# Generate SSL certificate
sudo certbot certonly --standalone -d your-domain.com

# Configure Nginx reverse proxy
server {
    listen 443 ssl;
    server_name your-domain.com;
    
    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
    
    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Firewall Configuration

Secure your server with UFW:

# Enable UFW
sudo ufw enable

# Allow SSH
sudo ufw allow ssh

# Allow HTTPS only
sudo ufw allow 443/tcp

# Block direct access to OpenClaw port
sudo ufw deny 8080/tcp

Monitoring and Maintenance

Regular maintenance ensures optimal performance after you install OpenClaw on Linux server. Set up monitoring and automated maintenance routines:

Log Management

Configure log rotation and monitoring:

sudo nano /etc/logrotate.d/openclaw

/var/log/openclaw/*.log {
    daily
    missingok
    rotate 30
    compress
    notifempty
    copytruncate
}

Backup Strategy

Implement automated backups:

# Backup script
#!/bin/bash
BACKUP_DIR="/backups/openclaw/$(date +%Y%m%d)"
mkdir -p $BACKUP_DIR

# Backup database
docker-compose exec -T db pg_dump -U openclaw openclaw_db > $BACKUP_DIR/database.sql

# Backup configuration
cp -r ~/openclaw/.env $BACKUP_DIR/
cp -r ~/openclaw/config/ $BACKUP_DIR/
