I just wanted to kick in my 2 cents. I run about 50 domains for my company off a PDNS/MySQL setup on 5 geographically diverse servers (OpenVPN connecting them). We skipped the multi-master simply because (for us) the records aren't changing that much. If the master goes down, big whoop, we loose a single name server (Because the master DB is also a name server)... the other 4 slaves (slash name servers) will keep running and keep serving.
You have to screw up purdy bad to break it. The only major concerns I have are replication failing. openvpn failing (and replication failing)... but the biggest concern is user error (IE "update `records` set content='1.2.3' where 1"... whoops). -Jon On Thu, Sep 15, 2011 at 21:12, Johannes Ernst <[email protected]>wrote: > I'm thinking of setting up a multi-master MySQL backend, where the masters > are geographically distributed and run a local instance of PowerDNS each. > > The theory is that it would provide HA, and also allow more than one name > server for my domain, e.g. > ns1.example.com > ns2.example.com > and the master-master replication would make sure they stay consistent. > > I could put a PowerAdmin at http://ns1.example.com/ and > https://ns2.example.com/, and using either would be equivalent. > > I have not been able to find any usable information on this setup.
