figure out redundant fastcgi configuration files

[mehov]

• /etc/nginx/snippets/fastcgi-php.conf
• /etc/nginx/fastcgi.conf
• /etc/nginx/fastcgi_params

Nginx's fastcgi_params includes this right after SERVER_PROTOCOL:

fastcgi_param  REQUEST_SCHEME     $scheme;

And Debian's fastcgi.conf has

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

The fastcgi_params that comes from Debian repo has the least amount of features.

From what I understand, the Debian package maintainers wanted to avoid overwriting the default files that come with Nginx, so they had to come up with this approach. It appears that:

• fastcgi_params comes with Nginx and declares the variables that will be accessible as $_SERVER[...] in PHP
• fastcgi.conf comes with Debian, is mostly the same as the previous one, except it declares few more variables
• snippets/fastcgi-php.conf has security hotfixes and workarounds for wontfix issues like this one

On Nginx versions maintained by Debian, the fastcgi_params does not seem to be used at all, and it just sits there. Instead, the PHP configurations refer to snippets/fastcgi-php.conf which includes fastcgi.conf
