Nginx PHP7.0-FPM没有这样的文件或目录Ubuntu

我有nginx工作正常，然后突然它开始在html文件夹上有权限问题，所以我编辑了权限

sudo chown -R www-data:www-data /var/www/html 但后来我开始遇到php7.0-fpm.sock的问题如果我首先尝试加载页面它说

无法连接Firefox无法在5 .. **** Build 与服务器的连接..

然后有一半时间我得到这个：

重置连接在页面加载时重置了与服务器的连接 .

在nginx的error.log中我得到了这个：

[暴击] 23274＃23274：* 6335 connect（）到unix：/var/run/php/php7.0-fpm.sock失败（2：没有这样的文件或目录）连接到上游

通过运行 ls -l /var/run/php/php7.0-fpm.sock 我得到：

srw-rw---- 1 www-data www-data 0 Jun  5 13:37 /var/run/php/php7.0-fpm.sock

通过运行： ls -l /var/www/html 我得到：

-rw-r--r--  1 www-data www-data  108850 Jan 28 09:01 stuff.php

在/ etc / nginx的/网站启用/默认：
