I have developed a web application with Django and I am trying to publish it in a virtual machine created with Azure. To do that I'm using the following software stack:

  • Ubuntu (20.04)
  • Django (3.0.7)
  • Virtualenv (20.0.17)
  • Gunicorn (20.1.0)
  • Nginx (1.18.0)

To deploy the app I followed that guide: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04

My django project folders are organized as follows:

home/
├─ useradmin/
│  ├─ myproject/
│  │  ├─ proj/
│  │  │  ├─ settings.py
│  │  │  ├─ urls.py
│  │  │  ├─ wsgi.py
│  │  │  ├─ ...
│  │  ├─ static/
│  │  ├─ templates/
│  │  ├─ venv/
│  │  ├─ manage.py
│  │  ├─ ...

This is my /etc/systemd/system/gunicorn.service:

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=useradmin
Group=www-data
WorkingDirectory=/home/useradmin/myproject
ExecStart=/home/useradmin/myproject/venv/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/useradmin/myproject/myproject.sock proj.wsgi:application
[Install]
WantedBy=multi-user.target

This is my /etc/nginx/sites-available/myproject:

server {
    listen 80;
    server_name mydomain.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/useradmin/myproject;
    }

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

When I navigate to mydomain.com I get a 502 Bad Gateway error. If I check the Nginx logs by running "sudo tail -F /var/log/nginx/error.log" I see the following error:

2022/03/16 08:27:33 [crit] 64480#64480: *3 connect() to unix:/home/useradmin/myproject/myproject.sock failed (2: No such file or directory) while connecting to upstream, client: XX.XX.XX.XX, server: mydomain.com, request: "GET / HTTP/1.1", upstream: "http://unix:/home/useradmin/myproject/myproject.sock:/", host: "mydomain.com"

To create the sock file I run the following instructions but nothing changes:

systemctl daemon-reload
systemctl restart gunicorn.service

UPDATE 1:

Trying to execute the instruction ls -la /home/useradmin/myproject/myproject.sock I get the error ls: cannot access '/home/useradmin/myproject/myproject.sock': No such file or directory

django python nginx gunicorn 502

I created a web application on Azure consisting of a Virtual Machine and a PostgreSQL 10 database. I want to configure the Azure "Backup vault" service to periodically perform a database backup. So, I created the "Backup vault" service and the backup policy as explained in this video guide. However, at the end of the process, the validation of the selected databases fails with the following error:

  • Error code: UserErrorBackupUserAuthFailed
  • Message: Backup user authentication failed.
  • Recommendations: Configure appropriate permissions for the backup user as mentioned at https://aka.ms/osstroubleshooting.
  • DetailedNonLocalisedMessage: 28P01: password authentication failed for user "azure_backup"

After reading the "UserErrorBackupUserAuthFailed" chapter of the above guide, I set myself up as the Active Directory admin of the PostgreSQL database. However, the problem persists.

What I have:

  • A domain purchased in webs.com (I'll call it contoso.com);
  • A main website hosted in webs.com using contoso.com as dns (I didn't build and configure it by myself);
  • A second website (its purpose is to expose a new service offered by my company) hosted throught an Azure VM using IIS as web server;

What I want:

I would like to create a subdomain (e.g. sub.contoso.com) and link it with my second website. If possible, I wouldn't want to transfer the main website in Azure (it would be too time consuming and expensive at the moment) or the second website in webs.com (it's impossible) or buy a second domain.

What I've done:

To accomplish this I followed step by step this guide: https://docs.microsoft.com/en-us/azure/dns/delegate-subdomain

The problem:

The problem is that the "Test the delegation" step fail.

I'm not sure but I think that the problem is due to the Name Server list in webs.com. In fact here I found two Name Servers inserted by default by webs.com and, since they are necessary for the proper functioning of the main website, I only added the 4 Azure Name Servers.

I wrote to webs.com about this issue and they told me that at the moment it's not possible have the main web site hosted by them and a subdomain hosted by Azure.

Is there a workaround? For exemple, create an A record in Azure to link the main website and removing the 2 default Name Servers in webs.com
