Nginx FastCGI PHP

We can see this comment in nginx.conf.

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

Means: When the nginx handle PHP, the server need to run FastCGI server.

so Before starting the nginx,we should run FastCGI first.

/PHPROOT/php-cgi.exe -b 127.0.0.1:9000

There is no magic. You have to run the server what the nginx need.
