CentOS
CentOS (/ˈsɛntɒs/, from Community Enterprise Operating System; also known as CentOS Linux) is a discontinued Linux distribution that provided a free and open-source community-supported computing platform, functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board.
The first CentOS release in May 2004, numbered as CentOS version 2, was forked from RHEL version 2.1AS. Since version 8, CentOS officially supports the x86-64, ARM64, and POWER8 architectures, and releases up to version 6 also supported the IA-32 architecture. As of December 2015[update], AltArch releases of CentOS 7 are available for the IA-32 architecture, Power ISA, and for the ARMv7hl and AArch64 variants of the ARM architecture. CentOS 8 was released on 24 September 2019.
In December 2020, Red Hat unilaterally terminated CentOS development in favor of CentOS Stream 9, a distribution positioned upstream of RHEL. In March 2021, CloudLinux (makers of CloudLinux OS) released a RHEL derivative called AlmaLinux. Later in May 2021, one of the CentOS founders (Gregory Kurtzer) created the competing Rocky Linux project as a successor to the original mission of CentOS.
CentOS originated as a build of CAOS Linux, an RPM-based Linux distribution started by Gregory Kurtzer in 2002. Infiscale described its GravityOS as "[including] the small footprint of Caos", indicating a certain level of influence from the discontinued distribution.
In June 2006, David Parsley, the primary developer of Tao Linux (another RHEL clone), announced the retirement of Tao Linux and its rolling into CentOS development. Tao users migrated to the CentOS release via yum update.
In July 2009, it was reported in an open letter on the CentOS Project web site that one of CentOS's founders, Lance Davis, had disappeared in 2008. Davis had ceased contribution to the project, but continued to hold the registration for the CentOS domain and PayPal account. In August 2009, the CentOS team reportedly made contact with Davis and obtained the centos.info and centos.org domains.
In July 2010, CentOS overtook Debian to become the most popular Linux distribution for web servers, with almost 30% of all Linux web servers using it. Debian retook the lead in January 2012.
In January 2014, Red Hat announced that it would sponsor the CentOS Project, "helping to establish a platform well-suited to the needs of open source developers that integrate technologies in and around the operating system". As a result of these changes, ownership of CentOS trademarks was transferred to Red Hat, which now employs most of the CentOS head developers; however, they work as part of Red Hat's Open Source and Standards team, which operates separately from the Red Hat Enterprise Linux team. A new CentOS governing board was also established.
