converting a RHEL machine into CentOS

+1 vote
45 views

Google found nothing in this list archives for me but did find this :
http://www.unixmen.com/how-to-jul-convert-rhel-5-to-centos-5/

Before I just go try that on one of my systems can someone confirm that it works?

I'm running RHEL 5.7 so I guess I'd replace the 5.4 in the URL with 5.7. Basically I let my RHEL licenses run out (never really used them) and am getting warnings now from yum. Want to just switch over to the CentOS repos.

This CentOS wiki article will help you:

Here is what I did

mkdir /root/centos
cd /root/centos
wget http://vault.centos.org/5.0/os/x86_64/CentOS/centos-release-5-0.0.el5.centos.2.x86_64.rpm
wget http://vault.centos.org/5.0/os/x86_64/CentOS/centos-release-notes-5.0.0-2.x86_64.rpm
rpm -e --nodeps redhat-release-notes redhat-release yum-rhn-plugin redhat-logos
rpm -ivh *.rpm
yum -y update

And it all looks good!

It seems that RHEL 7 will only support 64 bit. Is this correct, and what for Centos 7? Also the ARM info I found was the target is ARMv8 which is 64 bit, not the ARMv7 which is 32bit.

Any clarification?

I've seen several articles that listed Centos 6.x as vulnerable, but DID NOT LIST RHEL 6.

I'd think that if Centos 6.x is vulnerable, then so would RHEL 6.x, since Centos is made from RHEL sources.

Does anyone know for sure either way?
