DNS and offline servers
Posted on 2007-10-20
I'm not sure I'm looking at things the best way, but here's what I intend to do on a small scale. I have two web servers and a DNS server. They are all about 10 feet away from me and I have complete admin access to them.
I'm planning to take down WebServer A for a few hours, but keep WebServer B online. While I'm doing maintenance on WebServer A, I'd like all requests for it to be answered by WebServer B.
Do I just update DNS records to point to WebServer B and then have them point back to WebServer A when I'm done, or is there a more efficient (perhaps better) way than what I'm thinking of?
The web servers are running Debian 4 and the DNS is running Mac OS X Server.
Thanks in advance!
