I am not able to find "cgi.fix_pathinfo" in my php.ini file (sudo nano /etc/php5/fpm/php.ini) after running the "sudo apt-get install php5-fpm php5-mysql" when configure the PHP Processor in LEMP (Ubuntu 14.04) according to [https://www.digitalocean.com/community/tutorials/how-to-install-linux-nginx-mysql-php-lemp-stack-on-ubuntu-14-04#step-three-—-install-php-for-processing](http://)

Why is this happening and how to solve this?

Appreciate with all your help.
