After adding fastcgi support to nginx, verify the PHP page and report an error file not found. Check the log display

FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream,

At first, I thought it was a permission problem, so I started to configure it first

location  ~ \.php$ {
          root  /data/nginx/html/php;
          default_type text/html;
          fastcgi_pass  127.0.0.1:9000;
          fastcgi_index  index.php;
          #fastcgi_param  SCRIPT_FILENAME /data/nginx/php$fastcgi_script_name;
          fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;   //error
          fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
          include  fastcgi_params;
       }

It looks like the configuration is the same, in fact, there is a w problem here, I am a direct copy of win to linux,, using nginx -t file is OK, not detected at all, you can download the WinMerge file to compare the upper and lower lines, you can also cat -A detect win spaces.
