Release for CentOS-5.4 i386 and x86_64
Posted on: 10/22/2009 02:21 PM

CentOS-5.4 for i386 and x86_64 Architectures has been released:

CentOS-5.4 is based on the upstream release EL 5.4.0, and includes packages from all variants including Server and Client. All upstream repositories have been combined into one, to make it easier for end users to work with. And the option to further enable external repositories at install time is now available in the installer.

This is just an announcement email, not the release notes. The Release Notes for CentOS-5.4 can be found on-line at : and everyone is encouraged to look through them once. Also worth browsing through at the CentOS FAQ's at

Upgrading from CentOS-5.3 ( or CentOS-5.0 / 5.1 / 5.2 ):

If you are already running CentOS-5.3 or an older CentOS-5 distro, all you need to do is update your machine via yum by running :

'yum update'

Running 'yum list updates' before doing the update is recommended, so you can get a list of packages that are going to be updated. To check you are indeed on CentOS-5.4, run : 'rpm -q centos-release' and that should return: 'centos-release-5-4.el5.centos.1'

LiveCD i386

For the first time, we are also releasing the i386 CentOS-5.4 LiveCD at the same time as the main distro. There will be a separate announcement with details of changes in the 5.4 LiveCD

LiveCD x86_64

Also for the first time, we now have a x86_64 CentOS LiveCD. This release includes support for both 64bit and 32bit user-space. However, due to size issues will only burn to a large capacity CD-r. There will be a separate announcement with details for the x86_64 LiveCD.

Downloading CentOS-5.4 for new installs:

When possible, consider using torrents to run the downloads. Not only does it help the community and keeps mirrors from running up high bandwidth bills, in most cases you will find its also the fastest means to download the distro. There are present over three hundred people seeding CentOS-5 and its possible to get upto 100mbps downloads via these torrents.

-- Via direct download:
Due to bandwidth considerations the CentOS Project does not publish ISOS directly from our network machines. However direct downloads are available from external mirrors over http, ftp and rsync, and a geoip based list is available at to give you the best predictable match ( and only lists mirrors that are updated already, so you don't need to waste time looking for a sync'd mirror )

Some mirrors also publish DVD images that can be downloaded directly. Refer to the mirrors list page at for more details Mirrors that offer DVD's are clearly marked on the page.

Outstanding Updates:

Since upstream released their 5.4 media, a series of updates have been issued. All these pending updates for CentOS-5.4 will be released over the next 48 to 96 hours to be complete by Monday, 26th Oct 2009.

Starting with 5.4, we will also have all fast-track rpms from upstream available in the fasttrack repository hosted at This will start getting packages in the next few weeks, and also means that we will be able to move towards having a functional yum-security setup in place. Details on these will be posted by the 15th of Nov 2009.

Sources and Debuginfo packages:

srpms and debuginfo packages are still making their way to the centos mirrors and should be online within the next few days. Most sources are already in place, while the debuginfos are only stating to get uploaded now.

Getting Help:

The best place to start when looking for help with CentOS is at the wiki ( ) 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 - but keep in mind that the bugs system is *not* a support mechanism.

Some Friendly URL's :

A big thanks to everyone who contributed, including the translation teams, the qa team, the artwork team, the CentOS Developers and all the users out there.

Enjoy this release, tell all your friends about it too!
