It exists to provide a free enterprise class computing platform and strives to maintain 100% with its distribution. CentOS stands for Community ENTerprise Operating System. Contents.StructureRed Hat Enterprise Linux is available only through a paid subscription service that provides access to software updates and varying levels of technical support.
The product is largely composed of software packages distributed under, and the for these packages is made public by Red Hat.CentOS developers use Red Hat's source code to create a final product very similar to Red Hat Enterprise Linux. Red Hat's branding and logos are changed because does not allow them to be redistributed.CentOS is available free of charge. Technical support is primarily provided by the community via official mailing lists, web forums, and chat rooms. The project is not affiliated with Red Hat and thus receives no financial or logistical support from the company; instead, the CentOS Project relies on donations from users and organizational sponsors. Versioning schemeCentOS version numbers have two parts, a major version and a minor version. The major and minor version numbers respectively correspond to the major version and update set of Red Hat Enterprise Linux from which the source packages used to build CentOS are taken. For example, CentOS 4.4 is built from the source packages from Red Hat Enterprise Linux 4 update 4.Since mid-2006, starting with version 4.4 (formerly known as Red Hat Enterprise Linux 4.0 update 4), Red Hat has adopted a versioning convention identical to that of CentOS, e.g., Red Hat Enterprise Linux 4.5.
Release historyThe architecture information is taken from the page. See also:Tao Linux was another prominent distribution derived from Red Hat Enterprise Linux.
Its primary developer announced in June 2006 that Tao would be retired and rolled into CentOS development. Migration via 'yum update' was available to Tao users, providing a relatively painless migration path to the CentOS release. This helped prevent Tao users from becoming 'orphaned' by their OS.
Organizational DifficultiesIn July of 2009, it was reported that CentOS's founder, 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 of 2009, the CentOS team reportedly made contact with Davis and obtained the centos.info and centos.org domains. CentOS Project.
