CentOS Overview

CentOS Overview

CentOS is an Enterprise-class Linux Distribution derived from sources freely provided to the public by a prominent North American Enterprise Linux vendor.  CentOS conforms fully with the upstream vendors redistribution policy and aims to be 100% binary compatible. (CentOS mainly changes packages to remove upstream vendor branding and artwork.)  CentOS is free.

CentOS is developed by a small but growing team of core developers.  In turn the core developers are supported by an active user community including system administrators, network administrators, enterprise users, managers, core Linux contributors and Linux enthusiasts from around the world.

CentOS has numerous advantages over some of the other clone projects including:  an active and growing user community, quickly rebuilt, tested, and QA'ed errata packages, an extensive mirror network, developers who are contactable and responsive, multiple free support avenues including IRC Chat, Mailing Lists, Forums, a dynamic FAQ.  Commercial support is offered via a number of vendors.

The single CD server install for CentOS 4.7 / i386 has now been released and is available from all active mirrors. The ISO is available on  bit-torrent, via the torrent file : http://mirror.centos.org/centos/4/isos/i386/CentOS-4.7.ServerCD-i386.torrent  Sha1sum for the torrent file is: 779adf04b554ee01d05520936bb406a16a85d45c  md5sum for the CentOS 4.7 ServerCD / i386 is : 429c3c5d627682d5d9e8084c8e5456cd  CentOS-4.7.ServerCD-i386.iso  sha1sum for the CentOS 4.7 ServerCD / i386 is: 6272d724f0abb95d2a5652724fe6b3740706d543  CentOS-4.7.ServerCD-i386.iso  You can find a local mirror to download from here:  http://isoredirect.centos.org/centos/4/isos/i386/  --------------------------------------------------------------------- We appreciate all feedback, including RFE's and bug notifications.  Notes:  1. This installer will only work with i686 based cpu's ( no K6, older Via C2 / C3 support )  2. The included packages are a subset of all packages available in the CentOS distribution, however yum has been pre-configured to use the entire repository.  3. In order to ensure that drivers and other third party apps maintain compatibility, the package set used on the Server CD is from Release time CentOS 4.7, you are strongly encouraged to run a 'yum update' immediately after installation.  4. As some of you will notice, the iso size is lower than the 650mb acceptable for a single CD. Feedback on what other packages should be aded or removed from this Single CD for the next release are very welcome.
