How to specify the PHP-FPM socket or port in Nginx configuration?

To specify the PHP-FPM socket or port in Nginx configuration, you need to make changes to your Nginx virtual host configuration file. Here's how to do it:

1. Open the Nginx configuration file for your virtual host. This file is usually located at /etc/nginx/sites-available/<your_site_name>.

2. Inside the server block, locate the following line:

   location ~ \.php$ {

3. Add the following lines after the location block:

   For PHP-FPM socket:

   fastcgi_pass unix:/path/to/php-fpm.sock;

   Replace /path/to/php-fpm.sock with the actual path of your PHP-FPM socket file. For example, it could be /run/php/php7.4-fpm.sock or /var/run/php/php7.4-fpm.sock.

   For PHP-FPM port:

   fastcgi_pass 127.0.0.1:9000;

   Replace 127.0.0.1:9000 with the actual IP address and port of your PHP-FPM server. By default, PHP-FPM listens on port 9000.

4. Save the configuration file and exit the editor.

5. Test the Nginx configuration for syntax errors using the following command:

   sudo nginx -t

   If there are no errors, proceed to reload Nginx to apply the changes:

   sudo systemctl reload nginx

   If there are errors, double-check your configuration file for typos or incorrect paths.

Now, Nginx will forward PHP requests to PHP-FPM using the specified socket or port.
