CentOS
CentOS
Reliable, community-driven Linux for consistent, secure computing experiences.
CentOS Linux is a community-supported distribution that leverages resources provided publicly through Red Hat and CentOS repositories, specifically designed for Red Hat Enterprise Linux (RHEL). The main objective of CentOS is to preserve functional compatibility with RHEL, while the CentOS Project emphasizes the modification of packages to remove any branding or visual identifiers from the upstream vendor. Available at no charge, CentOS can be freely shared and redistributed by users. Each CentOS version is backed by support until the related RHEL version concludes its general support lifecycle. New CentOS versions are typically released after the rebuilding of new RHEL versions, occurring approximately every 6 to 12 months for minor updates and extending over several years for major releases. The rebuild process can take anywhere from a few weeks for minor updates to several months for significant changes, ensuring timely availability of new features. This structured approach allows users to enjoy a secure, reliable, and easily manageable Linux environment that is consistent and reproducible, ultimately nurturing a robust community around its usage and development. Additionally, the emphasis on community involvement encourages collaboration and innovation among users and developers alike.
