The CentOS community downloads all the source code on the Redhat website and recompiles it. Because AS/ES/WS is a commercial product, you must change all Redhat logos and logos to your own CentOS logos. For example, after compiling the original SRPM source code of AS4.0 and replacing it with the logo of the Centos community, it became CentOS4.0. After the source code of RedhatEnterpriseLinuxAS4Update1 is compiled, the CentOS4.1 CentOS community downloads all the source code on the Redhat website and re-compiles it. Because AS/ES/WS is a commercial product, you must change all Redhat logos and logos to your own CentOS logos. For example, after compiling the original SRPM source code of AS4.0 and replacing it with the logo of the Centos community, it became CentOS 4.0. After the source code of Redhat Enterprise Linux AS4 Update1 is compiled, it becomes CentOS4.1. After the source code of AS4 Update2 is compiled, it becomes CentOS4.2. This is how CentOS is generated.
Therefore, CentOS is the free version of Redhat AS/ES/WS. centos provides the same features and performance AS redhat Enterprise linux. At the same time, centos also provides free long-term upgrade and update services. Therefore, among the many clone versions of RHEL, CentOS is outstanding.
Although centos is a RHEL clone, it is not exactly the same. it is 100% interchangeable. For centos, the RHEL software does not guarantee 100% normal operation on CentOS.
