If you’re looking for a low-power, always-on solution for streaming your personal media library, the Raspberry Pi makes a great Plex server. It’s compact, quiet, affordable, and perfect for handling basic media streaming—especially for home use.

In this post, I’ll guide you through setting up Plex Media Server on a Raspberry Pi, using Raspberry Pi OS (Lite or Full) or Debian-based distros like Ubuntu Server.

What You’ll Need

• Raspberry Pi 4 or 5 (at least 2GB RAM, 4GB+ recommended)
• microSD card (32GB+), or SSD via USB 3.0
• External storage for media (USB HDD/SSD or NAS)
• Ethernet or Wi-Fi connection
• Raspberry Pi OS (Lite or Desktop)
• A Plex account (free is enough)

Step 1: Prepare the Raspberry Pi

1. Flash Raspberry Pi OS using Raspberry Pi Imager
2. Enable SSH and set hostname (optional)
3. Boot the Pi, log in, and update:

sudo apt update && sudo apt upgrade -y

Step 2: Install Plex Media Server

Plex is available for ARM-based devices via their official repository.

1. Add Plex repo and key:

curl https://downloads.plex.tv/plex-keys/PlexSign.key | sudo apt-key add -
echo deb https://downloads.plex.tv/repo/deb public main | sudo tee /etc/apt/sources.list.d/plexmediaserver.list
sudo apt update

2. Install Plex:

sudo apt install plexmediaserver -y

Step 3: Enable and Start the Service

Enable Plex on boot and start the service:

sudo systemctl enable plexmediaserver
sudo systemctl start plexmediaserver

Make sure it’s running:

sudo systemctl status plexmediaserver

Step 4: Access Plex Web Interface

Open your browser and go to:

http://<your-pi-ip>:32400/web

Log in with your Plex account and begin the setup wizard.

Step 5: Add Your Media Library

Plug in your external HDD or mount a network share, then:

sudo mkdir -p /mnt/media
sudo mount /dev/sda1 /mnt/media

Make sure Plex can access it:

sudo chown -R plex:plex /mnt/media

Add the media folder during the Plex setup under Library > Add Library.

Optional Tips

• Transcoding: The Pi can handle direct play (no transcoding) well, but struggles with transcoding large files. Use compatible formats like H.264 (MP4).
• USB Boot: For better performance, boot the Pi from an SSD instead of a microSD card.
• Power Supply: Use a proper 5V/3A PSU to avoid crashes under heavy disk load.
• Thermal: Add a heatsink or fan for the Pi if using Plex for long sessions.

Secure Your Server

• Use your router to forward port 32400 only if you want remote access.
• Set a strong Plex password.
• Enable Tailscale or WireGuard for secure remote access without exposing ports.

Conclusion

A Raspberry Pi might not replace a full-blown NAS or dedicated server, but for personal use or as a secondary Plex node, it’s surprisingly capable. With low energy usage and silent operation, it’s the perfect DIY home media solution.

If you’re running other services like Pi-hole or Home Assistant, the Pi can multitask well — just avoid overloading it with too much transcoding.

Asahi Linux is a groundbreaking project that aims to bring native Linux support to Apple Silicon devices, including the new M1 and M2 MacBooks. This initiative has garnered significant attention from the open-source community and tech enthusiasts alike, as it opens up new possibilities for using these powerful devices with a fully functional Linux operating system. In this blog post, we’ll delve into what Asahi Linux is, its significance, and how you can install it on your newer MacBook.

What is Asahi Linux?

Asahi Linux is an open-source project dedicated to porting Linux to run natively on Apple Silicon processors. The project was initiated by Hector Martin, a well-known figure in the Linux and hacking communities, with the goal of making Linux fully operational on Apple’s new ARM-based architecture. The name “Asahi” comes from the Japanese word for “rising sun,” symbolizing a new dawn for Linux on Apple hardware.

Why Asahi Linux Matters

Apple’s transition from Intel to its custom ARM-based processors (M1, M1 Pro, M1 Max, and M2) has been a game-changer in the tech industry. These chips deliver impressive performance and efficiency, but they also present challenges for running alternative operating systems due to their proprietary nature. Asahi Linux is important because:

1. Openness and Flexibility: It provides an open-source alternative to macOS, allowing users to harness the full potential of their Apple Silicon devices with the flexibility and customization that Linux offers.
2. Development and Research: Developers and researchers benefit from having access to a Linux environment on Apple Silicon, enabling them to work on projects that require Linux-specific tools and software.
3. Community and Collaboration: The project fosters collaboration within the open-source community, bringing together developers and enthusiasts to contribute to and improve the Linux experience on Apple hardware.

Current Status of Asahi Linux

As of now, Asahi Linux has made significant progress, with many core components working on Apple Silicon devices. These include:

• Basic device support, such as USB, PCIe, and NVMe.
• Display output and keyboard/mouse input.
• Networking and storage functionalities.
• Early support for graphics acceleration.

However, it is important to note that Asahi Linux is still under active development, and some features, such as advanced power management and full GPU support, are still being refined.

How to Install Asahi Linux on Newer MacBooks

If you’re excited to try out Asahi Linux on your Apple Silicon MacBook, here’s a step-by-step guide to get you started.
