Help with proper FQDN naming
We have purchased an SSL certificate and need to provide the CSR. From reading earlier postings, I believe I have the correct command for doing that. However, I am confused as to what to use for the Common Name. It says “server FQDN or YOUR name”. I don’t know what they mean by YOUR name (if someone cares to explain, i’ll be happy to read it), so I’ll focus on the FQDN.
I am running Ubuntu 14.04. For this question, I will use mydomain.com as our domain name.
When I run hostname, I get “mydomain” as the response. the /etc/hostname file looks like:
127.0.0.1 localhost mydomain mydomain.com www.mydomain.com
When I enter ‘hostname -f’, I get 'localhost’. Should I set my FQDN to mydomain.com or mydomain.mydomain.com (or something else)?
