Changing a Puppet Master

Question

I have installed Puppet Master on Linux and configured a puppet client/agent node. I want to change my puppet master and make the puppet client as the new puppet master. How can I do it?

Answer 1

Sometimes it may be necessary to change the Puppet Master.

To point a particular client to a new Puppet Master, follow the steps given below.

On the Puppet Client:

• Enter the following changes into the /etc/puppet/puppet.conf file.

• Code Changes on Client to Switch Puppet Masters

server = new.puppet.master.fqdn
ca_server = new.puppet.master.fqdn
ca_port = 8141

• To remove all files and sub-directories in the /var/lib/puppet/ssl directory, run the following:

 cd /var/lib/puppet/ssl. 
 rm -rf ./*.

• Assuming the new Puppet Master has been set up to properly accept the client, type puppet agent --test to run a full Puppet run while pointing to the new server.

• The client will now be synchronized with the new Puppet Master.

On the Old Puppet Master:

• Remove or comment out all items for the client node in the /etc/puppet/hieradata/hosts space.

• To run puppet agent in noop mode to ensure that there are no inadvertent errors, run the following:

puppet agent --test --noop
