Raspberry Pi OS (formerly Raspbian) is the officially supported operating system and a great starting point for your home server setup. It’s based on Debian Linux and offers excellent hardware support and a wide range of available software.

Steps for Installing Raspberry Pi OS:

Download Raspberry Pi Imager: Download the official Raspberry Pi Imager from the Raspberry Pi website: raspberrypi.com/software. This tool simplifies the OS installation process.
Insert MicroSD Card: Insert your MicroSD card into your computer’s SD card reader.
Launch Raspberry Pi Imager: Open the Raspberry Pi Imager application.
Choose OS: Click on “Choose OS” and select “Raspberry Pi OS (64-bit)” for best performance (or the 32-bit version if you prefer).
Choose Storage: Click on “Choose Storage” and select your MicroSD card. Be absolutely sure you select the correct drive, as this process will erase all data on the selected drive.
Write: Click on “Write” to begin the OS installation process. The Imager will download the OS and write it to the MicroSD card.
Verify: Once the writing process is complete, the Imager will verify the installation.
Eject MicroSD Card: Safely eject the MicroSD card from your computer.

First Boot and Initial Configuration

With the OS installed on your MicroSD card, it’s time to boot up your Raspberry Pi and configure it for your home server setup.

Steps for Initial Configuration:

Insert MicroSD Card: Insert the MicroSD card into the Raspberry Pi’s MicroSD card slot.
Connect Peripherals: Connect the Ethernet cable, keyboard, mouse, and monitor (if needed for initial setup) to the Raspberry Pi.
Connect Power: Connect the power supply to the Raspberry Pi. It should boot automatically.
Raspberry Pi Configuration Tool: After booting, the Raspberry Pi Configuration tool will appear (if you’re using a desktop environment). You can also access it from the command line using sudo raspi-config.
Set Hostname: Change the default hostname to something more descriptive, like “myhomeserver”. This makes it easier to identify your server on the network.
Enable SSH: Enable SSH to allow remote access to your server from other devices on your network. This is essential for headless operation (without a monitor).
Change Password: Change the default password for the pi user to a strong and unique password. This is a critical security measure.
Configure Network: If you’re using a static IP address, configure it in the network settings. Otherwise, the Raspberry Pi will obtain an IP address automatically from your router via DHCP.
Update and Upgrade: Open a terminal window and run the following commands to update and upgrade the software packages:
sudo apt update
sudo apt upgrade

Setting up a Static IP Address (Recommended)

While DHCP is convenient, assigning a static IP address to your home server setup ensures that its IP address remains constant. This is crucial for reliable access and port forwarding.

Steps for Setting a Static IP Address:

Identify your Router’s IP Address and Subnet Mask: You can usually find this information by logging into your router’s administration panel (often accessed through a web browser by typing the router’s IP address).
Find an Available IP Address: Choose an IP address within your router’s subnet that is not currently in use. A good practice is to select an IP address outside the DHCP range configured on your router.
Edit the dhcpcd.conf File: Open the dhcpcd.conf file with root privileges:
sudo nano /etc/dhcpcd.conf
Add Static IP Configuration: Add the following lines to the end of the file, replacing the placeholders with your actual network information:
interface eth0
static ip_address=192.168.1.150/24 (Replace with your desired static IP address and subnet mask)
static routers=192.168.1.1 (Replace with your router’s IP address)
static domain_name_servers=8.8.8.8 8.8.4.4 (Google’s public DNS servers)
Save and Exit: Save the file (Ctrl+O) and exit the editor (Ctrl+X).
Reboot: Reboot your Raspberry Pi for the changes to take effect:
sudo reboot

Securing Your Home Server

Security is paramount for any home server setup. Here are some essential security measures:

Use Strong Passwords: As mentioned earlier, change the default password for the pi user and any other user accounts you create. Use strong, unique passwords that are difficult to guess.
Keep Software Updated: Regularly update your operating system and software packages to patch security vulnerabilities. Use the sudo apt update and sudo apt upgrade commands.
Enable a Firewall: A firewall controls network traffic and blocks unauthorized access. ufw (Uncomplicated Firewall) is a user-friendly option:
sudo apt install ufw
sudo ufw enable
Allow only necessary ports. For example, to allow SSH (port 22): sudo ufw allow 22
Disable Password Authentication for SSH (Optional but Recommended): Use SSH keys for authentication instead of passwords. This significantly enhances security.
Use Fail2ban (Optional but Recommended): Fail2ban automatically bans IP addresses that make too many failed login attempts. Install it with sudo apt install fail2ban and configure it according to your needs.
Regular Backups: Back up your data regularly to an external hard drive or cloud storage service. This protects you from data loss due to hardware failure or other unforeseen events.
