puppet

My puppet master server had a hardware failure, and I have restored to another box. However this box has different hardware and hostname.

If I restore the existing /etc/puppet directory to the new server, the puppetmaster will not start with the following error;

# puppetmasterd --debug --verbose Could not prepare for execution: Retrieved certificate does not match private key; please remove certificate from server and regenerate it with the current key

So what steps do I need to take to allow the new puppetmaster to start, and to generate a new puppetmaster certificate using the old ca..

Also will the puppet clients actually report in to a different puppet server using a server certificate that has been generated with the old CA?

as seen on Server Fault - Search for 'Server Fault'
After running logrotate, Puppet starts writing it's logs into /var/log/puppet/masterhttp.log-20130616. How come it doesn't keep logging in /var/log/puppet/masterhttp.log? It seems normal behavior is renaming the original log-file and start with a clean fresh log-file to start writing in that log… >>> More
