We are pleased to announce the immediate availability of CentOS Linux
6.7 and install media for i386 and x86_64 Architectures. Release Notes
for 6.7 are available at
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.7 - we recommend
everyone review these release notes.
CentOS Linux 6.7 is derived from source code released by Red Hat, Inc.
for Red Hat Enterprise Linux 6.7. 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. All of our testing is only done against this
There are many fundamental changes in this release, compared with the
past CentOS Linux 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 6.7 release are also on the CentOS
mirrors as zero day updates. When installing CentOS-6.7 (or any other
version) from any of our media, you should always run 'yum update'
after the install to apply these.
Users consuming our centos-cr repositories will already be running all
the packages that make up CentOS-6.7, and all updates released since.
They will notice only the centos-release rpm update today when moving
to CentOS Linux 6.7. 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,
Upgrading from CentOS-6.0 / 6.1 / 6.2 / 6.3 / 6.4 / 6.5 or 6.6
CentOS Linux 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 Linux 6.x release to 6.7.
We also test this in our QA cycles and have noticed no problems, any
issues would be mentioned in the Release Notes.
Downloading CentOS Linux 6.7 for new installs:
When possible, consider using torrents to obtain our ISOs. Usually it
is also the fastest means to download the distro.
The install media is split into various formats. We have made efforts
to ensure that most install types and roles can be done from DVD-1
itself, and the minimal install ISO is only tested to deliver a
minimal install set, when used as an ISO format ( either on cd or usb
). While other forms of installs ( eg. pxe delivered ) might work from
the minimal ISO, they are neither tested not supported. The only
format where we support the entire set of install options and delivery
mechanisms is via the complete CentOS Linux 6.7 tree, wihch can also
be created by consolidating all content from DVD1 and DVD2.
We no longer produce CD size images for the entire CentOS Linux 6
distribution, however the minimal install and netinstall iso images
are small enough to fit on all CD grade media.
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 http://www.centos.org/download/mirrors/ Most mirrors will
allow downloads over http, ftp and rsync.
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
sha1sum for the CentOS-6.7 ISOS:
Images for various on-premise and off-premise Cloud environments are
currently under development for CentOS Linux 6.7 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-devel list where such
issues are discussed (
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.
If you have questions you would like to field at us in real time, come
join the office hours on Wed or Thu of every week. You can find
details on these at http://wiki.centos.org/OfficeHours
Meet-ups and Events:
If you would like to get involved in helping organize, run, present or
sponsor a CentOS Dojo or even just want more details then join the
CentOS Promo list:
http://lists.centos.org/mailman/listinfo/centos-promo and drop an
email introducing yourself. We are very keen to find help to run
events around the world, and also to find people who can represent
CentOS at various community events around the world.
Contributing and joining the project:
We are always looking for people to join and help with various things
in the project. If you are keen to help out a good place to start is
the wiki page at http://wiki.centos.org/Contribute . If you have
questions or a specific area you would like to contribute towards that
is not covered on that page, feel free to drop in on #centos-devel at
irc.freenode.net for a chat or email the centos-devel list
Thanks to everyone who contributed towards making CentOS Linux 6.7,
especially the effort put in, as always, by the QA
(http://wiki.centos.org/QaGroup) and Build teams.
A special shout out to all the donors who have contributed hardware,
network connectivity, hosting and resources over the years. The CentOS
project now has a fairly well setup resource pool, solely thanks to
