PHP-FPM Integration driving me mad

[Simon Hönscheid]

Hello List,

due to a Server move, I was setting up a new nginx installation. Some of 
the pages need php. So far nothing new. When I start adding 
SCRIPT_FILENAME to the php location, it ends up that the script is no 
longer found.


==> /var/log/nginx/www.example.com-error.log <==
2016/07/30 21:21:15 [error] 5546#5546: *1 FastCGI sent in stderr: 
"Primary script unknown" while reading response header from upstream, 
client: xx.xxx.xxx.xxx, server: www.example.com, request: "GET /info.php 
HTTP/1.1", upstream: "fastcgi://unix:/var/run/fpmpool-www.socket:", 
host: "www.example.com"

Do I leave it out, the script is handled but no output is retuned.(blank 
white page) I'm debugging this now for hours and dont get any usable 
result. Any help is appreciated.
