CentOS

CentOS is an enterprise Linux distribution based on the sources from Red Hat Enterprise Linux. CentOS conforms with Red Hat's redistribution policy and aims to be 100% binary compatible. Each CentOS version is supported for 7 years (by means of security updates). A new CentOS version is released every 2 years and each CentOS version is regularly updated (every 6 months) to support newer hardware. Currently, there are 4 different supported CentOS releases: CentOS-5 is based on Red Hat Enterprise Linux 5, CentOS-4 is based on RHEL4, CentOS-3 is based on RHEL3, and CentOS-2 is based on RHAS2.1.

A lightweight server edition and a minimal installation CD will be published.

        Release Notes: This release has bugfixes, feature enhancements, and new hardware support. There are no new ISO images for this release. Installs moving forward will be off the 4.8 media and an upgrade will move you from version 4.8 to version 4.9. This is done to maintain compatibility with third party kernel drivers, which are designed to be installed as part of the installation process.

        •  16 May 2010 15:58

          Release Notes: OpenOffice.org has been updated to version 3.1.1, Samba3x is available in version 3.3.8, PostgreSQL84 in version 8.4, and there is a release of Freeradius2. The latter three aren't installed by default, but they can be used to upgrade from the still included older versions of these packages. Other upgrades include a newer version of the wireless drivers suite, including the ath9k and iwlwifi drivers. GDB, Valgrind, and SystemTap also have been updated. The Live CD has been released in version 5.5 to reflect these changes.

          •  25 Oct 2009 17:03

            Release Notes: This release adds KVM as a technology preview for virtualization, and extends the number of supported file systems, as XFS is supported in the 64-bit release. FUSE support has been added to the base distribution. ext4 (still as a technology preview) has been updated. On the desktop side, the rebase of ALSA is the most noteworthy change. For developers, version 4.4 of gcc is available. For the first time, the LiveCD has been released at the same time as the corresponding point release of CentOS. From now on, the Live CD will no longer be announced as a separate release.

            build5 includes a fully configured yum installed by default, with the addons repository already there.

            a great alternative
            If you're not down with the contractual obligations that RHEL would hold you to, CentOS is a great way to have a long-term stable Enterprise Linux distribution without the extra baggage. It's RHEL 3 without the Red Hat trademarks or mandatory support contract. So feel free to burn copies for your friends and distribute at LUG meetings and installfests. It's ideal for corporate use because updates will be available for five years and patches will address stability and security issues only.

            However, for those who want extra functionality, add three lines to /etc/yum.conf to include the "addons" repository and you'll get some newer things (that are still good & stable, but not included with RHEL).

            We've switched to this at $WORK after Red Hat shook things up late in 2003 and haven't looked back. Our major Linux support vendors have agreed to support CentOS, for the most part. This is because it is essentially a technical clone of RHEL and since they're already supporting that anyway there is no added cost to them to support it.

            So essentially this has the nuts and bolts of RHEL with the community conscience of a Debian-like social contract.
