At the weekend I got into a discussion with Andy Stanford-Clark and Richard Appleby on Twitter troubleshooting basic application installation in Red Hat Enterprise Linux (like Pidgin). Not finding a solution later began to plague me, I grabbed a copy of RHEL and installed it on a Virtual Machine to solve the problem. If you’re interested in the history of the Red Hat-based distributions, please see my other article.
Are you registered to the Red Hat Network (RHN)?
If not, you will see messages like this when trying to use the “yum” package installer.
[root@localhost ~]# yum install pidgin
Loaded plugins: rhnplugin, security
This system is not registered with RHN.
RHN support will be disabled.
Setting up Install Process
No package pidgin available.
Nothing to do
[root@localhost ~]#
Don’t panic, you might be able to use CentOS packages
First you need to add the CentOS repository, create this file using your favorite text editor:
[root@localhost ~]# vi /etc/yum.repos.d/centos.repo
Adding the following contents, note the ‘5’ has to be hardcoded to either 5 or 6 depending on your RHEL version.
[centos]
name=CentOS $releasever - $basearch
baseurl=http://ftp.heanet.ie/pub/centos/5/os/$basearch/
enabled=1
gpgcheck=0
Once you’ve completed this step, you can now use “yum” to install CentOS packages.
Installing a package from CentOS
Here we’re installing the popular IM client Pidgin from the CentOS repository:
[root@localhost ~]# yum install pidgin
Loaded plugins: rhnplugin, security
Repository centos is listed more than once in the configuration
This system is not registered with RHN.
RHN support will be disabled.

Misson Accomplished!
You now have a working version of Pidgin with its dependencies courtesy of CentOS.

Mike, thanks for this info. I changed my ‘centos.repo’ file to access the CentOS main mirror site instead. Change the release version number “6.3” as per your system.
[centos]
name=CentOS $releasever – $basearch
baseurl=http://mirror.centos.org/centos/6.3/os/$basearch/
enabled=0
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/6.3/os/$basearch/RPM-GPG-KEY-CentOS-6
then install pidgin –
# yum –enablerepo=centos install pidgin
Thanks so much! I was able able to install TigerVNC server using this method on RHEL 6.6 x86_64. Just changed the 6.3 to 6.6.
Once you’ve completed this step, you can now use “yum” to install CentOS packages.
thakns Mr.Michael Cutler. u have done a great help to me
I am still getting error
[root@supportlinux /]# yum install pidgin

you have down me a great help, thanks
thanks – works like a charm!
Thanks Michael.. it helped me a lot..:)
Saved my hide!! and sanity!!
That , really saved my day
Thx
Awesome Mike. I just took a redhat training and they gave us iso files to play with, but no subscriptions so this is very very helpful.
You are amazing! thanks you very much
Michael, THANK YOU VERY MUCH!!!!!!!!!!
Thanks! Works perfectly!
whether it should be the same version with centos? I am using RHEL 6.3.
I’ve used this a few times and thought I’d give a thanks for the info! Quick and easy, thanks!
THANK YOU SOOOOOOOOOOOOOOOOOOOOOOOO MUCH. KISS YOU !!!
Thanks
Thank you, took me an hour to finally find a solution.

Mike, Thank you soooo much.. i was spending hours to get around the problem !!
Thanks for info.Saved my life 🙂

One hell of a helpful article, thanks
Very Usefull article thanks
It made things simple for me to install tomcat on RHEL6 from centos repository. Thanks a lot for this article
You are a life-saver. I inherited an old RHEL system with a long-expired subscription, and this helped fix things for sure. After configuring centos.repo, if you are still having trouble, try running “yum clean all” to reset the cache.
Thank you very much ,
I have been for days trying to make my repository on red hat works .
Now it does thank you 😀
Thankyou,, Thats really help me.. Thankyou very much

Thanks a lot for this post!
I am new to Linux. I struggled for hours to yum install git without subscription to RHN.
Keep doing the deed!
This did not work for me – the url failed. What I found that does work is all of the above using:
baseurl=http://vault.centos.org/5.11/os/$basearch/
This is pointed to by the centos repos.
Thanks man.
