Nginx PHP7.0-FPM没有这样的文件或目录

我让nginx正常工作，然后它突然在html文件夹上出现权限问题，所以我用

sudo chown-R www-data:www-data/var/www/html

但后来我开始对php7.0-fpm.sock产生问题 如果我尝试先加载页面，它会显示

无法连接 Firefox无法在5时与服务器建立连接。***.

然后有一半的时间我会这样：

连接已重置 加载页面时已重置与服务器的连接

在nginx的error.log中，我得到以下信息：

[crit]23274#23274:*6335 connect（）到unix:/var/run/php/php7.0-fpm.sock
连接到上游时失败（2：没有此类文件或目录）

通过运行

ls-l/var/run/php/php7.0-fpm.sock

我得到：

通过运行：

ls-l/var/www/html

我得到：

/etc/nginx/站点已启用/默认值：

更新：

尝试从chrome连接时出现错误404 not found，因此我查看了error.log，它显示权限问题，切换回root:root with chown，现在它再次显示php7.0-fpm的问题为not found

我最近在nginx中遇到了类似的错误

我就是这样解决的：

确认php fpm正在运行。在我的情况下，由于安装了某些模块，它正在重新启动。在fpm重新启动期间，nginx尝试连接，但fpm未运行

确保php fpm和nginx对套接字文件具有适当的权限

在我的例子中，我后来将php fpm从套接字切换到端口9000

---

希望这能有所帮助。

php fast process manager需要在创建套接字文件时运行。

systemctl status php7.0-fpm

是否表示进程处于活动状态？@castis active:active（running）并且您正在使用

sudo systemctl start nginx启动nginx

，对吗？@castis service nginx start/stoptry

sudo systemctl start nginx启动nginx
