I wanted to install and play around with ganglia on my RedHat 4.1.2-50 Linux box. I found the a really good HOW TO:
http://acidborg.wordpress.com/2010/10/08/how-to-install-and-configure-ganglia-on-red-hat-enterprise-linux-5/
When I tried to do "yum install ganglia" I got the below message.
[root@isvx7 ganglia]# yum install ganglia

As the above failed, I went onto to install the Extra Packages for Enterprise Linux (
EPEL) rpm as follows

Some blogs say to check the data and time of the host doing a "yum install", and that it could cause the error message "up2date_client.up2dateErrors.SSLCertificateVerifyFailedError: The SSL certificate failed verification."
In my case the date and time were fine, and that was not the cause of the problem.
I found a workaround to the issue which says, to edit
/etc/sysconfig/rhn/up2date and change serverURL=http://... instead of https.
It fixed the "up2date_client.up2dateErrors.SSLCertificateVerifyFailedError: The SSL certificate failed verification." issue, and I was able to install ganglia using "yum install".
