The Ultimate Raspberry Pi Home Server Guide

The Raspberry Pi isn't just a toy for learning Python. It's a capable, low-power server that can run your digital life.

Hardware Checklist

• Raspberry Pi 5 (8GB recommended): The new PCIe connector allows for NVMe SSDs!
• MicroSD Card: Get "Application Class A2". Even better: boot from USB SSD.
• Power Supply: Official 27W USB-C PSU. The Pi 5 is power-hungry.
• Cooling: The Active Cooler is mandatory for the Pi 5.

First Steps: Headless Setup

1. Use Raspberry Pi Imager on your PC.
2. Select "Raspberry Pi OS Lite" (No Desktop = More RAM for apps).
3. Click the "Settings" gear (Ctrl+Shift+X) to enable SSH and set WiFi credentials before flashing.
4. Boot it up and SSH in: ssh pi@raspberrypi.

Essential Apps (Dockerized)

Don't install apps directly. Use Docker. A simple docker-compose.yml is easier to backup than a corrupted OS.

1. Pi-hole (The Network Guard)

Blocks ads for every device on your WiFi.

• Benefit: Speeds up browsing by blocking ad trackers.
• Setup: Set your Router's DNS to the Pi's IP Address.

2. Home Assistant (The Brain)

Automate your lights, thermostat, and locks locally.

• Why Local?: If the internet goes down, your light switch should still work.

3. Plex / Jellyfin (The Media Center)

Stream your movies.

• Note: The Pi 5 has no hardware video encoder/decoder (unlike the Pi 4). It relies on CPU grunt. Direct Play is fine; 4K Transcoding is a struggle.

Power Consumption

A Pi 5 idles around 3-5 Watts. Compared to an old PC (60-100 Watts), the Pi pays for itself in electricity savings within a year in regions with high energy costs.

Conclusion

The Raspberry Pi is the perfect gateway drug to System Administration. It's cheap, low stakes (if you break it, just reflash the SD card), and teaches you real Linux skills.
