What is the relationship between CentOS and Liunx?

Liunx has three major releases: Slackware, debian, and redhat. Centos is one of multiple releases of liunx. Redhat has a paid commercial version and a free open-source version. The commercial version is called the RHEL (RedHat Enterprise Linux) series, and this CentOS (Community ENTerprise Operating System) the source code is compiled by RHEL according to the open source code. CentOS can be used instead of RHEL for commercial use. The difference between the two lies in that CentOS does not contain closed source code software, that is, it is free.

What is the relationship between CentOS and RHLR?

There are two methods for RHEL release. One is the binary distribution method, and the other is the source code distribution method.
No matter which release method you use, you can obtain it for free (for example, download it from the Internet) and release it again. However, if you use their online upgrades (including patches) or consulting services, you must pay for them.

RHEL has always provided source code distribution methods. CentOS is to re-compile the source code released by RHEL to form a usable binary version. Since the LINUX source code is GNU, it is valid from obtaining the RHEL source code to compiling a new binary. Only REDHAT is a trademark, so the trademark of REDHAT must be removed from the new release. REDHAT's attitude towards this release is: "We don't really oppose this release. Users who actually pay for it do not pay attention to the system itself, but the commercial services we provide." Therefore, CentOS can obtain all RHEL functions and even better software. However, CentOS does not provide commercial support to users, and of course it is not subject to any commercial responsibilities.
