We’re just starting to get our feet wet with Puppet and we found the documentation woefully underwhelming. Here are our notes for getting a basic master/agent setup going with a “Hello world” manifest.

Basic Assumptions: SELinux is disabled

On your master

• Install puppet and puppetserver packages

      yum install puppet puppetserver

• Create the Puppet Master CA by running

      sudo puppet master --verbose --no-daemonize

  Once Notice: Starting Puppet master version appears, CTRL+C

• Configure the following in the main/master section of /etc/puppet/puppet.conf

      dns_alt_names = host.fqdn.tld,alt_name
      environment_timeout = unlimited
      environmentpath = $confdir/environments
  

• Create the following directories
  • /etc/puppet/environments/production
  • /etc/puppet/environments/production/manifests
  • /etc/puppet/environments/production/modules
• Create /etc/puppet/environments/production/manifests/site.pp with the following

  notify {"Hello world!":}

• Run service puppetserver start
• Open 8140 on firewall rules

On your agent

• Install puppet
• Configure /etc/puppet/puppet.conf with the following

      server = hostname.fqdn.tld
      environment = production
  

• Run puppet agent --test or start the puppet agent via service puppet start

On Master

• Run puppet cert sign agenthostname.fqdn.tld

On agent

• Run puppet agent --test and look for Hello world notice
