Setting up Puppet certificates
Run Puppet agent to generate a certificate for the Puppet Server to sign:
# puppet agent -t
Log into to your Puppet Server, and list the certificates that need approval:
# puppet cert list
It should output a list with your node’s hostname.
Approve the certificate, replacing hostname.example.com
with your agent's node name:
# puppet cert sign hostname.example.com
Back on the Puppet agent node, run the puppet agent again:
# puppet agent -t
Note
Remember that private network DNS is a prerequisite for a successful certificate signing.
