reason:
in fastcgi_params file (and nginx.conf file in the same directory) defined in a number of variables associated with fastcgi program, when nginx fastcgi interface to send via it is requested to go to a defined place to resolve the corresponding variable value, and then to php to deal with, obviously, if fastcgi can not get the appropriate value, then he will not be able to forward the request to the corresponding php program, it can not resolve.
The key to this problem lies in "Primary script unknown" master script is unknown, which is defined fastcgi can not find the script to be executed, the default configuration file fastcgi_params defined variable and not $ fastcgi_script_name this variable, but defined in fastcgi.conf a. So we either include this fastcgi.conf file, or to construct the fastcgi_params in the SCRIPT_FILENAME and fastcgi.conf in the value of the same, plus $ document_root parameter (the value of the parameter represents the value of the site root directory that line).
Solution 1
in the last line of the configuration file that contains fastcgi.conf configuration, the following results
1 location ~ \.php$ {
2 root html/wordpress;
3 fastcgi_pass 127.0.0.1:9000;
4 fastcgi_index index.php;
5 fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
6 include fastcgi_params;
7 include fastcgi.conf;
8 }Solution 2
Ba fastcgi_param SCRIPT_FILENAME / scripts $ fastcgi_script_name; this line instead: fastcgi_param SCRIPT_FILENAME $ document_root $ fastcgi_script_name;
1 location ~ \.php$ {
2 root html/wordpress;
3 fastcgi_pass 127.0.0.1:9000;
4 fastcgi_index index.php;
5 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
6 include fastcgi_params;
7 }
