How to give permission to nginx?

Question

Nginx

I'm making a python flask web application using gunicorn, uwsgi, nginx. The application works, but the problem is with nginx. I did it using the forum . At step 5, I did everything correctly, but I looked at the logs and there is an error

2020/05/28 15:17:11 [crit] 318#318: *1 connect() to unix:/root/myproject/myproject.sock failed (13: Permission denied) while connecting to upstream, client: "тут айпи", server: "тут сервер", request: "GET / HTTP/1.1", upstream: "http://unix:/root/myproject/myproject.sock:/", host: "тут хост"

myproject

server {
    listen 80;
    server_name "тут домен" "www.тут домен";

    location / {
        include proxy_params;
        proxy_pass http://unix:/root/myproject/myproject.sock;
    }
}

myproject.sock

[Unit]
Description=Gunicorn instance to serve myproject
After=network.target

[Service]
User=sammy
Group=www-data
WorkingDirectory=/root/myproject
Environment="PATH=/root/myproject/myprojectvenv/bin"
ExecStart=/root/myproject/myprojectvenv/bin/gunicorn --workers 3 --bind unix:myproject.sock -m 007 wsgi:app

[Install]
WantedBy=multi-user.target

How to fix the error?

Answer 1

Well, firstly - do not work as a root. Never.
Secondly, without touching the horror ( proxy_pass http://unix:/root/myproject/myproject.sock; ), which is written in your config, even if you raise the socket in the root folder, the web server does not have access there.

Answer 2

The problem is the lack of necessary access for nginx. We recommend that you familiarize yourself with similar cases:
