I have managed to set up multiple puppet masters with one puppet master acting as a CA and clients are able to get a certificate from this CA server but use their designated puppet master to get their manifests. See this question for more info.. multiple puppet masters. However, there are a couple of things I have had to do to get this working correctly and have an error which I'll get to.
First of all, to get inventory working for a puppet-client (PC) connecting to its designated puppet-master (PM), I had to copy the CA certs on PM1 to the PM2 ca directory. I ran this command:
scp
[email protected]:/var/lib/puppet/ssl/ca/*
[email protected]:/var/lib/puppet/ssl/ca/.
Once i have done that, I was able to uncomment the SSLCertificateChainFile, SSLCACertificateFile & SSLCARevocationFile section of my rack.conf VH file on the PM2. Once I had done this, inventory started to work. Does this sound an acceptable way to do things?
Secondly, in the puppet.conf file, I am setting the designated PM server for that client. Unless there is a better way, this is how it'll work in my production setup. So PC1 will talk to PM1 and PC2 will talk to PM2. This is where I have an error. When PC2 first requests a cert from the CA on PM1, the cert appears and then I sign the cert on the CA on PM1. When I then do a puppet agent --test on PC2 (which has server = PM2 in puppet.conf), I get this error:
Warning: Unable to fetch my node definition, but the agent run will continue:
Warning: Error 403 on SERVER: Forbidden request: puppet-master2.test.net(10.1.1.161) access to /certificate_revocation_list/ca [find] at :112
However, if I
change the PC2 puppet.conf file and specify server = PM1 and the rerun puppet agent --test, i do not get any errors. I can then revert the
change in the puppet.conf file back to server = PM2 and everything seems to run normally.
Do I have to set up some kind of ProxyPassMatch on PM2 for requests made from clients to /certificate_revocation_list/* and redirect them to PM1? Or how can I fix this error?
Cheers, Oli
