Note that the chef_server_url field in our example uses a fake DNS hostname of
default-centos65.vagrantup.com because that's the hostname vagrant set up. If you try

will discover that it is not valid.
Chef Server requires that hosts have valid fully qualified domain names set up in your local
domain name service (DNS). In production, you would have your Chef Server hostname
configured in your Domain Name System (DNS) server before installing Chef Server. Let's

base in lieu of making a DNS change, as we are just doing a book exercise.
