Pihole VM

2 minute read

Description:

So the other day my Pihole3 started making a very high pitch squeeking sound and I had to power it off. I’ve had if for a few years or so but wanted to see if I can move Pihole to a VM instead since my gaming computer is on all the time anyways. Here is what I did to move it over:

To Resolve:

  1. First, in HyperV I copied my template Rocky8 VM and spun it up. It comes with a default name and IP so I changed those and rebooted.

  2. Next, I added firewall rules:

    1
2
3
4
5

    firewall-cmd --permanent --add-service=http --add-service=dns
firewall-cmd --permanent --new-zone=ftl
firewall-cmd --permanent --zone=ftl --add-interface=lo
firewall-cmd --permanent --zone=ftl --add-port=4711/tcp
firewall-cmd --reload

  3. Download and install:

    mkdir pihole
cd /home/gerry/pihole
wget -O basic-install.sh https://install.pi-hole.net
sudo install wget -y
sudo chmod +x ./basic-install.sh
sudo bash basic-install.sh

SELinux Enforcing detected, exiting installer

sudo setenforce 0
sudo getenforce
# Says permissive but default is still enforcing

sudo vi /etc/selinux/config, set to permissive

run installer...

fails: Unsupported OS detected: Rocky 8.7
      If you are seeing this message and you do have a supported OS, please contact support.

run again: sudo PIHOLE_SKIP_OS_CHECK=true bash basic-install.sh

  4. Change UI password pihole -a -p

  5. Restore backup from old pihole

  6. Fix IP address where it has two IPs
