thanks to Craft Computing for putting together a easy to follow tutorial for setting up Pi-hole with Unbound DNS for extra privacy

Important

don't forget to set boot option to wait for network (i.e. raspi-config)

Update script with Logging

#! /bin/bash

DATE=`date +%Y-%m-%d`
LOG="./update.log"
echo $DATE > $LOG

echo "[ pihole -up ]" >> $LOG
pihole -up         >> $LOG
echo "=============" >> $LOG

echo "[ apt update ]" >> $LOG
apt-get update      >> $LOG
echo "============" >> $LOG

echo "[ apt upgrade ]" >> $LOG
apt-get upgrade -y  >> $LOG
echo "============" >> $LOG

backup

also a backup of PiVPN

#! /bin/bash

DATE=`date +%Y-%m-%d`

echo '======================' > backup.log
echo $DATE >> backup.log


if pihole -a -t\
&& mv /home/pi4/scripts/backup/pi-hole-rpi-teleporter* /home/pi4/scripts/backup/pihole\
; then
        echo 'pihole SUCCESS' >> backup.log
else
        echo 'pihole failed' >> backup.log
fi


if pivpn -bk\
&& sudo mv /home/pi4/pivpnbackup/* /home/pi4/scripts/backup/pivpn\
; then
        echo 'pivpn SUCCESS' >> backup.log
else
        echo 'pivpn failed' >> backup.log
fi

Resolve DNS for the Raspberry PI

Try to ssh into Raspberry Pi (or whatever you host Pi-Hole on) and try to ping any local DNS entries (that you would have set up in PiVPN). These are not reachable because the Pi itself is not resolving to the local domain name service because it is higher up the stream. We can manually tell the pi to resolve itself (assuming Pi-hole and PiVPN are running on the same machine).

sudo nano /etc/dhcpcd.conf

find the line and add 127.0.0.1 and save.

static domain_name_servers=127.0.0.1

sudo service dhcpcd restart
