Nginx－Primary script unknown的报错解决

报错：

[error] 12691#0: *6 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.168.1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "192.168.168.133"

在Nginx的conf中遭到定义脚本文件的地方：

fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;

修改成如下方式（$document_root）：

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

$document_root 代表当前请求在root指令中指定的值：

location / {
   root   /usr/local/nginx/html;
   index  index.php index.html index.htm;
       fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

上面配置中的$document_root就是针对/usr/local/nginx/html目录下的php文件进行解析。
