Question

I use SetEnv in Apache to set some variables in virtualhosts that I recover in PHP using $_SERVER[the_variable].

Now I am switching to Perl Catalyst and

The fastcgi_pass socket location needs to come first, then each of the fastcgi_param parameters. You can also list variables in a file in the nginx config folder, then include that file. The include file commonly has the name fastcgi_params. Your environment parameters can be added easily to the php handling block:

        location ~ \.php$ {
            fastcgi_pass     unix:/your_sock_location/nginxFastCGI.sock;
            fastcgi_param    SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param    APP_ENV production;
            include          fastcgi_params;
        }

The fastcgi_params file located in the same directory as nginx.conf often looks like this:

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;
