I followed the DO article "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.
