Hardware and Software Requirements
Before we begin the Pi-hole tutorial, let’s ensure you have everything you need.
Hardware:
- Raspberry Pi (Recommended): A Raspberry Pi is the most popular choice for running Pi-hole due to its low power consumption and affordability. A Raspberry Pi Zero W or a Raspberry Pi 4 will work perfectly. Note that you can also use other Linux-based systems, such as a virtual machine or a dedicated server.
- MicroSD Card: An 8GB or larger microSD card to store the operating system and Pi-hole software.
- SD Card Reader/Writer: To flash the operating system onto the microSD card.
- Ethernet Cable (Recommended): A wired Ethernet connection provides a more stable and reliable network connection compared to Wi-Fi.
- Power Supply: A suitable power supply for your Raspberry Pi.
Software:
- Raspberry Pi OS (formerly Raspbian): The recommended operating system for Raspberry Pi. We’ll be using Raspberry Pi OS Lite for a minimal footprint.
- SD Card Flashing Tool: Software like BalenaEtcher or Raspberry Pi Imager to write the operating system image to the microSD card.
- SSH Client (Optional): For remote access to your Raspberry Pi via SSH (Secure Shell). PuTTY (Windows) or the built-in terminal (macOS/Linux) can be used.
Step-by-Step Pi-hole Installation Guide
Now that you have the necessary hardware and software, let’s proceed with the Pi-hole tutorial.
Step 1: Installing Raspberry Pi OS
- Download Raspberry Pi OS: Go to the official Raspberry Pi website and download the latest version of Raspberry Pi OS Lite. The Lite version is sufficient for Pi-hole as it doesn’t include a graphical desktop environment, reducing resource usage.
- Flash the OS to the microSD Card: Use BalenaEtcher or Raspberry Pi Imager to flash the downloaded Raspberry Pi OS image to your microSD card. Select the image file and your microSD card as the target device.
- Enable SSH (Optional but Recommended): Before booting the Raspberry Pi, enable SSH for remote access. On Linux and macOS, you can create an empty file named
ssh
in the boot partition of the microSD card. On Windows, you can use a text editor like Notepad++ to create the file (ensure it doesn’t have a file extension).
This step allows you to configure your Pi-hole remotely and is very convenient for future maintenance. - Configure Wi-Fi (If Using Wi-Fi): If you’re using Wi-Fi instead of Ethernet, create a file named
wpa_supplicant.conf
in the boot partition of the microSD card. Add the following lines, replacingYOUR_WIFI_SSID
andYOUR_WIFI_PASSWORD
with your actual Wi-Fi network name and password:
country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1network={
ssid="YOUR_WIFI_SSID"
psk="YOUR_WIFI_PASSWORD"
}
Change country=US according to your country code.
Step 2: Booting and Connecting to Your Raspberry Pi
- Insert the microSD Card: Insert the microSD card into your Raspberry Pi.
- Connect to Power and Network: Connect the Raspberry Pi to a power source and an Ethernet cable (or ensure it’s within range of your Wi-Fi network if you configured Wi-Fi).
- Find the Raspberry Pi’s IP Address: You’ll need to find the IP address assigned to your Raspberry Pi. You can usually find this in your router’s administration interface (look for a device named
raspberrypi
or similar). Alternatively, you can use a network scanning tool likenmap
.
The IP address will be used to connect to the Raspberry Pi via SSH. - Connect via SSH: Open your SSH client (PuTTY or your terminal) and connect to the Raspberry Pi using the IP address you found. The default username is
pi
, and the default password israspberry
. It’s crucial to change the default password after logging in for security reasons.
Step 3: Updating the System and Installing Pi-hole
- Update the System: Once connected via SSH, update the Raspberry Pi’s package list and upgrade installed packages:
sudo apt update
sudo apt upgrade -y
- Install Pi-hole: Run the Pi-hole installation script:
curl -sSL https://install.pi-hole.net | bash
This will launch an interactive installer.
- Follow the On-Screen Instructions: The installer will guide you through the Pi-hole setup process. Here are some key settings to consider:
- Static IP Address: It’s highly recommended to assign a static IP address to your Raspberry Pi. The installer will ask if you want to use the current IP address as static. Choose “Yes” unless you have a specific reason to change it. Alternatively, you can configure static DHCP on your router, which is often a better solution.
- DNS Provider: Choose a DNS provider. Google, Cloudflare, and OpenDNS are popular choices. Consider privacy-focused DNS providers for increased anonymity.
- Web Admin Interface: Enable the web admin interface for easy management of your Pi-hole.
- Logging: Enable query logging to view blocked and allowed domains.
- Web Interface Password: You will be prompted to set a password for the web interface. Choose a strong password and remember it.
Step 4: Configuring Your Router to Use Pi-hole
The final step is to configure your router to use your Pi-hole as its primary DNS server. This will ensure that all devices on your network use Pi-hole for DNS resolution, enabling ad blocking.
- Access Your Router’s Configuration Page: Open a web browser and enter your router’s IP address (usually
192.168.1.1
or192.168.0.1
) into the address bar. You’ll need your router’s username and password to log in. - Find the DNS Settings: Locate the DNS settings in your router’s configuration interface. The location of these settings varies depending on your router model. Look for settings related to “DNS Server,” “WAN Settings,” or “Internet Settings.”
- Enter the Pi-hole’s IP Address: Enter the static IP address of your Pi-hole as the primary DNS server. You can optionally enter a secondary DNS server, such as Google’s public DNS (
8.8.8.8
or8.8.4.4
), as a backup in case your Pi-hole is unavailable. - Save the Changes: Save the changes to your router’s configuration. Your router may need to restart for the changes to take effect.
Accessing the Pi-hole Web Interface
After configuring your router, you can access the Pi-hole web interface by opening a web browser and navigating to http://pi.hole/admin
or http://YOUR_PIHOLE_IP_ADDRESS/admin
, replacing YOUR_PIHOLE_IP_ADDRESS
with the actual IP address of your Raspberry Pi. Log in using the password you set during the installation process.
The web interface provides a dashboard with key statistics, such as the number of queries blocked, the percentage of ads blocked, and the top blocked domains. You can also use the web interface to manage your whitelist, blacklist, and DNS settings.
Customizing Your Pi-hole Setup
Pi-hole offers a variety of customization options to fine-tune your ad-blocking experience.
Whitelisting and Blacklisting
You can whitelist domains to prevent them from being blocked and blacklist domains to ensure they are always blocked.
- Whitelisting: If a website or service isn’t working correctly, it may be due to a blocked domain. Use the whitelist to allow the necessary domains. Access the Whitelist section of the web interface (Domains > Whitelist) and add the domain you want to allow.
- Blacklisting: If you encounter ads that are not being blocked, you can add the corresponding domains to the blacklist. Access the Blacklist section of the web interface (Domains > Blacklist) and add the domain you want to block.
Adding Additional Blocklists
Pi-hole uses a default list of ad-serving domains. You can enhance its blocking capabilities by adding additional blocklists from various sources. The community maintains lists of reliable ad and tracking domains that are updated regularly.
*Be careful when adding lists as some could cause issues with normal website use.*
- Access the Adlists Section: In the web interface, navigate to Settings > Adlists.
- Add New Adlists: Enter the URL of the adlist you want to add in the “Address” field and click “Add.”
- Update Gravity: After adding or modifying adlists, run
pihole -g
via SSH or click the “Update Gravity” button in the web interface to update the local database with the new blocklists.
Using Custom DNS Servers
While the installer gives the option to select DNS servers, these can be changed at any time.
- Access the DNS Section: In the web interface, navigate to Settings > DNS.
- Select DNS Servers: Choose your preferred DNS Servers.
- Save and restart: Click “Save” at the bottom of the page.
Troubleshooting Common Issues
Sometimes, you may encounter issues with your Pi-hole setup. Here are some common problems and their solutions.
- No Internet Access: Ensure that your Raspberry Pi has a stable network connection and that your router is configured to use your Pi-hole as the DNS server. Double-check the IP address you entered in your router’s settings.
- Websites Not Loading Correctly: Some websites may rely on ad-serving domains for functionality. Try whitelisting the affected domains to resolve the issue.
- Pi-hole Web Interface Not Accessible: Verify that your Raspberry Pi is running and that you can access it via SSH. Check the IP address and ensure that the Pi-hole web server is running (it should be by default).
