Introduction
CentOS is an enterprise-level Linux distribution based on Red Hat Linux with freely available source code. Each version of CentOS is supported (via security updates) for ten years. New versions of CentOS are released approximately every two years, and each version of CentOS is updated regularly (approximately every six months) to support new hardware. In this way, a secure, low-maintenance, stable, highly predictable, and highly repeatable Linux environment is established. CentOS is the abbreviation of Community Enterprise Operating System.
CentOS is the product of recompilation of RHEL (Red Hat Enterprise Linux) source code, and many known bugs have been corrected on the basis of RHEL. Compared with other Linux distributions, its stability is trustworthy.
CentOS announced in early 2014 that it would join Red Hat.
What remains unchanged after CentOS joins Red Hat is:
1. CentOS continues to be free of charge
2. The sponsored content-driven network center remains unchanged
3. Bug, Issue and emergency handling strategies remain unchanged
4. Red Hat Enterprise Linux and CentOS firewalls also still exist
The changes are:
1. We Work for Red Hat, not RHEL
2. Red Hat provides sponsorship of build systems and initial content distribution resources
3. Some development resources including source code will be easier to obtain
4. Avoided some legal issues with Red Hat
