What is CentOS?
CentOS is 100% compatible rebuild of the Red Hat Enterprise Linux, in full compliance with Red Hat’s redistribution requirements. CentOS is for people who need an enterprise class operating system stability without the cost of certification and support.
Following the release of RHEL 5.4, CentOS 5.4 has just hit the CentOS mirrors. Time to update the Local CentOS YUM repository script.
Adding CentOS 5.4 to the YUM repository script
Create the following additional Directories for CentOS 5.4:
# mkdir -p /var/www/html/centos/5.4/os/i386
# mkdir -p /var/www/html/centos/5.4/updates/i386
# mkdir -p /var/www/html/centos/5.4/os/x86_64
# mkdir -p /var/www/html/centos/5.4/updates/x86_64
Add the CentOS 5.4 repository to the bash script which will rsync your local YUM repository server with a CentOS 5.4 YUM mirror.
CentOS Mirror list – http://www.centos.org/modules/tinycontent/index.php?id=30
rsync="rsync -avrt --bwlimit=256"
for ver in $verlist
for arch in $archlist
for base in $baselist
$rsync $remote $local/$ver/$base/$arch/
NB! Please read creating a Local CentOS YUM repository on CentOS 5.x before implementing.

The anticipation for the release of CentOS 5.4 has been an exciting wait. So believe me when I say I was excited to read a blog post by Dag Wieers posted today “So, CentOS 5.4 has been released to mirrors”.
So time to knuckle down and start planning the update from CentOS 5.3 to CentOS 5.4, first step is adding the CentOS 5.4 yum repository to our local yum repository.

So, CentOS 5.4 has been released to mirrors and will be available soon as updates to your existing systems. This ends about 6 weeks of suspended security fixes, although some security fixes were released in the CentOS 5.3 repository before the actual 5.4 release was ready.
Most of what is new can be found from my earlier RHEL5.4 release blog post.

RT @CentOS: 5.4 is baked! CentOS internal network will start syncing up today. Release ~ soon!
CentOS 5.4 will be hitting our local CentOS mirrors and YUM repositories shortly, so in anticipation for the release lets take a look at the history and trends of CentOS 5 releases.
The Google Trend graph below shows a nice steady upwards trend on the generic CentOS search phrase which is a good indication of a growing and stable Linux distribution.
The below Google Trend graph compares the different versions of CentOS 5. What’s great to see is that there is a steady overall growth in the CentOS camp and with every new release, with the previous version tailing off, the newer CentOS version takes the lead and continues the steady upwards trend.
