How to Solve “No input file specified” with PHP and Nginx

The root cause of the error is that PHP cannot find the file Nginx is telling it to look for, and there are a few common cases that causes this.

Sadly, while many people will optimize their software stack they will rarely work on optimizing the back-end code; and even more rarely will they eliminate single points of failure.
