It is really not a good idea to run your CGI scripts as root. If someone comprosmises your web server they have won instant access to everything. If someone finds a bug in your program they can exploit it for root access. If your program misbehaves, it can damage anything. There's a reason most things don't run as root, and a reason webservers in particular get very little access to anything -- anyone in the world can cause a request to happen, and can inject any data they want with ease.
You could perhaps use sudo to allow your webserver to run very specific things as root, so you could do system("sudo /path/to/script.sh"); Don't give it a blank cheque. Only let it run very specific scripts, and write those scripts very carefully.

php5-fpm
PHP-FPM(8) Scripting Language PHP-FPM(8)
NAME
php-fpm - PHP FastCGI Process Manager 'PHP-FPM'
SYNOPSIS
php-fpm [options]
DESCRIPTION
PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. This
is a variant of PHP that will run in the background as a daemon, listening for CGI requests. Output is logged to /var/log/php-fpm.log.
Most options are set in the configuration file. The configuration file is /etc/php-fpm.conf. By default, php-fpm will respond to CGI
requests listening on localhost http port 9000. Therefore php-fpm expects your webserver to forward all requests for '.php' files to port
9000 and you should edit your webserver configuration file appropriately.
OPTIONS
-C Do not chdir to the script's directory
--php-ini path|file
-c path|file Look for php.ini file in the directory path or use the specified file
--no-php-ini
-n No php.ini file will be used
--define foo[=bar]
-d foo[=bar] Define INI entry foo with value bar
-e Generate extended information for debugger/profiler
--help
-h This help
--info
-i PHP information and configuration
--modules
-m Show compiled in modules
--version
-v Version number --prefix path
-p Specify alternative prefix path (the default is /usr)
--fpm-config file
-y Specify alternative path to FastCGI process manager configuration file (the default is /etc/php-fpm.conf)
--test
-t Test FPM configuration file and exit If called twice (-tt), the configuration is dumped before exiting.
--zend-extension file
-z file Load Zend extension file
FILES
php-fpm.conf The configuration file for the php-fpm daemon.
php.ini The standard php configuration file.
SIGNAL
Once started, php-fpm then responds to several POSIX signals:
SIGINT,SIGTERM immediate termination
SIGQUIT graceful stop
SIGUSR1 re-open log file
SIGUSR2 graceful reload of all workers + reload of fpm conf/binary
