nginx运行时的error log：

FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream 原因在于nginx 默认的脚本配置中

location ~ \.php$ { 
    root html; fastcgi_pass 127.0.0.1:9000; 
    fastcgi_index index.php; 
    fastcgi_param SCRIPT_FILENAME /script$fastcgi_script_name; 
    include fastcgi_params; 
} 

SCRIPT_FILENAME 需要更新成实际的目录，修改如下：

$document_root$fastcgi_script_name;
