Step-by-Step Installation Guide

Step 1: Install Ubuntu Server

First, download Ubuntu Server 22.04 LTS from the official website and create a bootable USB drive. Install Ubuntu Server on your dedicated hardware with these considerations:

During installation:

• Choose “Install Ubuntu Server”

• Configure network settings with a static IP address

• Create a strong username and password

• Enable OpenSSH server for remote management

• Select “Install security updates automatically”

Step 2: Initial Server Configuration

After installation, log into your server and perform these essential updates:

sudo apt update && sudo apt upgrade -y
sudo reboot

Configure timezone and locale settings:

sudo timedatectl set-timezone America/New_York
sudo locale-gen en_US.UTF-8

Step 3: Install Apache Web Server

Apache is the most popular web server software and perfect for beginners. Install it with:

sudo apt install apache2 -y
sudo systemctl start apache2
sudo systemctl enable apache2

Verify the installation by checking the service status:

sudo systemctl status apache2

Step 4: Configure Firewall Security

Security is crucial for any web server. Configure UFW (Uncomplicated Firewall) to protect your server:

sudo ufw enable
sudo ufw allow ssh
sudo ufw allow 'Apache Full'
sudo ufw status

This configuration allows SSH access and HTTP/HTTPS traffic while blocking all other incoming connections.

Step 5: Install MySQL Database Server

Most websites require database functionality. Install MySQL:

sudo apt install mysql-server -y
sudo mysql_secure_installation

Follow the security script prompts to:

• Set a strong root password

• Remove anonymous users

• Disable remote root login

• Remove test database

Step 6: Install PHP

PHP enables dynamic content on your websites. Install PHP and essential modules:

sudo apt install php libapache2-mod-php php-mysql php-cli php-curl php-xml php-mbstring -y
sudo systemctl restart apache2

Step 7: Configure Virtual Hosts

Virtual hosts allow you to host multiple websites on one server. Create your first virtual host:

sudo mkdir -p /var/www/yourdomain.com/public_html
sudo chown -R $USER:$USER /var/www/yourdomain.com/public_html
sudo chmod -R 755 /var/www/yourdomain.com

Create a sample index.html file:

echo "<h1>Welcome to yourdomain.com!</h1>" | sudo tee /var/www/yourdomain.com/public_html/index.html

Step 8: Network Configuration

Configure your router for external access:

Port Forwarding:

• Forward port 80 (HTTP) to your server's internal IP

• Forward port 443 (HTTPS) to your server's internal IP

• Forward port 22 (SSH) for remote management (optional)

Dynamic DNS Setup:

If you don't have a static public IP, use a dynamic DNS service like No-IP or DuckDNS to maintain consistent domain access.

Step 9: SSL Certificate Installation

Secure your websites with free SSL certificates from Let's Encrypt:

sudo apt install certbot python3-certbot-apache -y
sudo certbot --apache -d yourdomain.com -d www.yourdomain.com

Set up automatic renewal:

sudo crontab -e

Add this line: 0 12 * * * /usr/bin/certbot renew --quiet

Security Best Practices

Essential Security Measures

Regular Updates: Keep your system updated with security patches:

sudo apt update && sudo apt upgrade -y

SSH Key Authentication: Disable password authentication and use SSH keys:

ssh-keygen -t rsa -b 4096 -C "[email protected]"

Fail2Ban Installation: Protect against brute force attacks:

sudo apt install fail2ban -y
sudo systemctl enable fail2ban

Advanced Security Configuration

Apache Security Headers: Add security headers to your Apache configuration:

sudo nano /etc/apache2/sites-available/000-default.conf

Add these headers inside the VirtualHost block:

Header always set X-Content-Type-Options "nosniff"
Header always set X-Frame-Options "SAMEORIGIN"
Header always set X-XSS-Protection "1; mode=block"

Common Mistakes and How to Avoid Them

Network Configuration Errors

Problem: Website not accessible from outside your network

Solution: Verify port forwarding rules in your router and check firewall settings. Ensure your domain points to your public IP address.

Permission Issues

Problem: “403 Forbidden” errors when accessing websites

Solution: Check file permissions and ownership:

sudo chown -R www-data:www-data /var/www/yourdomain.com/
sudo chmod -R 755 /var/www/yourdomain.com/

SSL Certificate Problems

Problem: SSL certificate not working or expired

Solution: Verify certificate renewal cron job and check domain DNS settings. Use sudo certbot certificates to check certificate status.

Performance Optimization Tips

Apache Performance Tuning

Optimize Apache for better performance:

sudo nano /etc/apache2/apache2.conf

Add these optimization settings:

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 5

Enable Compression

Enable Gzip compression to reduce bandwidth usage:

sudo a2enmod deflate
sudo systemctl restart apache2

Monitoring and Maintenance

Log Monitoring

Regularly check system and Apache logs:

sudo tail -f /var/log/apache2/access.log
sudo tail -f /var/log/apache2/error.log

Automated Backups

Create automated backup scripts for your websites and databases:

#!/bin/bash
mysqldump -u root -p your_database > /backup/db_backup_$(date +%Y%m%d).sql
tar -czf /backup/website_backup_$(date +%Y%m%d).tar.gz /var/www/
