CentOS (Community Enterprise Operating System, Chinese means community enterprise operating system) is an enterprise-level Linux distribution based on Red Hat Linux that can freely use source code.
Because it comes from the same source code, some servers that require high stability use CentOS instead of the commercial version of Red Hat Enterprise Linux. The difference between the two is that CentOS is completely open source.
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.
