You can set your droplet's FQDN by running the following commands:

nano /etc/sysconfig/network

Edit it so that it looks like this:

HOSTNAME="ns1.mydomain.com"

Edit /etc/hosts and add a line that looks like this:

127.0.0.1 ns1.mydomain.com ns1

If there's a line with both "localhost" and "ns1", delete "ns1" from that line.

Finally, reboot your droplet.
