How to configure Nginx to handle PHP-FPM authorization and access control?

To configure Nginx to handle PHP-FPM authorization and access control, you can follow these steps:

Make sure that both Nginx and PHP-FPM are installed and running on your server.
Open your Nginx configuration file using a text editor. The location of this file may vary depending on your operating system and Nginx installation, but common locations include /etc/nginx/nginx.conf or /etc/nginx/conf.d/default.conf.
Within the http block of your Nginx configuration file, add the following lines to define a PHP-FPM resource and set up authorization and access control:

http {
  # ... other configuration directives ...

  fastcgi_pass unix:/run/php/php-fpm.sock;
  fastcgi_index index.php;
  fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
  
  # Define authorization and access control
  location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    include fastcgi_params;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    fastcgi_param  PATH_INFO        $fastcgi_path_info;
    
    # Define access control rules
    allow 192.168.0.0/24;
    deny all;
  }

  # ... other configuration directives ...
}

Customize the fastcgi_pass directive based on your PHP-FPM configuration. The example uses the default Unix socket path for PHP-FPM but you may need to change it if your setup is different.
Customize the location block to match your requirements. In this example, it allows access to PHP files only and restricts access to all other files.
Customize the allow and deny directives to define your access control rules. In the example, it allows access from the 192.168.0.0/24 subnet and denies access to other IP addresses.
Save the changes to your Nginx configuration file and restart the Nginx service to apply the new configuration. The command to restart Nginx varies depending on your operating system, but common options include service nginx restart or systemctl restart nginx.

Once these steps are completed, Nginx will handle authorization and access control for PHP-FPM scripts based on the rules you defined.
