processors. With “Minimal”, “DVD”, and “Boot” options.
Installation of RockyLinux is very similar to CentOS and other RHEL distributions and should look familiar to most. The installer will take you through partioning, keyboard layout, package selection etc. The installer is graphical based even when using the minimal installation image.
Upon booting the operating system you are taken to a login prompt with an ASCII art version of the Rocky Linux logo. As at the time of writing only the release candidate is available and you are instructed not to use this in a production enviroment!
Web Based Interface
One of the features of RockyLinux that we really like is the web based interface that is installed as default. It allows you to easily configure your system if you aren’t comfortable using shell and also features a built in web based terminal. Whilst there is limited options currently available via this interface we expect it is something that we be built on over time.
