We are pleased to announce the immediate availability of CentOS-6.6 and install media for i386 and x86_64 Architectures. Release Notes for 6.6
are available at http://wiki.CentOS.org/Manuals/ReleaseNotes/CentOS6.6 –
we recommend everyone review these release notes.
CentOS-6.6 is based on source code released by Red Hat, Inc. for Red Hat Enterprise Linux. All upstream variants have been placed into one combined repository to make it easier for end users. Workstation, server, and minimal installs can all be done from our combined repository.
There are many fundamental changes in this release, compared with the past CentOS-6 releases, and we highly recommend everyone study the upstream Release Notes as well as the upstream Technical Notes about the changes and how they might impact your installation. (See the ‘Further Reading’
section if the CentOS release notes link above).
All updates since the upstream 6.6 release are also on the CentOS-6.6
mirrors as zero day updates. When installing CentOS-6.6 (or any other version)
from any of our media, you should always run ‘yum update’ after the install.
Users consuming our CentOS-cr repositories will already be running all the packages that make up CentOS-6.6 as of one week ago and will notice only the CentOS-release rpm update today. For more information on the CR repository for future updates, see this link:
Release Announcements for all updated packages are available here:
Upgrading From Prior Major CentOS Versions:
We recommend everyone perform a fresh reinstall rather than attempt an in place upgrade from other major CentOS versions (CentOS-2.1, CentOS-3.x, CentOS-4.x, CentOS-5.x).
Upgrading from CentOS-6.0 / 6.1 / 6.2 / 6.3 / 6.4 or 6.5
CentOS is designed to automatically upgrade between releases within a major version (in this case, CentOS-6). Unless you have edited your yum default configuration, a ‘yum update’ should move your machines seamlessly from any previous CentOS-6.x release to CentOS-6.6.
Downloading CentOS-6.6 for new installs:
When possible, consider using torrents to obtain our ISOs. Usually it is also the fastest means to download the distro.
Torrent files for the DVD’s are available at :
You can also use a mirror close to you to get any of our ISOs:
If you need to update a local mirror, you can choose from our mirror network:
Most mirrors will allow downloads over http, ftp and rsync.
Please keep in mind that not all mirrors are currently updated, some may take as long as 24 hours after this announcement to receive all CentOS-6.6
We have made efforts to ensure that most install types and roles can be done from DVD-1 itself.
Note: Some UEFI machines can not use the ‘netinstall’ ISOs, but either the DVD or minimal ISOs will work with UEFI. Secure Boot must be disabled to install CentOS-6.6.

Images for various on-premise and off-premise Cloud environments are currently under development for CentOS-6.6 and will be released in the coming days. Everyone looking to join and help with the CentOS Cloud efforts is encouraged to join the CentOS-Virt list where such issues are discussed ( http://lists.CentOS.org/mailman/listinfo/CentOS-virt ).
The best place to start when looking for help with CentOS is at the wiki
( http://wiki.CentOS.org/GettingHelp ) which lists various options and communities who might be able to help. If you think there is a bug in the system, do report it at http://bugs.CentOS.org/ – but keep in mind that the bugs system is *not* a support mechanism. If you need supported software with Support Level Agreements, people to call and response times then we recommend Red Hat Enterprise Linux.
