Basics Flashcards
if it hasn’t already been created, you can create a simple puppet.conf file using the following command:
puppetmasterd –genconfig > puppet.conf
Puppet’s configuration will be located under the ? directory. Puppet’s principal configuration file is called puppet.conf and is stored:
/etc/puppet directory /etc/puppet/puppet.conf.
In the puppet.conf what are the 3 sections
[agent] section configures the Puppet agent,[master] section configures the Puppet master binary. There is also a global configuration section called [main]. All components of Puppet will set options specified in the [main] section.
In puppet.conf specifies the name of the Puppet master. How would you add the certname value to the [master] section
[master] certname=puppet.example.com
What file tells Puppet where and what configuration to load for our clients?.
