  Yeah this didn't work for me. I ran these commands and I'm getting errors when i click on jobs in my puppet enterprise console 

  Error retrieving jobs: Unexpected error 500 occurred - Host name 'XXXX.XXX' does not match the certificate subject provided by the peer (CN=XXX.XXX)

   

  pemaster puppetserver: Exception in thread "main" java.lang.IllegalArgumentException: Unable to open 'ssl-cert' file: /etc/puppetlabs/puppet/ssl/certs/puppetenterprise.dsa.reldom.tamu.edu.pem

  So when do you change your host name on a CentOS7 Box? Before I do all this or at the end?

  So trying to make this work, this KB worked fine until you reboot the box then i get SSL errors.
