In the last post we set up the recursor server to forward requests for our domain to the authoritative server. In this post I will set up replication so that adding a record on the primary will be replicated to the secondary.

Primary Setup

On the Raspberry Pi that is acting as the primary, we will enable primary operation, and configure the IP addresses to allow transfer and notification with.

Configuration

/etc/powerdns/pdns.d/transfer.conf

primary=yes

allow-axfr-ips=192.168.0.12
also-notify=192.168.0.12:5300

The IP address needs to be the IP address of the secondary server. Remember to add the port 5300 to the notify setting.

Restart

Restart the Authoritative Server with the command:

sudo systemctl restart pdns

Update Zone

Finally we need to tell PDNS that this is a Primary zone with the following command:

sudo pdnsutil set-kind hlab.domain primary

Secondary Setup

On the Raspberry Pi that is acting as the secondary, we will enable secondary operation, configure the IP to allow transfers and notifications from, and set the frequency to check.

Configuration

/etc/powerdns/pdns/transfer.conf

secondary=yes

allow-axfr-ips=192.168.0.11
allow-notify-from=192.168.0.11
slave-cycle-interval=60

Restart

Restart the Authoritative Server with the command:

sudo systemctl restart pdns

Update Zone

Finally we need to tell PDNS that this is a Secondary zone, and what server is the Primary with the following commands:

sudo pdnsutil set-kind hlab.domain secondary
sudo pdnsutil change-secondary-zone-primary hlab.domain 192.168.0.11

Done

Replication should now be working!
