apache2_pihole.md

Prerequisites

• Ubuntu 18.04+
• Apache 2.4.18 or higher setup as described here https://gist.github.com/GAS85/8dadbcb3c9a7ecbcb6705530c1252831
• OpenSSL 1.0.2g-1ubuntu4.10 or higher

Install Pihole

Install pihole from the official repo as described here: https://github.com/pi-hole/pi-hole#one-step-automated-install, e.g. via

curl -sSL https://install.pi-hole.net | bash

During the installation please choose to install Web Interface, but to not install a Web Server.

Setup Apache2

Create Apache2 config for Pihole

Basically if you already have working apache2 config, just create file e.g. 004-pihole.conf in a /etc/apache2/sites-available/ with following content:

LAN Restriced

<IfModule alias_module>
    Alias /admin /var/www/html/admin
    <Directory "/var/www/html/admin">
        AllowOverride None
        Options None
        Order deny,allow
        Allow from 192.168.0.0/24 localhost 127.0.0.1
        #Allow from all
        Deny from all
    </Directory>
</IfModule>

In this case you can only access Pihole from the local network (192.168.0.0/24). If you would like to access from the internet also, please apply following config:

Internet access

<IfModule alias_module>
    Alias /admin /var/www/html/admin
    <Directory "/var/www/html/admin">
        AllowOverride None
        Options None
        Order deny,allow
        #Allow from 192.168.0.0/24 localhost 127.0.0.1
        Allow from all
        #Deny from all
    </Directory>
</IfModule>

Enable config

To enable Apache2 config for pihole please run:

a2ensite 004-pihole.conf

Then test our config and reload apache2 if succeed:

sudo apachectl configtest && sudo service apache2 reload

Finish

Now you can access your pihole via http(s)://YourIP_or_Domain/admin

Changing pihole URL path from /admin to /custom

If you would like to change you path from http(s)://YourIP_or_Domain/admin to e.g. http(s)://YourIP_or_Domain/custom, simply adjust Alias in 004-pihole.conf to expected path:

#Alias /admin /var/www/html/admin
Alias /custom /var/www/html/admin

And added simple rewrite rule (you have to enable apache mod_rewrite via sudo a2enmod rewrite) to your virtual host e.g. default-ssl.conf.

 #Pihole rewrite link from /admin to /pihole.
 RewriteEngine  on
 RewriteRule    "^/admin/(.*)"  "/custom/$2" [R]

Then test our config and reload apache2 if succeed:

sudo apachectl configtest && sudo service apache2 reload

Finish

Now you can access your pihole via http(s)://YourIP_or_Domain/custom

Its depends from what you would like to achieve, do you need control Raspberry PI via Alexa, or you want that Raspberry connected to it bidirectional, or you would like to make Alexa from Raspberry?

Personally I use home assistant to control my heaters, lights and curtains updated with Shelly Relays and also controlled centrally.

Note that libapache2-mod-php is need, for php to work on apache2. pihole admin page uses php.
