Configuring Gunicorn

Install Gunicorn:
```
pip3 install gunicorn
```

Create a Gunicorn configuration file:

sudo nano /etc/systemd/system/gunicorn.service

Add the following configuration to the file:

[Unit]

```
Restart Nginx:
```
sudo systemctl restart nginx
```
Allow Nginx through the firewall:
```
sudo ufw allow 'Nginx Full'
```

Conclusion

You have successfully set up the Signup Flask app in a development environment using Gunicorn and Nginx.
