How to Set Up WordPress on the Raspberry Pi?

In this comprehensive guide, you’ll learn step-by-step how to install WordPress on a Raspberry Pi. We’ll cover everything from setting up the operating system to optimizing WordPress for best performance. Follow along to build your own Pi-powered WordPress site.

What You’ll Need

Before we begin, let’s look at what you’ll need to complete this project:


  • Raspberry Pi board (any model will work)
  • MicroSD card (16GB Class 10 recommended)
  • Power supply for Raspberry Pi
  • Ethernet cable or WiFi dongle


  • Raspberry Pi Imager
  • A WordPress package (we’ll use the Bitnami installer)

Step 1: Install the Raspberry Pi OS

The first step is to install the Raspberry Pi OS operating system on your MicroSD card. This will allow us to then install software onto the Raspberry Pi.

  1. Download the latest Raspberry Pi OS (32-bit) from the official website.
  2. Connect your SD card to your computer either directly or with a USB adapter.
  3. Open Raspberry Pi Imager and select the Raspberry Pi OS you downloaded.
  4. Choose your SD card as the destination and click “Write”. This will install the OS.

Once finished, insert the MicroSD card into the Raspberry Pi. Connect your Pi to a display, keyboard, mouse, Ethernet cable/WiFi, and power supply. Boot it up to arrive at the Raspbian desktop.

Your base OS is now setup and we can move on to installing WordPress.

Step 2: Configure Raspberry Pi Settings

Before installing software, it’s best to configure some system settings on the Raspberry Pi. This helps ensure we have the right environment for running WordPress.

Here are some recommended settings changes:

  1. Open the Raspberry Pi Configuration menu from Preferences > Raspberry Pi Configuration
  2. On the System tab: set hostname and password
  3. On the Interfaces tab: enable SSH if you want to access remotely
  4. Finish with OK and reboot when prompted

Configuring these basic settings sets us up nicely for installing WordPress next.

Step 3: Install WordPress Using Bitnami

There are a couple methods for installing WordPress on the Raspberry Pi. We’ll use the Bitnami installer as it handles all the dependencies and server configuration for us.

Here are the steps to install WordPress with Bitnami:

  1. SSH into your Pi if not already connected
  2. Download the latest Bitnami WordPress module with wget
  3. Make the installer executable sudo chmod +x Bitnami-wordpress-
  4. Run the installer sudo ./Bitnami-wordpress-* and accept the license agreement
  5. Select all default options when prompted by the installer
  6. Once finished, WordPress can be accessed at http://{your Pi’s IP address}/

The Bitnami installer automated many complex steps for us. We now have WordPress installed and ready to finish configuration.

Step 4: Complete WordPress Setup Wizard

With WordPress now installed on our Pi, we need to wrap up the initial configuration via the web UI.

  1. In your web browser, navigate to your Pi’s IP address followed by /wp-admin/install. Php e.g.
  2. Choose your language then click “Continue”
  3. Accept the license terms by clicking “Let’s go!”
  4. On the next screen:
    • Enter database name, username and password (use defaults from Bitnami if unsure)
    • Enter site title, username, password, and email
    • Check the privacy checkbox
  5. Click “Install WordPress” button to finish

You will now arrive at the WordPress login. Enter the admin username and password you just configured. Once logged in, you have a fully functioning WordPress site powered by your Pi!

Step 5: Secure WordPress

Fresh WordPress installations can often be vulnerable to attacks. Here are some tips to quickly secure and optimize your site:

Set Strong Passwords

Update the WordPress and admin passwords to be complex and at least 12 characters long. You can edit the password under Users > Profile in the dashboard.

Limit Login Attempts

Use a plugin like Cerber Security to set a limit on invalid login attempts. This prevents brute force attacks.

Disable File Editing

Disable the file editor in WordPress unless needed. Remove this vector for injecting malicious code by blocking access under Settings > General.

Configure Trusted Hosts

Add your own URLs as the only trusted hosts under Settings > General to prevent spoofing attacks.

Enable Two-Factor Authentication

Adding 2FA provides an extra layer of account security for your WordPress login. Use a plugin like 2Factor or pick a provider listed in the repository.

Securing your new site upfront helps avoid future threats and hacking attempts.

Step 6: Optimize WordPress Performance

In addition to security, a best practice is to optimize WordPress to perform well on the Raspberry Pi. Here are some areas to tune for better speed and loading times.

Cache Plugin

A caching plugin stores rendered webpages to serve faster on repeat visits. This avoids resource intensive processing each time. Some plugins like WP Rocket offer configuration for limited environments like the Pi.

Image Compression

Compressed images load quicker for your visitors. Plugins like Opti mole can intelligently shrink images without sacrificing quality. This makes a noticeable difference on constrained devices.

Content Distribution Network

Using a CDN to serve static files increases performance by hosting on servers closer to visitors. Once secured, you can enable CDN access in the wp-config file.

Database Optimization

Tweaking the MySQL database improves queries for generating pages. Adjust cache and concurrent connection limits based on RPi hardware specs for better results.

There are many other areas like Gzip compression and minification of assets that can optimize WordPress on the Pi. As long as security is maintained, aim for maximum speed.

Key Takeaways

  • The Raspberry Pi provides an affordable way to self-host and experiment with WordPress
  • Using a tailored installer like Bitnami streamlines the normally complex installation steps
  • Always secure fresh WordPress sites by addressing common vulnerabilities right away
  • Optimizing for the Pi’s limited resources results in better performance vs other hardware
  • Configuring the web stack properly prevents future issues as your site grows

With what you learned here, you can comfortably get WordPress running on a Pi. Feel free to build out more functionality or modify as you see fit.


Getting WordPress successfully installed on Raspberry Pi can be a challenging but fun project for gaining useful skills. Carefully working through setup, security precautions, performance tuning, and troubleshooting creates a tailored environment for running WordPress on constrained hardware.

The lightweight nature and customizability of WordPress allows it to run even on the modest Pi boards. While performance limits remain, the hands-on experience you gain through self-hosting is invaluable despite small hiccups you encounter.

As you continue using your Pi WordPress site, remember to keep backups, plan for future growth capacity, and secure it according to latest best practices as you would any production website.


  1. My WordPress site feels slow despite optimizations. How can I speed it up further?
    Try a static site generator like Jekyll to convert WP content into simple static pages. This reduces database and processing overhead.

  2. What’s the best Raspberry Pi model for hosting WordPress?
    Pi 4 Model B with 4GB RAM offers the best performance. Pi 3 B+ can also work with lightweight config. Avoid Pi Zero and earlier models.

  3. Can I use WordPress plugins like normal if running on the Pi?
