Question

我正在Degitalocean Ubuntu nginx服务器上运行我的Flask应用程序。我正在使用gunix运行我的应用程序。我已完成此博客中介绍的步骤： https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-18-04

但是systemctl status chatleads-nlu说它是活动的：

● chatleads-nlu.service - Gunicorn instance to serve chatleads-nlu

但是sudo less /var/log/nginx/error.log说它无法连接到上游：

2019/12/10 06:38:10 [crit] 3042#3042: *1075 connect() to unix:/root/chatleads-nlu/chatleads-nlu.sock failed (13: Permission denied) while connecting to upstream, client: 27.147.155.252, server: nlp.chatleads.io, request: "GET / HTTP/1.1", upstream: "http://unix:/root/chatleads-nlu/chatleads-nlu.sock:/", host: "nlp.chatleads.io:8888"

这是我的/etc/nginx/sites-available/digitalocean。

server {
        listen 8888;
        listen [::]:8888;
        server_name nlp.chatleads.io www.nlp.chatleads.io;
        # root /var/www/html;
        # index index.html index.htm;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        # try_files $uri $uri/ =404;
        proxy_pass http://unix:/root/chatleads-nlu/chatleads-nlu.sock;
        # proxy_pass http://127.0.0.1:5151;
        proxy_http_version 1.1;
        proxy_read_timeout 300;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules
        }

    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        proxy_pass http://localhost:5151;
    }
}

这已链接到/etc/nginx/sites-enabled。

这是我的应用程序文件的权限：

-rw-r--r-- 1 root root      717 Dec  9 05:33 README.md
drwxr-xr-x 2 root root     4096 Dec  9 10:19 __pycache__

-rw-r--r-- 1 root root       88 Dec  9 10:15 wsgi.py

我几乎尝试了所有方法，但无法找出问题所在。任何帮助将不胜感激。

systemctl staus处于活动状态，但.sock无法连接到上游
