Cant create CNAME Record in AWS

2
votes

I have a domain (mydomain.com). I use AWS Route 53 to point this comain to a server hosted on EC2. I was able to add a CNAME record for 'www.mydomain.com' or 'someprefix.mydomain.com'. Route 53 has SOA and NS record for 'mydomain.com' and does not allow to add a CNAME record for 'mydomain.com'.

I need this record to be able to type the domain with or without the leading 'www' in the browser.

More important, I plan to run a mail server on the machine and I believe mail clients need to resolve the 'mydomain.com' part of my user email addresses (e.g. [email protected]).

How do I do that?

To make it all hang together... Set up

  • A mydomain.com # Sets up your main domain
  • CNAME www.mydomain.com # Sets up your www domain. (you may want to redirect one to the other to avoid duplicate content
  • NS ns.whatever.com
    ns2.whatever.com
  • MX mail.mydomain.com

This is assuming your not using ELB

A CNAME cannot point to the root domain. Same DNS services will allow it, but a CNAME should point to a service on the domain. ie - the www service in the above case.
