Puppet error : Could not create master.pid

puppetpuppet-agentpuppetmaster

I've configure puppet server and client, when I run puppet master --verbose --no-daemonize on puppet server, I get following message, 

Notice: Starting Puppet master version 3.8.4
Error: Could not run: Could not create PID file: /var/run/puppet/master.pid

what could be the possible solution ?

Best Answer

The error err: Could not retrieve catalog from remote server indicates that the puppet agent was unable to contact the puppetmaster.

Ensure the puppet agent is configured with the puppetmaster's hostname or fully qualified domain name. View /etc/puppetlabs/puppet/puppet.conf and in section [main], confirm the value of server is correct.

Example configuration:

[main]
certname = puppetmaster01.example.com
server = puppet
environment = production
runinterval = 1h
strict_variables = true
trusted

In the above example the server name puppet must be the address of the puppetmaster.

See the puppet configuration documentation.

Second, ensure the puppetmaster's hostname or fully qualified domain name resolves to an IP address. Fix your DNS if it does not resolve.

Use dig or another tool to ensure the name resolves correctly:

dig puppet

Lastly, check the firewall on the puppetmaster. Ensure all the required ports are allowed in the firewall configuration as specified in the documentation.
