nginx-未指定输入文件。拉维应用

Question

这是Ubuntu 16.04中的nginx配置文件。4 LTS：

server {
    listen 80 default_server;

    root /var/www/html/public;
    index index.html index.htm index.php;
    server_name _;

        location / {
            try_files $uri $uri/ /index.php?$query_string;
        }

        location ~ \.php$ {

                fastcgi_pass unix:/var/run/php/site.com.sock;
                fastcgi_param SCRIPT_FILENAME 
                $document_root$fastcgi_script_name;
                include fastcgi_params;
                include snippets/fastcgi-php.conf;
        }

}

当访问网站我得到：没有输入文件指定。

存在/var/run/php/site.com.sock：

root MainTest /var/run/php ls -la /var/run/php/
total 4
drwxr-xr-x  2 www-data www-data   80 Dec 28 19:22 .
drwxr-xr-x 27 root     root     1080 Dec 28 21:54 ..
srw-rw----  1 www-data www-data    0 Dec 28 19:22 site.com.sock
-rw-r--r--  1 root     root        5 Dec 28 19:22 php7.2-fpm.pid

这是 /var/log/nginx/error.log

*7在stderr中发送的FastCGI：“无法打开主脚本：/var/www/html/public/index.php（没有这样的文件或目录）”，同时从上游读取响应头，客户端：xx。xxx。xx。xxx，服务器：\请求：“GET/HTTP/1.1”，上游：fastcgi://unix:/var/run/php/site.com.sock:，主机：“xxx.xx.xxx.xxx”

指数php在/var/www/html/public中/

/var/www/html/public$ ll
total 44
drwxrwxr--  3 www-data www-data 4096 Dec 28 21:49 ./

nginx正在运行

我已经详细阅读了每一行代码，但没有发现任何东西，希望有人能看到这个问题。

谢谢。

你能证实 /var/www/html/public/.有index.php那是一个不标准的根。您还可以验证用户nginx正在运行，因为它可以访问该文件夹吗
