Introduction

Welcome, brave sysadmin-in-training (or curious weekend hacker)! Today we’re going on a journey to install YunoHost, the Linux-based home server OS that turns any old PC or VPS into a digital Swiss Army knife—hosting websites, e-mail, chat, cloud storage and more. Buckle up, sharpen your geeky wit, and let’s dive into the magical land of self-hosting.

Why YunoHost?

• Simplicity: One-command app installs (yes, really).
• Privacy: You control your data―no corporate overlords.
• Community: A friendly forum and active developers.
• Flexibility: Over 100 pre-packaged apps (Nextcloud, WordPress, Mastodon… you name it).

System Requirements

Hardware

Software

• Another computer to prepare the installation media (Windows, macOS or Linux).
• USB flash drive (≥ 4 GB) or blank DVD.
• Internet connection for downloads and updates.

Step 1: Download the YunoHost ISO

1. Visit the official download page: yunohost.org.
2. Choose the latest stable ISO (e.g. YunoHost X.Y).
3. Save it to your computer. Feel free to dance a jig—this is the major milestone of the day!

Step 2: Verify the ISO (Optional but Recommended)

We like our downloads uncorrupted and free of gremlins. To verify:

• Download the .sha256sum file from the same page.
• Open a terminal (or PowerShell) and run:

  sha256sum -c yunohost-X.Y.iso.sha256sum

• If it says “OK,” congratulations—your ISO is squeaky clean.

Step 3: Create a Bootable USB Drive

On Linux (dd method)

sudo dd if=yunohost-X.Y.iso of=/dev/sdX bs=4M status=progress  sync

Replace /dev/sdX with your USB device. Double-check or you’ll wipe the wrong disk—oopsy!

On Windows or macOS (Etcher)

• Download Etcher.
• Select the ISO, select the USB drive, click “Flash!”

Step 4: Boot and Install

4.1 Boot From USB

• Insert USB into target machine.
• Power on and press the key (F2, F12, ESC, depending on your BIOS) to choose boot device.
• Select USB. You should see the YunoHost installer menu.

4.2 Choose Installation Mode

• Standard installation: Installs Debian and YunoHost automatically.
• Expert mode: For partition ninjas who prefer manual control.

4.3 Partitioning (Standard Mode)

Let the installer handle it: it will create a root partition, swap if needed, and format everything properly. In expert mode, make sure you have a Linux filesystem (ext4 recommended).

4.4 Locale, Keyboard Network

• Choose your language and keyboard layout.
• Set timezone.
• Configure network: DHCP is easiest. For static IP, enter your router’s settings.

4.5 Create Admin Account

• Username: admin (or your creative alias).
• Password: Choose wisely—no “1234” or “password”.

4.6 Hostname and Domain

Pick a hostname (e.g. pineapple) and a local domain (e.g. yourdomain.tld). You can use .nohost.me for a free dynamic DNS subdomain if you don’t have your own.

4.7 Finish Installation

The installer will copy files, install GRUB, and reboot. You’ll be prompted to remove the USB—do it, then press Enter. Look at that terminal magic!

Step 5: First Connection Configuration

Once rebooted, access your new server’s web admin:

https:///yunohost/admin

• Log in with the admin credentials you defined.
• Accept the self-signed SSL certificate warning (we promise you’re not being spied on… yet).

Step 6: Installing Apps

Time to populate your server with awesome tools. In the web admin interface:

1. Go to “Applications.”
2. Browse or search (e.g. Nextcloud, WordPress, Rocket.Chat).
3. Click “Install” and fill in the domain/subdomain settings.
4. Wait a few minutes while YunoHost does its magic.

Voilà! Your new app is live, ready to serve users and memes alike.

Step 7: Updates Maintenance

• Regular updates: In the web admin, check “Upgrade System” weekly.
• Backups: Configure automated backups to a remote FTP or local disk.
• Monitoring: Install netdata or Prometheus for real-time stats.

Advanced Tips Tricks

• Command Line: Use yunohost CLI for scripted installs:

  yunohost app install nextcloud --domain mycloud.nohost.me

• Fail2Ban: Brute-force protection is enabled by default. Customize rules in /etc/fail2ban/jail.local.
• Custom SSL: Replace self-signed certificates with Let’s Encrypt:
  yunohost domain cert-install yourdomain.tld --force.
• Docker on YunoHost: While not officially recommended, you can install Docker in a custom setup—watch out for port clashes!

Troubleshooting

• Can’t reach web admin? Check your firewall: ufw status or iptables -L.
• App install failed? Inspect logs: /var/log/yunohost/yunohost.log.
• DNS woes? Ensure your domain’s A/AAAA records point to your server’s public IP.
• Disk space low? Clean logs: journalctl --vacuum-size=100M or expand your partition.

Conclusion

Congratulations, you’ve just installed YunoHost and unleashed the Kraken of self-hosted services! With a sprinkle of humor and a dash of sysadmin savoir-faire, your server is now ready to host everything from personal clouds to community forums. Go forth, secure your data, and may your uptime be legendary!
