📋 Prerequisites Checklist

• Ubuntu Server 22.04 LTS (or newer)
• Terminal access with sudo privileges
• Domain name (recommended for SSL)
• Basic Linux command knowledge
• Minimum 1GB RAM (2GB recommended)

🛠 Initial Server Setup

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

# Install essential tools
sudo apt install -y curl wget

🔥 Firewall Configuration

Enable firewall: sudo ufw enable

🌐 Web Server Comparison

🐧 Apache Setup Guide

1. Install Apache

sudo apt install apache2 -y

2. Virtual Host Configuration

File: /etc/apache2/sites-available/yourdomain.conf

<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName yourdomain.com
    DocumentRoot /var/www/yourdomain
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Enable configuration:

sudo a2ensite yourdomain.conf
sudo systemctl reload apache2

🚀 Nginx Setup Guide

1. Install Nginx

sudo apt install nginx -y

2. Server Block Configuration

File: /etc/nginx/sites-available/yourdomain

server {
    listen 80;
    server_name yourdomain.com www.yourdomain.com;
    root /var/www/yourdomain;
    
    location / {
        try_files $uri $uri/ =404;
    }
}

Enable configuration:

sudo ln -s /etc/nginx/sites-available/yourdomain /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx

🔒 SSL Setup with Let’s Encrypt

For Apache:

sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache --agree-tos -m [email protected] -d yourdomain.com

For Nginx:

sudo apt install certbot python3-certbot-nginx -y
sudo certbot --nginx --agree-tos -m [email protected] -d yourdomain.com

Auto-Renewal Test:

sudo certbot renew --dry-run

🧪 Verification Tests

1. HTTP Status Check: curl -I http://yourdomain.com
2. SSL Validation: openssl s_client -connect yourdomain.com:443
3. Server Header Check: curl -I | grep "Server"

🚨 Troubleshooting Tips

• Permission Issues: sudo chown -R www-data:www-data /var/www/yourdomain
• Port Conflicts: sudo lsof -i :80
• Config Errors: sudo journalctl -xe
• SSL Renewal: sudo certbot renew --force-renewal

2. Nginx Performance Tuning
3. Let’s Encrypt Documentation
4. Ubuntu Server Security

💡 Pro Tips

• Use systemd for service management:

sudo systemctl [start|stop|restart|status] apache2/nginx

• Enable HTTP/2 for better performance
• Set up automated backups with rsync
• Monitor traffic with goaccess or ngxtop

Final Recommendation:
For most users, Nginx offers better performance out-of-the-box, while Apache provides greater flexibility through .htaccess files. Choose based on your specific application requirements.
