Hi!
At the moment geoip backend does not support SQL database, there is
geosql backend in the works, but I don't know how that is coming along.
If you are willing to give it a try you could configure your system
to create the YAML configuration file for GeoIP backend using some cron
job or similar. GeoIP backend is able to reload it's configuration without
restarting auth by giving PoweDNS Auth reload command using
pdns_control reload
As general though, I would delegate one name to the GeoIP backend,
like, geo.yourdomain.com
This way you can, if you want, delegate service names back to MySQL
by defining www.geo.yourdomain.com IN CNAME www-%cn.yourdomain.com. Just be
sure to have an IP for all continents, and it will return
www.geo.yourdomain.com IN CNAME www-eu.yourdomain.com
style of replies, which, if you have the domains in same auth, should
be resolved to an IP eventually.
Another alternative, if you want to take advantage of geoip's features,
is to do it in two steps. In this, you will get
www.geo.yourdomain.com IN CNAME server.yourdomain.com
which will again end up in IP address.
Sample config for first alternative:
domains:
- domain: geo.yourdomain.com
ttl: 60
records:
geo.yourdomain.com:
- soa: ns1.geo.yourdomain.com hostmaster.yourdomain.com yada yada...
- ns: ns1.geo.yourdomain.com
- ns: ns2.geo.yourdomain.com
services:
www.geo.yourdomain.com: 'www-%cn.yourdomain.com'
And for second alternative:
domains:
- domain: geo.yourdomain.com
ttl: 60
records:
geo.yourdomain.com:
- soa: ns1.geo.yourdomain.com hostmaster.yourdomain.com yada yada...
- ns: ns1.geo.yourdomain.com
- ns: ns2.geo.yourdomain.com
www-eu.geo.yourdomain.com:
- cname: server.yourdomain.com
www-us.geo.yourdomain.com:
- cname: server-us.yourdomain.com
www-any.geo.yourdomain.com:
- cname: server-3.yourdomain.com
services:
www.geo.yourdomain.com: ['www-%cn.geo.yourdomain.com',
'www-any.geo.yourdomain.com']
You can read more about geoip backend at
https://doc.powerdns.com/md/authoritative/backend-geoip/
The GeoSQL backend is https://github.com/PowerDNS/pdns/pull/2375
but it appears to be still incomplete.
