CentOS 5.6 Patch Version Control


Hello all,

I have this project at work. We are a MS Windows shop, and I am "supposed" to be the linux expert, which means, linux support, it's me.

I have worked with linux maintaining PCs at home with different versions of linux since 1995, jumping from Slackware to Ubuntu.

Now, I have two CentOS 5.6 boxes, and I need to control the patching process. the boxes are hosting an application which we don't manage. So. one box in production, one box in development. The idea is that the box in development wil use yum in a standard way and download whatever patches are needed, and the application is tested. When the testing is done (this can take minutes, hours, or days) then the production box gets patched.
The problem is that I need to garantee that exactly the same patches are applied in development and in production.
My idea is that the development box downloads the patches from the internet, but the production box gets it's patches from the development box, not the internet.
I have played around with making local repos on the development box and samba, or rsync the /var/yum/cache, and to change the yum.repo.d CentOS-base.repo to force the prod to go to the dev box, without success.
I would appreciate the community suggestions.
Thanks,
Edgar.

I think your best approach is to set up a local repo, then do:

1) rsync from a CentOS mirror site. Instructions are in the CentOS wiki
2) Update your dev machine using yum to the local repo
3) test it out until you are happy
4) Update your production machine the same way

that should not be a problem
i bet you will find that the updates will not cause problems on the "development" box
CentOS/RHEL dose NOT upgrade major versions in a series
The major versions of all CentOS 5 will not change over the life
now minor versions will BUT not for 5.6
only if you were to upgrade to 5.7 ( and you will have to at some point )

so 5.6 bug fixes & security fixes will not cause you problems ( safe 99.9% of the time)
BUT
in about a year the REQUIRED upgrade to 5.7 ? might?
cent ONLY supports the CURRENT version .Right now that is
4.9
5.6
6.0
there are NO backported fixes to older versions
for that BUY rhel5.6 and a support license
