PowerDNS

On Debian, install the relevant packages. At time of writing, this is version 4.1.6

apt-get install pdns-server pdns-backend-sqlite3
apt-get install sqlite3
apt-get remove pdns-backend-bind

Remove the bind backend config (as of 4.1.6 it doesn't support slave configs managed through pdnsutil) and create one for SQLite3.

rm /etc/powerdns/pdns.d/bind.conf
cat >> /etc/powerdns/pdns.d/sqlite3.conf <<EOF
launch += gsqlite3
gsqlite3-database=/var/lib/powerdns/powerdns.sqlite3
EOF

Update the main config to enable slave mode:

(UNTESTED) perl -spi -le 's/^# slave=yes/slave=yes/' /etc/powerdns/pdns.conf

Make sure there's a line uncommented saying "slave=yes"

Create the SQLite3 database and fix permissions

sqlite3 /var/lib/powerdns/powerdns.sqlite3 < /usr/share/pdns-backend-sqlite3/schema/schema.sqlite3.sql
chown pdns: /var/lib/powerdns /var/lib/powerdns/powerdns.sqlite3

Restart the service

systemctl restart pdns

Set it to start automatically

systemctl enable pdns

Assuming it comes up ok, you can add slave zones with the following command:

pdnsutil create-slave-zone bocks.com 78.129.196.11
