Convert RHEL 6 to CentOS 6.3

Every so often I search the Internet and I find what I am looking for to solve a problem.  This site has all of the steps to do what I wanted to do.  I have a server at my house that has been turned off for a few months.  It had an expired RHEL 6 license and I did not want to continue to pay for the subscription since the client that I built it for was no longer my customer.  I did want to continue to use the server so I wanted to convert it to CentOS.  I found some simple steps and then I tweaked them for the current release.

So these are the steps to upgrade from RHEL 6 to CentOS 6.3

  1. # yum clean all

  2. # mkdir ~/centos

  3. # cd ~/centos

  4. # wget http://mirror.centos.org/centos-6/6.3/os/x86_64/RPM-GPG-KEY-CentOS-6

  5. # wget http://mirror.centos.org/centos-6/6.3/os/x86_64/Packages/centos-release-6-3.el6.centos.9.x86_64.rpm

  6. # wget http://mirror.centos.org/centos-6/6.3/os/x86_64/Packages/yum-3.2.29-30.el6.centos.noarch.rpm

  7. # wget http://mirror.centos.org/centos-6/6.3/os/x86_64/Packages/yum-3.2.29-30.el6.centos.noarch.rpm

  8. # wget http://mirror.centos.org/centos-6/6.3/os/x86_64/Packages/yum-utils-1.1.30-14.el6.noarch.rpm

  9. # wget http://mirror.centos.org/centos-6/6.3/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

  10. # rpm --import RPM-GPG-KEY-CentOS-6

  11. # rpm -e --nodeps redhat-release-server

  12. # rpm -e yum-rhn-plugin rhn-check rhnsd rhn-setup rhn-setup-gnome

  13. # yum upgrade


As I write this my system is downloading all updates and doing the updating. I'll know everything is OK after a reboot.

I also wanted to visit a few of my favorite spots before I left.

Georgia on my mind

Texas was not deep enough in the south for me so I relocated to Albany, Georgia. I have been her almost a month and the adventure of living in a new city and working at a new institution are still fresh. This week week as I walked across the campus with my paper notebook in hand I was whistling as I passed through groups of students go to classes. I noticed how everyone of them was either talking on a mobile device or listening to music on them. I marveled at how odd I must seem to them as I walked without having any electronic device turned on and instead i was making the music with my lips. Albany Georgia is a lot like Portland, only smaller and really flat. Albany has the Flint River running through the middle of the downtown area and lots of pine and pecan trees all over.
