Hi, Jason.

cd /etc/yum.repos.d

I'd make a backup of the original CentOS-Base.repo:

cp CentOS-Base.repo CentOS.Base.repo.org

Open CentOS-Base.repo in a text editor, vim, emacs, whatever.

Comment out all the mirrorlist's.

# mirrorlist=http://mirrorlist.centos.org/blah-blah-blah

Make sure all the baseurl's reflects your internal repo and are not commented out.

baseurl=http//your_internal_repo/centos/$releasever/os/$basearch/

This will be my second try after trying to find a less invasive method like proxying.

Right now when a machine pulls up mirrorlist.centos.org it will point to an internal system, whose cgi behaves as such (expecting a scale issue here, vlan based load...).

You should be ok to use yum then, so long as your paths are all good. This is how I do it, anyways. Other comments or procedures are more than welcome.

Hmmm, needed to proxy the mirror.centos.org too, since up2date does not use the yum.cond.d stuff .

So to proxy

Capture all mirrorlist.centos.org and mirror.centos.org and redirect to your internal versions respectively.

Our local dns is "poisoned" to point to our internal servers. From there its all cake.

[root@host67 mirrors]# cat /var/www/html/index.cgi #!/usr/bin/perl use strict; use CGI;

my $cgi = new CGI;

my $release = $cgi->param('release'); my $arch = $cgi->param('arch'); my $repo = $cgi->param('repo');

print "Content-type: text/html\n\n"; print "http://192.168.1.67/centos/$release/$repo/$arch/%5Cn";

exit (0); [root@host67 mirrors]#

This is a bit late, I know, but I found a similar setup described at:

http://www.gurulabs.com/goodies/YUM_automatic_local_mirror.php

Their server appears to be down right now, but that's where I found the information. The original was designed for Fedora, but it was adapted to CentOS pretty easily. I've been using this for about 4 months now with great results.

Rather than spoofing the mirrorlist.centos.org entry in DNS, I just have anybody that wants to use the local mirror put an entry in their /etc/hosts file pointing to the IP address of the local server. The

Right now I am using the hosts file too.

In our server farm we are expected to make as few deviations from baseline as possible, that is why the dns redirection.

Perl CGI script adds the entry for our local server to the results returned from the real mirror list and depends on yum-fastestmirror to pick the local server from the list.

We might want to act as a gatekeeper on the mirror too, again for CM sake.

Since we don't mirror all architectures on our local server, I added some intelligence to the Perl script so that it would only add the local server if the requested repository, release, and architecture were on the local server. If anybody wants to see the final results, just let me know and I'll post my modified script and the Apache config fragment or a pointer to it.

The list might like it anyway.

We already have our up2date / yum repo.

What we need is to (minimalistically) modify the clients to use it.

Given:
