Website and documentation
Website
The Linux website is available at the following URL: https://linux.cern.ch
CERN Documentation
The website contains all the end-user documentation, and we will extensively use it for the exercices during this tutorial.
It contains up-to-date information about the lifecycle of distributions at CERN and the future plans.
Weekly updates are documented with links to relevant Red Hat reports if available.
Red Hat documentation
Given that both CentOS and AlmaLinux are derivatives of Red Hat Enterprise Linux (RHEL), the documentation pertaining to all three operating systems exhibits significant similarities. As a consequence, the RHEL documentation assumes particular relevance, serving as a valuable resource for users and administrators of these systems. It provides a wealth of information that's directly applicable to CentOS and AlmaLinux, given their shared lineage with RHEL.
Red Hat provides documentation for every released product :
- RHEL7 (Red Hat Enterprise Linux 7)
- RHEL8 (Red Hat Enterprise Linux 8)
- RHEL9 (Red Hat Enterprise Linux 9)
The Red Hat documentation is very useful to deep dive in specific parts of the system and is very well organised around topics (Installation, System administration, tuning, etc...)
