sudo dnf install -y httpd httpd-tools mod_ssl mod_rewrite

# Enable and start Apache
sudo systemctl enable httpd
sudo systemctl start httpd

# Check Apache status
sudo systemctl status httpd

# Configure firewall for web traffic
sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --permanent --add-service=https
sudo firewall-cmd --reload

# Create main Apache configuration backup
sudo cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.backup

# Configure main Apache settings
sudo tee /etc/httpd/conf.d/00-main.conf << 'EOF'
# Main Apache Configuration Optimizations

Perfect! Apache is up and running! 🎉

🔧 Step 2: Configure Virtual Hosts in Apache

Let’s set up virtual hosts for multiple websites:

# Create virtual hosts directory structure
sudo mkdir -p /var/www/{example.com,test.local}/{public_html,logs}

# Create virtual host configurations
sudo tee /etc/httpd/conf.d/example.com.conf << 'EOF'
<VirtualHost *:80>
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/public_html
    ErrorLog /var/www/example.com/logs/error.log
    CustomLog /var/www/example.com/logs/access.log combined

    # Security settings
    <Directory "/var/www/example.com/public_html">
        Options -Indexes +FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    # Hide sensitive files
    <FilesMatch "^\.">
        Require all denied
    </FilesMatch>

    # Prevent access to backup files
    <FilesMatch "\.(bak|backup|old|tmp)$">
        Require all denied
    </FilesMatch>
</VirtualHost>

<VirtualHost *:443>
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/public_html
    ErrorLog /var/www/example.com/logs/ssl_error.log
    CustomLog /var/www/example.com/logs/ssl_access.log combined

    # SSL Configuration (will be added when certificate is ready)
    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/example.com/cert.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
    SSLCertificateChainFile /etc/letsencrypt/live/example.com/chain.pem

    # Security headers for HTTPS
    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"

    <Directory "/var/www/example.com/public_html">
        Options -Indexes +FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
EOF

# Create sample content for virtual host
sudo tee /var/www/example.com/public_html/index.html << 'EOF'
<!DOCTYPE html>

        .info { background: #e7f3ff; padding: 15px; border-radius: 5px; margin: 20px 0; }
    </style>
</head>
<body>
    <div class="container">
        <h1 class="success">🌐 Virtual Host Working!</h1>
        <p>This is the <strong>example.com</strong> virtual host running on Apache.</p>

        <div class="info">
            <h3>📋 Site Information:</h3>

# Set proper permissions
sudo chown -R apache:apache /var/www/example.com
sudo chmod -R 755 /var/www/example.com

# Test and reload Apache
sudo httpd -t
sudo systemctl reload httpd

Excellent! Virtual hosts are configured! 🌟

🌟 Step 3: Install and Configure Nginx

Now let’s set up Nginx as an alternative or complement to Apache:

# Install Nginx
sudo dnf install -y nginx

# Enable and start Nginx (stop Apache first if needed)
# sudo systemctl stop httpd
sudo systemctl enable nginx
sudo systemctl start nginx

# Check Nginx status
sudo systemctl status nginx

# Backup original Nginx configuration
sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.backup

# Configure optimized Nginx settings
sudo tee /etc/nginx/nginx.conf << 'EOF'

✅ Step 4: SSL/TLS Configuration with Let’s Encrypt

Let’s secure our web servers with free SSL certificates:

# Install Certbot for Let's Encrypt
sudo dnf install -y certbot

# For Apache
sudo dnf install -y python3-certbot-apache

# For Nginx
sudo dnf install -y python3-certbot-nginx

# Create SSL certificate management script

    elif [ "$WEBSERVER" = "nginx" ]; then
        sudo certbot --nginx -d $DOMAIN -m $EMAIL --agree-tos --non-interactive
    else
        echo "Invalid web server specified"
        return 1
    fi

    echo "✅ SSL certificate installed successfully!"
}

renew_certificates() {
    echo "🔄 Renewing SSL certificates..."
    sudo certbot renew --dry-run

    if [ $? -eq 0 ]; then
        echo "✅ Certificate renewal test successful!"
        sudo certbot renew
    else
        echo "❌ Certificate renewal failed!"
    fi
}

list_certificates() {
    echo "📋 Installed SSL Certificates:"
    sudo certbot certificates
}

case "$1" in

🚨 Fix Common Problems

Problem 1: Apache/Nginx Won’t Start

# Check configuration syntax
sudo httpd -t  # For Apache
sudo nginx -t  # For Nginx

# Check for port conflicts
sudo ss -tuln | grep :80

# Check logs for errors
sudo journalctl -u httpd -n 20  # Apache
sudo journalctl -u nginx -n 20  # Nginx

# Fix common permission issues
sudo setsebool -P httpd_can_network_connect 1
sudo chown -R apache:apache /var/www/  # Apache
sudo chown -R nginx:nginx /usr/share/nginx/  # Nginx

Problem 2: SSL Certificate Issues

# Check SSL certificate status
sudo certbot certificates

# Test SSL renewal
sudo certbot renew --dry-run

# Fix certificate permissions
sudo chmod 600 /etc/letsencrypt/live/*/privkey.pem

# Regenerate certificate if needed
sudo certbot delete --cert-name domain.com
sudo certbot --apache -d domain.com  # or --nginx

Problem 3: Poor Performance

# Check system resources
htop
iostat -x 1 5

# Optimize Apache/Nginx worker processes
# For Apache:
echo "MaxRequestWorkers 400" >> /etc/httpd/conf.d/performance.conf

# For Nginx:
sed -i 's/worker_processes auto;/worker_processes 4;/' /etc/nginx/nginx.conf

# Enable caching
# Add to Nginx:
echo "proxy_cache_path /tmp/cache levels=1:2 keys_zone=my_cache:10m max_size=10g inactive=60m;" >> /etc/nginx/nginx.conf
