Are you tired of intrusive ads and unwanted tracking on your network? Installing Pi-hole on Red Hat Enterprise Linux (RHEL) can help you regain control over your browsing experience. In this article, we will guide you through the installation process, using insights and questions sourced from Stack Overflow, while also providing additional explanations and practical examples to enhance your understanding.

What is Pi-hole?

Pi-hole is a network-wide ad blocker that functions as a DNS sinkhole. By intercepting DNS queries and blocking requests to known ad servers, Pi-hole eliminates advertisements before they reach your devices, ensuring a cleaner and faster browsing experience.

Prerequisites for Installing Pi-hole on RHEL

Before proceeding with the installation, ensure that you have the following prerequisites:

A system running RHEL 7 or later.
Root access to the system or the ability to use sudo for administrative commands.
Basic knowledge of terminal commands and network configuration.

Installation Steps

Step 1: Update Your System

First, update your RHEL system to ensure that you have the latest packages and security updates. Open a terminal and run:

sudo dnf update -y

Step 2: Install Required Packages

Pi-hole requires some additional packages to function correctly. Install them with the following command:

sudo dnf install -y git curl

Step 3: Download and Run the Pi-hole Installer

You can install Pi-hole by downloading the installer directly from the official GitHub repository. Use the command below to fetch and run the installer:

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

This command initiates the Pi-hole installation script. During the installation, you’ll be prompted to select various configuration options.

Step 4: Configure Your Network Settings

During the installation, you will be asked to choose an upstream DNS provider. Options may include Google, OpenDNS, Cloudflare, or you can specify a custom one. Make sure to select a reliable provider for optimal performance.

Step 5: Set Up Static IP Address

Pi-hole works best with a static IP address. When prompted, select the option to configure a static IP for your Pi-hole instance. If you are uncertain about your network configuration, you can check it using:

ip addr show

Step 6: Complete the Installation

Follow the prompts to complete the installation. Once finished, Pi-hole will display a summary of your settings, including the admin web interface URL. Make sure to save this information for future access.

Common Issues and Troubleshooting

Question: Why can’t I access the Pi-hole admin interface?

A user on Stack Overflow highlighted issues with accessing the Pi-hole admin dashboard. If you face this challenge, consider the following troubleshooting steps:

Ensure that the firewall allows traffic to the Pi-hole port (default is 80).
Check if your web browser is using the Pi-hole DNS to resolve addresses. If not, configure your devices to use the Pi-hole as their DNS server.
Use the command pihole -a -t to toggle the web interface.

Question: How do I whitelist a domain in Pi-hole?

To whitelist a domain in Pi-hole, you can either use the web interface or the terminal. If you're using the terminal, the command looks like this:

pihole -w example.com

Final Thoughts and Additional Value

Installing Pi-hole on RHEL provides a robust solution to enhance your browsing experience by blocking unwanted ads and trackers. Beyond simple installation, consider regularly updating your Pi-hole to keep your blocklists current and your network secure.

Pro Tip: Customizing Block Lists

For advanced users, customizing your block lists can significantly improve Pi-hole’s performance. You can add lists like Energized Protection or StevenBlack's hosts for even more comprehensive ad blocking.
