CentOS (Community Enterprise Operating System) is a free, open-source Linux distribution derived from the sources of Red Hat Enterprise Linux (RHEL). It is widely used in enterprise environments, web hosting, and server deployments due to its stability, security, and long-term support.

2. Free & Open Source:

  • No licensing costs, making it popular for businesses and developers.

3. Long-Term Support (LTS):

  • CentOS 7 (released 2014) was supported until June 30, 2024.
  • CentOS 8 (released 2019) had a shortened lifecycle, with official support ending in December 31, 2021.

4. Binary Compatibility with RHEL:

  • Most software compiled for RHEL works seamlessly on CentOS.

5. Security-Focused:

  • Regular security updates and a minimal attack surface.
  • CentOS Alternative Projects: Rocky Linux: A community-driven, 1:1 binary-compatible replacement for CentOS. AlmaLinux: Another RHEL-compatible distro created by the original CentOS founders. Oracle Linux: Provides similar compatibility with RHEL (some enterprises prefer it).
