'no input file specified' on LEMP setup

[mottwsc]

I followed the article "How to Install Linux, nginx, MySQL, PHP (LEMP) stack
on CentOS 6"
(https://www.digitalocean.com/community/articles/how-to-install-linux-nginx-mysql-php-lemp-stack-on-centos-6)
and could see the nginx default page displayed. After I worked through the
changes to configs, etc. and tried to display info.php (phpinfo), I get the
message 'no input file specified'. I get that same thing on another php file
that I loaded to the site in the same directory. However, I can display an
html file from that directory.

Any thoughts as to how to track this down?

Thanks.
