PHP-FPM Configuration

Basic PHP-FPM Setup

server {
    listen 80;
    server_name example.com;
    root /var/www/html;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php/php-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors on;
    }

    location ~ /\. {
        deny all;
    }
}

TCP vs Unix Socket

# Unix socket (preferred - faster)
location ~ \.php$ {
    fastcgi_pass unix:/var/run/php/php-fpm.sock;
}

# TCP socket (use for remote PHP-FPM)
location ~ \.php$ {
    fastcgi_pass 127.0.0.1:9000;
}
