Installing CentOS, a free RedHat derived well supported distirbution
Related [ edit ]
CentOS is a free source code compatible fork of Red Hat Enterprise Linux (RHEL), with only certain branding and other minor differences.
Unlike RHEL, there is no official support, however the open source community provides extensive online documentation for installing, configuring, and managing CentOS.
As of 2021 a new variant called CentOS Stream is emerging that has a slightly different relationship with RHEL. Whereas each CentOS version has been a repackaging of RHEL release, CentOS Stream will be a distribution that is just upstream of its RHEL counterpart. Some have suggested that this may lessen the stability of CentOS Stream, while others have suggested more timely updates and package support than notoriously glacial pace RHEL updates.
