Configure PowerDNS, Poweradmin, and a MySQL backend
PowerDNS is a useful tool with a web interface (Poweradmin) that can make your DNS management easier. This document is to assist with the conversion process from bind’s named.conf file format.
First, tar and copy to the new server your named.conf and all included zone files from /var/lib/named, /etc/bind, or wherever your distro saves your zone files. In this example, the conf and zone files were copied into local folder ‘namedfiles.’ Modify the path specified in the named.conf to point to this local folder.
Next, create your zones manually in Poweradmin. Let’s assume the MySQL database name is powerdns. Go into mysql and identify the domain_id/id for each:
Next, prepare zone2sql options for conversion. You will want to specify the start-id number.
Examine your import.sql file and make any necessary changes, such as replacing the new SOA name servers.
Finally, import the sql:
You should now see the domains and records populated in Poweradmin.
Download the RPM’s if available; SuSE/SLES has them available on th SuSE Build Service for 32 or 64 bit platforms.
pdns-x.x.x.rpm, pdns-mysql-backend-x.x.x.rpm, pdns-recursor-x.x.x.rpm
Edit your /etc/pdns/pdns.conf file with these parameters:
recursor, range of allowed addresses (more to come here later)
Set powerdns to start at boot with: chkconfig on pdns
Test with: nslookup servername @dnsserver and it should come back with a quick reply.
Install PowerAdmin, the apache tool to allow easy management of DNS IP addresses. Requires PHP.
Set up MySQL replication so your primary server updates the secondary DNS server. See the “Perfect Setup” how-to document available on the web.
