Puppet users - Jun 2009 - Running multiple puppet masters behind nginx

Hi puppet list,

I''m currently modifying my puppet setup to get it redundant.

I actually have a puppet master, running mongrel behind nginx. It''s on
a
single machine, with no backup (backup for the service, not the files).

The machine is called puppet.mydomain.com

I want to move it to 2 machines, running mongrel, behind 2 nginx in
failover with heartbeat.

Mongrel --|
Mongrel --|-- Nginx--|
Mongrel --|          |
     |               |
  NFS stuff          |--Heartbeat IP
     |               |
Mongrel --|          |
Mongrel --|-- Nginx--|
Mongrel --|

(hoping that your mail client does not break this magnificient piece of
ASCII art)

To achieve this I''ve setup a new machine, called "silicium"
and then
mounted /var/lib/puppet via NFS. This dir is a copy of
the /var/lib/puppet from the original "puppet" machine. It has all the
SSL stuff to handle puppet.mydomain.com.

The problem is that I want "silicium.mydomain.com" to be able to
handle
requests destinated to "puppet.mydomain.com". The SSL stuff is handled
by nginx so it should not be a problem, but it looks like it is. I think
it runs under its own FQDN, ignoring the "puppet.mydomain.com" pem
files. I tried adding certname=puppet.mydomain.com in the [puppetmaster]
section of puppet.conf but nothing changed.

Any clue ?

Thanks

Nico.
