 Ideally, you want to run each PHP-based service within the boundaries of it's own PHP instance. The advantages of such a solution would be that each PHP instance can run as the service user which guarantee service isolation and more protection in data access. Ideally, you want to run each PHP-based service within the boundaries of it's own PHP instance.

 +Your PHP FPM will still use the **php.ini** from the original setup folder, so delete the copied one or you will get confused!
  
 Then,  you need the following edit to your **/etc/init.d/php-fpm** script because, by default, your //service1// will be used as it was a PHP version but there is no PHP version numbered //service1//, so you need to separate the two things. The edit is simple, you need to split the PHP_SLOT variable to a PHP_SLOT_EXEC one that you can change. This approach will alow the __original__ way to still work while supporting also our __new__ way.

-==== Updating php ====+==== NGINX configuration ====
  
 +See [[selfhost:nginx|The Reverse Proxy concept]] for more datails on NGINX. 
  
 +A generic NGINX configuration for PHP-FPM is the following:
 +<code>
 +        location ~ /.*\.php$ {
 +                try_files $uri =404;
 +                fastcgi_split_path_info ^(.+\.php)(/.+)$;
 +                include fastcgi_params;
 +                fastcgi_param SCRIPT_FILENAME $request_filename;
 +                fastcgi_pass 127.0.0.1:9000;
 +        }
 +</code>
  
 +where you need to adapt the port (9000) and the location, of course.
 +
 +==== Updating php ====
  
 +When you perform emerge updates PHP will be updated sooner or later.
  
 +You can, and should, migrate to the newer version when possible. In this case all you need to do it to update the value into **php-version** and probably also update the specific //php.ini// values.
