Step 1: Download Ubuntu Server

1. Visit Ubuntu Server downloads
2. Download Ubuntu Server 22.04.3 LTS (or latest LTS)
3. Download Rufus or balenaEtcher to create bootable USB

Step 2: Create Bootable USB

Using Rufus (Windows):

1. Insert USB drive (8GB+)
2. Open Rufus
3. Select your USB device
4. Click “SELECT” and choose the Ubuntu ISO file
5. Leave other settings as default
6. Click “START”

Using balenaEtcher (Cross-platform):

1. Install and open balenaEtcher
2. Click “Flash from file” and select Ubuntu ISO
3. Select your USB drive
4. Click “Flash!”

Step 3: Install Ubuntu Server

1. Boot from USB: Insert USB into target machine, boot from USB (usually F12 or F2 during startup)

2. Installation wizard:

   • Choose language: English
   • Select “Install Ubuntu Server”
   • Choose keyboard layout
   • Configure network (use DHCP for now)

3. Storage configuration:

   • Use entire disk (for beginners)
   • Confirm disk selection
   • Warning: This will erase all data on the drive

4. Profile setup:

   • Your name: Your Name
   • Server name: homeserver (or whatever you prefer)
   • Username: Choose something memorable (not ‘admin’ or ‘root’)
   • Password: Use a strong password

5. SSH Setup:

   • ✅ Enable “Install OpenSSH server” (critical for remote access)
   • Skip importing SSH keys for now

6. Featured Server Snaps: Skip for now

7. Install and reboot

Step 4: First Boot & Initial Setup

1. Login with the username/password you created

2. Update the system:

sudo apt update && sudo apt upgrade -y

3. Find your server’s IP address:

ip addr show

Look for something like 192.168.1.100 under your network interface.

Step 5: Configure SSH (Remote Access)

1. Test SSH from another computer:

ssh yourusername@192.168.1.100

2. Set up SSH key authentication (more secure):

On your main computer:

ssh-keygen -t ed25519 -C "your-email@example.com"
ssh-copy-id yourusername@192.168.1.100

3. Disable password authentication (optional but recommended):

sudo nano /etc/ssh/sshd_config

Find and change:

PasswordAuthentication no

Restart SSH:

sudo systemctl restart ssh

Step 6: Basic Security Setup

1. Configure UFW firewall:

sudo ufw enable
sudo ufw allow ssh
sudo ufw allow 22/tcp
sudo ufw status

2. Set up automatic security updates:

sudo apt install unattended-upgrades
sudo dpkg-reconfigure unattended-upgrades

Select “Yes” to enable automatic security updates.

Step 7: Essential Package Installation

# System monitoring and utilities
sudo apt install htop neofetch tree curl wget git -y

# Media server capabilities
sudo apt install ffmpeg -y

# File sharing (SMB/CIFS)
sudo apt install samba -y

# Web server (if you want to host websites)
sudo apt install nginx -y

Step 8: Set Static IP (Optional but Recommended)

1. Edit netplan config:

sudo nano /etc/netplan/00-installer-config.yaml

2. Replace contents (adjust IPs for your network):

network:
  version: 2
  ethernets:
    enp0s3:  # Your interface name (check with 'ip addr show')
      dhcp4: no
      addresses:
        - 192.168.1.100/24
      gateway4: 192.168.1.1
      nameservers:
        addresses:
          - 8.8.8.8
          - 8.8.4.4

3. Apply changes:

sudo netplan apply

Step 9: Basic File Sharing Setup

Create a shared folder:

mkdir /home/shared
sudo chown nobody:nogroup /home/shared
sudo chmod 777 /home/shared

Configure Samba:

sudo nano /etc/samba/smb.conf

Add at the bottom:

[shared]
   path = /home/shared
   browseable = yes
   read only = no
   guest ok = yes

Restart Samba:

sudo systemctl restart smbd
sudo ufw allow samba

Now you can access \\192.168.1.100\shared from Windows or smb://192.168.1.100/shared from Mac/Linux.

Step 10: Monitoring & Maintenance

Check system status:

# System info
neofetch

# Running processes
htop

# Disk space
df -h

# System logs
sudo journalctl -f

Set up automatic backups (basic script):

nano ~/backup.sh

Add:

#!/bin/bash
# Basic backup script
rsync -av /home/shared/ /backup/shared/
echo "Backup completed: $(date)" >> /var/log/backup.log

Make executable:

chmod +x ~/backup.sh

What’s Next?

Your Ubuntu home server is now ready! From here you can:

• Install Docker for containerized applications
• Set up Plex/Jellyfin for media streaming
• Configure VPN server for secure remote access
• Install Nextcloud for your own cloud storage
• Set up game servers (Minecraft, etc.)
• Create automated backup systems

Troubleshooting

Can’t connect via SSH?

• Check firewall: sudo ufw status
• Verify SSH is running: sudo systemctl status ssh
• Check IP address: ip addr show

Lost connection after netplan changes?

• Connect via physical access
• Check config: sudo netplan --debug apply
• Revert: Edit /etc/netplan/00-installer-config.yaml back to DHCP

Performance issues?

• Check resources: htop
• Check disk space: df -h
• Check logs: sudo journalctl -f
