Eric,
There's a couple options.
One is to change the repo files on all of your hosts, but that's annoying
and doesn't scale well.
There's a second that probably highly unsupported, but it's worked well
for me for many years. It relies on playing games with DNS.
1) You have to make your clients believe that mirrorlist.centos.org is on
a webserver you control. I did this by creating a DNS zone for
mirrorlist.centos.org and having it resolve to one of my webservers.
2) The webserver you point them to needs to reply with something that
looks like the list returned by the real mirrorlist. I created
/index.cgi (and added index.cgi to the DirectoryIndex and enabled CGI
execution for .cgi files). The contents of index.cgi are:
----- BEGIN index.cgi -----
#!/usr/bin/perl
use strict;
use warnings;
use CGI qw (param);
my $baseurl = 'http://mirror.chpc.utah.edu/pub/centos/';
print "Content-type: text/plain\n\n";
print $baseurl, param('release'), '/', param('repo'), '/', param('arch'),
'/', "\n"
----- END index.cgi -----
This makes every client that uses my DNS server use my CentOS mirror. One
advantage is that it requires no client configuration. To stop it, I
remove the DNS override from my name server. To continue, I put the
override back. One disadvantage is that each client only gets one mirror,
so if there's something wrong with my mirror, they don't have any others
to try.
As I said before, probably highly not-recommended, but it seems to have
worked OK for me.
Thanks,
DR
