Nginx访问PHP文件的File not found

这个错误很常见，原有有下面两面几种

    1. php-fpm找不到SCRIPT_FILENAME里执行的php文件
    1. php-fpm不能访问所执行的php，也就是权限问题
第一种情况

更改配置文件nginx.conf

1
fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

替换成下面

1
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

然后重新加载nginx配置文件

1
/etc/init.d/nginx reload

第二种情况

两种解决方法：
第一种，就是把你root文件夹设为其他用户允许
第二种，找到你的php-fpm的配置文件，找到下面这段，把apache替换成你要的用户组

; RPM: apache Choosed to be able to access some dir as httpd 
user = apache 
; RPM: Keep a group allowed to write in log dir. 
group = apache
