Nginx 下载“*.php”而不是在 Docker 环境中显示它的内容

我正在运行PHP71 + Nginx的新 Docker 环境中工作。Dockerfile继承自million12/ docker -nginx。

这是/etc/nginx/hosts.d/vhost.conf（我从这里获取的）的内容：

server {
    listen      80  default_server;
    listen      81  default_server http2 proxy_protocol; ## Needed when behind HAProxy with SSL termination + HTTP/2 support
    listen      443 default_server ssl http2;

    ssl_certificate       /etc/nginx/ssl/dummy.crt;
    ssl_certificate_key   /etc/nginx/ssl/dummy.key;

    root        /data/www;
    index       index.php index.html index.htm;

    location ~ \.php$ {
        fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

    include     /etc/nginx/conf.d/stub-status.conf;
    include     /etc/nginx/conf.d/default-*.conf;
    include     /data/conf/nginx/conf.d/default-*.conf;
}

我找不到为什么下载文件而不是显示它的内容。

在容器内，这就是我所拥有的/var/run：

# ls -la /var/run/
total 8
drwxr-xr-x 11 root root 185 Dec 14 21:12 .
drwxr-xr-x 19 root root 299 Dec 14 21:12 ..
drwxr-xr-x  2 root root   6 Sep  5 10:19 blkid
drwxr-xr-x  2 root root   6 Jul 29 14:05 console
drwxr-xr-x  2 root root   6 Jul 29 14:05 faillock
drwxr-xr-x  4 root root  35 Jul 29 14:05 lock
drwxr-xr-x  2 root root   6 Jul 29 14:05 log
-rw-r--r--  1 root root   2 Dec 14 21:12 php-fpm.pid
drwxr-xr-x  2 root root   6 Jul 29 14:05 sepermit
drwxr-xr-x  2 root root   6 Jul 29 14:05 setrans
-rw-r--r--  1 root root   3 Dec 14 21:12 supervisord.pid
drwxr-xr-x  9 root root 113 Jul 29 14:05 systemd
drwxr-xr-x  2 root root   6 Jul 29 14:05 user
-rw-rw-r--  1 root utmp   0 Jul 29 14:05 utmp

也许这一行：

 fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;

工作不正常。将其更改为：

fastcgi_pass    php-upstream;

在哪里php-upstream：

upstream php-upstream {
    server 127.0.0.1:9000;
}

也不行。我被困在这一点上。在打开另一个新帖子之前，我已经检查了所有这些帖子：

• https://stackoverflow.com/questions/39950129/nginx-doesnt-serve-php-files（这是我前段时间打开的）
• https://stackoverflow.com/questions/21103328/nginx-downloads-php-instead-of-running-it

• https://stackoverflow.com/questions/20668886/nginx-and-fastcgi-downloads-php-files-instead-of-processing-them
• 在 Fedora 25/24、CentOS/RHEL 7.2/6.8 上安装 Nginx/PHP-FPM

任何人都可以给我一些帮助吗？请记住，所有这些都在 Docker 容器中运行，因此可能某些命令不可用。
