Notes for myself and anyone else who runs into this problem…

I was checking yum for updates on one of my Plesk servers and did yum update caching-nameserver … Bad move. It blew away the Plesk named.conf file and killed named on the box.

Here’s what you need to do to get it back:

1. First remove the rpms: yum remove caching-nameserver

2. Next, re-install the default file: cp /var/named/run-root/etc/named.conf.default /var/named/run-root/etc/named.conf

3. Now create a little shell script (found the info here and here), call it dns_rebuild.sh and run that script.
4. Lastly restart named with service named restart and you should be good to go.

Sounds easy now but that took 2 hours… Hopefully this note will save someone an hour!
