Installing Pi-hole on Existing Apache Server

FAQs Community How-to's

I'm adding this here in case anyone else needs it. But mostly so I can "Google" it the next time I install Pi-hole on Apache.

Installing Pi-hole on an existing and working Apache web server on Raspberry Pi. This assumes you have set up your own static IP and whatnot.

  1. Run the Pi-hole install. When you get to "Do you wish to install the web server" select "Off".
  2. Finish the Pi-hole installation process. Do not panic.
  3. Run "sudo usermod -a -G pihole www-data"
  4. Install "sudo apt install php-sqlite3"
  5. At a minimum, restart Apache "sudo service apache2 restart" or reboot the Pi.
  6. Enjoy.

Thank you, this was helpful! Just wanted to add two things in case it helps someone else.

  • If you have Apache but not PHP yet, run sudo apt install php libapache2-mod-php.
  • On a fresh install of Pi-hole v5.3.1 the group membership was already setup (edit: but that's probably because I installed lighttpd).

I am working from a NextCloud install first then installing PiHole afterwards. I had trouble allowing the correct access via different port than 80. I chose 81.

  1. Added it to new pihole.conf in the /etc/apache2/sites-available

sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/pihole.conf

sudo nano /etc/apache2/sites-available/pihole.conf
added or edited the following lines:
<VirtualHost *:81>
DocumentRoot /var/www/html/admin/
<Directory /var/www/html/admin/>

  1. Added a new Listen port in the port.conf

sudo nano /var/apache2/ports.conf
add line:
Listen 81

  1. Whitelisted the directories for pihole specifically in the apache2.conf

sudo nano /var/apache2/ports.conf
add lines at the appropriate spot:
<Directory /var/www/html/pihole/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted

	<Directory /var/www/html/admin/>
        Options Indexes FollowSymLinks
        AllowOverride None
	    Require all granted
	</Directory>
  1. Finally update the Apache2 config files & restart service

sudo a2ensite pihole
sudo systemctl reload apache2

Not sure if that was all overkill or I opened it up too much but that I how I got it working on my R-Pi 4.
Documenting it to help out anyone else who was a NOOB like me…

I have managed to get the dashboard working by installing the following packages with apache+php8.0

php8.0-sqlite3
php8.0-fpm

You will also need to do
a2enconf php8.0-fpm

This last bit did the trick for me. Thank you.

I am running bullseye on a Raspberry Pi 3.
