Billrun on CentOS - PHP-FPM Configuration

HI, any unique details used for the PHP-FPM Configuration ?

user = <billrun_user>
group = <httpd_group>

I changed it to
user = root
group = root

Ran the command $ php -i | grep save_path
and got the response
session.save_path => no value => no value

Please review and advise
