Puppet puppet agent --configprint server doesn t return a valid DNS name

Question

On running the command puppet agent --configprint server doesn't return a valid DNS name. How do i correct this?

Answer 1

Agents trust the master only if they contact it at one of the valid hostnames specified when the master was installed.

On the node, if the results of puppet agent --configprint server don't return one of the valid DNS names you chose during installation of the master, the node and master can't establish communication.

1. To edit the master's hostname on nodes, in /etc/puppetlabs/puppet/puppet.conf, change the server setting to a valid DNS name.
2. To reset the master's valid DNS names, run:

/etc/init.d/pe-nginx stop
puppet cert clean <MASTER_CERTNAME> 
puppet cert generate <MASTER_CERTNAME> --dns_alt_names=<COMMA-SEPARATED_LIST_OF_DNS_NAMES>
/etc/init.d/pe-nginx start
