nginx and trailing slashes on $document_root?

Question

I use the following configuration for nginx: http://gist.github.com/340956

However, this configuration causes a No input file specified error with PHP. The only way I have been able to solve it is by altering this line:

fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;

Note the "/" between $document_root and $fastcgi_script_name. I was informed that this is the wrong configuration but no one has been able to tell me exactly why my configuration requires this extra slash.

How can I get rid of that extra slash?

Answer 1

Just faced the same issue (in remi installation of nginx+php-fpm on a RHEL6 server), you can solve it by adding the following line in /etc/nginx/fastcgi_params

fastcgi_param  SCRIPT_FILENAME    $request_filename;

I found this line missing in RHEL, while present in a perfectly working Debian nginx.

Answer 2

Does the param PATH_TRANSLATED get the correct URI? I'm thinking it's the immediate concatenating of the variables in the conf file that doesn't compute. When adding a slash between them, maybe they are interpreted correctly.

When you get the error No input file specified, check your log to see what URI was requested.
