6-11-2015, DNS continued (status: done)

• Setup DNS servers on all 3 servers at home, each primary masters, since they won't change, its okay to just copy them all and make them independent and not make them secondary DNS servers.
• Setup AWS DNS server for local domain. 
• apt-get install bind9
• Setup resolv.conf : Not sure which did, but restarting the server made resolv.conf right. 
• Added "nameserver 127.0.0.1" to the file /etc/resolvconf/resolv.conf.d/head.
• /etc/resolvconf/resolv.conf.d/head:search mylocaldomain us-east-2.compute.internal
• /etc/resolvconf/resolv.conf.d/base:search    mylocaldomain us-east-2.compute.internal
• Added the forwarder to the amazon DNS. 
• To the file /etc/bind/named.conf.options
• forwarders {     172.32.0.2;           };
• Add add this but you should add more restrictions. Since l let AWS restrict by network  put this in. Otherwise, none of your servers will be able to query it. 
• allow-query { any; };
• Follow the steps in the previous doc from "Now setup the DNS for your own network."
• Being an idiot, I didn't figure out the command to restart the netowork, so just reboot it. 
• Get the ip addresses from the EC2 console, or the scripts. 
• Finally, to let the other servers use your DNS server:
• Open up the DNS port only to those servers you trust. 
• Add your DNS server /etc/resolvconf/resolv.conf.d/head  on those servers. 
• TODO --- this needs to be done, last step. 
• At home, each is a master. DONE
• AWS

For AWS servers......

echo "nameserver 1.1.1.1" >> /etc/resolvconf/resolv.conf.d/head

echo "search mylocaldomain us-west-2.compute.internal" >> /etc/resolvconf/resolv.conf.d/head
echo "search mylocaldomain us-west-2.compute.internal" >> /etc/resolvconf/resolv.conf.d/base
reboot # I must find a better way.
After reboot, test DNS entries.

DONE at home and work.
I will need to maintain this, but I am going to leave it out of SALT. Now to SALT, then voltdb, vertica,  DAD.
