DNS Server - failover
I have managed to setup successful replication/migration of my web server hosted files, IIS metabase and MySQL to a second server on a regular basis.
My goal now is to have name servers on the primary and "failover" server. I want the DNS updated to the failover ip if the primary server fails a test (ping or http etc), and then revert back when the primary server is ok again.
The tricky part is that I want the primary NS to be on the main server, so how do I update the DNS record if the primary server is down (you cant update secondary servers as far as i know).
Idealy I would also like the 2nd DNS server to automatically pick up new zones entered on the primary zone. that way I wont have to setup the DNS on the 2nd serverfor every new domain, although this isnt so critical.
Anyone got any advice ?
Thanks
