Can we set easy-to-remember hostnames for EC2 instances?

Question

I'm running a couple of standard Fedora instances on EC2. I feel the public hostnames of the instances assigned by Amazon are too weird and hard to remember. I'd like to change them to something short (like red/blue/green/etc).

Is there any drawback in doing this? And how do I set it up such that it persists after reboots?

Answer 1

Edit /etc/sysconfig/network as root.

Replace

HOSTNAME=localhost.localdomain

with

HOSTNAME=hostname.DOMAIN_NAME

Then, either reboot or run /etc/init.d/network restart The server then should report its name as an FQDN.
