DNS server installation and configuration (Part 3) - Pi-Hole installation (EN)

In the previous part it was explained how to add two-factor authentication (2FA) for SSH access.

Pi-Hole Installation

In this phase, Pi-Hole, an open-source software, will be installed. It acts as a DNS sinkhole and optionally as a DHCP server. This application filters DNS requests to drastically reduce advertising present in web pages.

Download official repository

As the first step, download the Pi-Hole repository: git clone --depth 1 https://github.com/pi-hole/pi-hole.git Pi-hole.

Pi-Hole 2

At the end of the download, enter the folder: cd 'Pi-hole/automated install/'.

Pi-Hole 4

Prepare Pi-Hole installation

From this directory, launch the bash script: sudo bash basic-install.sh. It may ask for the user password as it is launched with administrator privileges. If so, enter it and press Enter.

Pi-Hole 6

Wait for a moment for compatibility checks and conflicts.

Pi-Hole 7

Press Enter for each of the two screens to start the configuration.

Configure Pi-Hole installation

Since the router has been set as a static IP, we can confirm by selecting Continue and pressing Enter.

Pi-Hole 10

Select the same interface to which the IP used throughout the entire procedure was assigned. In this case, the first one. Press Enter to confirm.

Pi-Hole 11

Select a temporary DNS provider. Later it will be removed as the computer with Ubuntu Server will become its own DNS resolver at port 5353 and address 127.0.0.1.

Pi-Hole 12

Select Yes to include third-party lists to filter content and confirm by pressing Enter.

Pi-Hole 13

Confirm the installation of the web interface for making further changes to the settings. Select Yes and press Enter.

Pi-Hole 14

Confirm the installation of the lightweight web server lighttpd to make the web interface functional. Select Yes and press Enter.

Pi-Hole 15

Enable logging of queries for potential debugging of problems. Select Yes and press Enter.

Pi-Hole 16

In this screen, you can choose how many contents are visible from the admin web interface. Leave the default Show everything. Select Continue and press Enter.

Pi-Hole 17

Here, the auto-generated password for logging into the web interface via the computer's IP will be displayed. It's not important to remember it since it will be changed with a longer one for security reasons later. Press Enter to continue.

Pi-Hole 18

Once the Pi-Hole configuration procedure is completed, you can proceed to change the admin interface password (not to be confused with the user password).

Pi-Hole 19

To change the Pi-Hole web interface password, use the command pihole -a -p.

Pi-Hole 20

After pressing Enter, enter the password, press Enter again, re-enter the password, and finally confirm with the Enter key.

Pi-Hole 21

If the procedure was successful, the text New password set will appear.
