Initial Server Setup

1. Basic System Configuration

# Update system
sudo apt update && sudo apt upgrade -y

# Set timezone
sudo timedatectl set-timezone America/New_York

# Configure hostname
sudo hostnamectl set-hostname homeserver

# Create a non-root user
sudo adduser serveradmin
sudo usermod -aG sudo serveradmin

2. SSH Configuration

# Install OpenSSH server
sudo apt install openssh-server

# Configure SSH
sudo nano /etc/ssh/sshd_config

Important SSH Settings:

Port 2222                    # Change default port
PermitRootLogin no           # Disable root login
PasswordAuthentication no    # Use key-based auth
MaxAuthTries 3              # Limit login attempts

3. Set Up SSH Keys

# On your client machine
ssh-keygen -t ed25519 -C "[email protected]"

# Copy public key to server
ssh-copy-id -p 2222 serveradmin@your-server-ip

4. Firewall Configuration

# Install and configure UFW
sudo apt install ufw

# Default policies
sudo ufw default deny incoming
sudo ufw default allow outgoing

# Allow SSH
sudo ufw allow 2222/tcp

# Allow HTTP/HTTPS
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp

# Enable firewall
sudo ufw enable

Essential Software and Services

1. Docker Installation

# Install Docker (use our previous Docker guide)
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
sudo usermod -aG docker $USER

2. Portainer (Docker Management)

# Create Portainer volume
docker volume create portainer_data

# Run Portainer
docker run -d -p 8000:8000 -p 9443:9443 \
  --name portainer --restart=always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v portainer_data:/data \
  portainer/portainer-ce:latest

3. Nginx Proxy Manager

# Create docker-compose.yml
mkdir ~/nginx-proxy-manager
cd ~/nginx-proxy-manager

cat > docker-compose.yml << 'EOF'
version: '3.8'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt
EOF

# Start the service
docker compose up -d

Networking Setup

Static IP Configuration

Edit /etc/netplan/00-installer-config.yaml:

network:
  version: 2
  ethernets:
    enp1s0:
      dhcp4: false
      addresses: [192.168.1.100/24]
      gateway4: 192.168.1.1
      nameservers:
        addresses: [1.1.1.1, 8.8.8.8]

Apply changes:

sudo netplan apply

Router Configuration

Port Forwarding:

• Forward external port 80 → server port 80 (HTTP)
• Forward external port 443 → server port 443 (HTTPS)
• Forward external port 2222 → server port 2222 (SSH)

DDNS Setup:

• Configure dynamic DNS service (No-IP, DuckDNS)
• Point your domain to your home IP

Storage Configuration

Setting Up RAID (Software)

# Install mdadm
sudo apt install mdadm

# Create RAID 1 array
sudo mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sdb /dev/sdc

# Format and mount
sudo mkfs.ext4 /dev/md0
sudo mkdir /mnt/storage
sudo mount /dev/md0 /mnt/storage

# Add to fstab
echo '/dev/md0 /mnt/storage ext4 defaults,nofail,discard 0 0' | sudo tee -a /etc/fstab

ZFS Setup (Alternative)

# Install ZFS
sudo apt install zfsutils-linux

# Create ZFS pool
sudo zpool create storage mirror /dev/sdb /dev/sdc

# Create datasets
sudo zfs create storage/media
sudo zfs create storage/backups
sudo zfs create storage/documents

Monitoring and Maintenance

System Monitoring with Prometheus + Grafana

# Create monitoring stack
mkdir ~/monitoring
cd ~/monitoring

cat > docker-compose.yml << 'EOF'
version: '3.8'
services:
  prometheus:
    image: prom/prometheus
    ports:
      - "9090:9090"
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'

  grafana:
    image: grafana/grafana
    ports:
      - "3000:3000"
    environment:
      - GF_SECURITY_ADMIN_PASSWORD=admin
    volumes:
      - grafana-storage:/var/lib/grafana

  node-exporter:
    image: prom/node-exporter
    ports:
      - "9100:9100"

volumes:
  grafana-storage:
EOF

Automated Backups

# Create backup script
cat > ~/backup.sh << 'EOF'
#!/bin/bash
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/mnt/storage/backups"

# Backup important directories
tar -czf $BACKUP_DIR/home_$DATE.tar.gz /home
tar -czf $BACKUP_DIR/etc_$DATE.tar.gz /etc

# Keep only last 7 backups
find $BACKUP_DIR -name "*.tar.gz" -mtime +7 -delete

echo "Backup completed: $DATE"
EOF

chmod +x ~/backup.sh

# Add to crontab
echo "0 2 * * * /home/serveradmin/backup.sh" | crontab -

Security Best Practices

1. Regular Updates

# Create update script
cat > ~/update.sh << 'EOF'
#!/bin/bash
apt update
apt upgrade -y
apt autoremove -y
docker system prune -f
EOF

# Schedule weekly updates
echo "0 3 * * 0 /home/serveradmin/update.sh" | crontab -

2. Fail2Ban

# Install Fail2Ban
sudo apt install fail2ban

# Configure
sudo cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
sudo nano /etc/fail2ban/jail.local

3. Intrusion Detection

# Install AIDE
sudo apt install aide
sudo aideinit
sudo mv /var/lib/aide/aide.db.new /var/lib/aide/aide.db

# Schedule daily checks
echo "0 4 * * * /usr/bin/aide --check" | sudo crontab -

Next Steps

Once your home server is running:

1. Set up automated backups to cloud storage
2. Implement monitoring with alerts
3. Document your setup for future reference
4. Join communities like r/homelab and r/selfhosted
5. Experiment with new services safely using Docker

Building a home server is a journey of continuous learning. Start simple, document everything, and gradually add complexity as you become more comfortable with the system.

Remember: The best home server is the one you'll actually maintain and use!
