title: How do I install the optional channel for RHEL to install Puppet?
body: <p>I'm trying to install Puppet on RedHat Linux Version 7.</p>
  
  <p>The instructions say you need to install an "optional channel".  </p>
  
  <p>Can someone provide directions on how to do this?  I want to install Puppet. I tried to install Puppet Master without the optional channel.  The main thing that is wrong is that I cannot start puppetmaster.</p>
  
  <p>When I try and run:</p>
  
  <pre><code>/etc/init.d/puppetmaster restart
  </code></pre>
  
  <p>But I get this:</p>
  
  <pre><code>-bash: /etc/init.d/puppetmaster: No such file or directory
  </code></pre>
