📝 Step 1: Installing Nginx and PHP-FPM

Let’s get the dream team installed! First Nginx, then PHP-FPM - they work together like peanut butter and jelly! 🥪

# Update system first (always start fresh!)
sudo dnf update -y

# Install Nginx (our web server superhero)
sudo dnf install nginx -y

# Install PHP and PHP-FPM (our processing powerhouse)
sudo dnf install php php-fpm php-mysqlnd php-curl php-gd php-xml php-mbstring php-json -y

# Start and enable services (make them run automatically!)
sudo systemctl start nginx
sudo systemctl enable nginx
sudo systemctl start php-fpm
sudo systemctl enable php-fpm

# Check if everything is running perfectly
sudo systemctl status nginx
sudo systemctl status php-fpm

echo "🎉 Nginx and PHP-FPM installed and running!"

🌟 Great job! Your web server foundation is solid as a rock!

🔧 Step 2: Configuring PHP-FPM for Maximum Performance

PHP-FPM is like a smart factory manager - let’s configure it to handle your workload perfectly:

# Edit the main PHP-FPM configuration
sudo nano /etc/php-fpm.conf

# Key settings to verify (these are usually good defaults):
# emergency_restart_threshold = 10
# emergency_restart_interval = 1m
# process_control_timeout = 10s

# Now configure the www pool (this is where the magic happens!)
sudo nano /etc/php-fpm.d/www.conf

Here’s your optimal PHP-FPM pool configuration:

; === PHP-FPM Pool Configuration for High Performance ===

[www]
; User and group for security (run as nginx user)
user = nginx
group = nginx

; How PHP-FPM listens (socket is faster than TCP)
listen = /run/php-fpm/www.sock
listen.owner = nginx
listen.group = nginx
listen.mode = 0660

; Process management (dynamic scaling - smart and efficient!)
pm = dynamic
pm.max_children = 50          ; Maximum number of child processes
pm.start_servers = 5          ; Number of child processes created on startup
pm.min_spare_servers = 5      ; Minimum number of idle servers
pm.max_spare_servers = 35     ; Maximum number of idle servers
pm.max_requests = 1000        ; Restart workers after handling this many requests

; Performance and memory settings
request_terminate_timeout = 300     ; Kill long-running scripts
rlimit_files = 4096                ; Maximum open files per process

; Security settings (protect your server!)
security.limit_extensions = .php   ; Only process .php files
php_admin_value[disable_functions] = exec,passthru,shell_exec,system
php_admin_flag[allow_url_fopen] = off

# Restart PHP-FPM to apply new configuration
sudo systemctl restart php-fpm

# Verify PHP-FPM is listening on socket
sudo ls -la /run/php-fpm/www.sock
# You should see the socket file!

echo "🔧 PHP-FPM optimally configured!"

💡 Pro Tip: The socket connection is faster than TCP for local communication!

🌟 Step 3: Configuring Nginx to Work with PHP-FPM

Now let’s teach Nginx to talk to PHP-FPM like best friends! This is where the magic happens:

# Create a new server block for your website
sudo nano /etc/nginx/conf.d/your-site.conf

Here’s your high-performance Nginx configuration:

# === High-Performance Nginx + PHP-FPM Configuration ===

server {
    listen 80;
    listen [::]:80;
    server_name your-domain.com www.your-domain.com;
    root /var/www/html/your-site;
    index index.php index.html index.htm;

    # Security headers (protect your visitors!)
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-XSS-Protection "1; mode=block" always;

    # Optimize static file serving (super fast!)
    location ~* \.(jpg|jpeg|png|gif|ico|css|js|pdf|zip)$ {
        expires 1y;
        add_header Cache-Control "public, immutable";
        access_log off;
    }

    # Main location block (handles all requests)
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    # PHP processing (the secret sauce!)
    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        
        # Connect to PHP-FPM via socket (blazing fast!)
        fastcgi_pass unix:/run/php-fpm/www.sock;
        fastcgi_index index.php;
        
        # FastCGI parameters for perfect communication
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        
        # Performance optimizations
        fastcgi_param PHP_VALUE "upload_max_filesize=50M \n post_max_size=50M";
        fastcgi_connect_timeout 60;
        fastcgi_send_timeout 60;
        fastcgi_read_timeout 60;
        fastcgi_buffer_size 128k;
        fastcgi_buffers 4 256k;
        fastcgi_busy_buffers_size 256k;
    }

    # Deny access to sensitive files (security first!)
    location ~ /\.ht {
        deny all;
    }
    
    location ~ /\.git {
        deny all;
    }
}

# Test Nginx configuration (catch errors before they cause problems!)
sudo nginx -t

# If test passes, reload Nginx
sudo systemctl reload nginx

echo "🌐 Nginx configured for PHP-FPM perfection!"

✅ Step 4: Creating a Website Directory and Test Files

Let’s create your website home and test that everything works perfectly:

# Create website directory structure
sudo mkdir -p /var/www/html/your-site

# Set proper ownership (nginx user needs access!)
sudo chown -R nginx:nginx /var/www/html/your-site
sudo chmod -R 755 /var/www/html/your-site

# Create a PHP info file to test configuration
sudo tee /var/www/html/your-site/info.php << 'EOF'
<?php
// PHP Configuration Information
phpinfo();
?>
EOF

# Create a simple test file to verify PHP processing
sudo tee /var/www/html/your-site/index.php << 'EOF'
