In this video, I will show you how you can deploy your Python Flask application on an Ubuntu VPS, using Gunicorn and Nginx. Since I don't have a spare VPS, I spun up a virtual machine running Ubuntu server and used that. But the steps would be the same if you were using an Ubuntu server VPS.

thank you very much! I've been trying to do this for 3 days now, and your tutorial is the only one that worked for me.

@vat1980 2 года назад

Really want to say thank you so much. Many tutorials end up in error but this one is spot on! Got my Flask app running on AWS ES2 in less than 15 mins. Great video.

Been banging my head against the wall from lots of other tutorials, this was the only one to work for me all the way through, and I have quite a large/complex Flask App. Thank you so much

I don't really comment on many videos, but this was a brilliant tutorial. I've been looking at so many tutorials, but there was always an error with them, if it wasn't nginx it was apache2. Thank you for the quick and clear explanation. Keep doing videos like these!

@devguyahnaf 2 года назад

Thanks a lot for your kind words. I really appreciate them :) Also, one thing I would like you to know is that Apache is a threaded server, which means it is prone to DDOS and DOS attacks. But Nginx on the other hand is an asynchronous web server and reverse proxy, so it is not as vulnerable as Apache, and it is also very easy to set up.

@AdrienZier Год назад

Great tutorial! Just wondering what's the use of the 2 lines under proxy_pass? the header forwarding. what does that achieve? many thanks!!

@devguyahnaf Год назад

Sorry for the late reply. All it does is provide the Flask app with some headers that contain the actual client information. This might be important for IP logging, or other analytical stuff in your application, since Flask doesn't directly get the client's info as it gets proxied by Nginx

@nicoxvxv 2 года назад

So i followed the tutorial, but i have a little problem. After running "gunicorn --workers=3 app:app" the main ip of my server is showing "Bad Gateway" and i dont know what i did wrong.

@devguyahnaf 2 года назад

The reverse proxy (Nginx in this case) is probably trying to find the gunicorn server on a specified port, but the server is not on that port. By default, the gunicorn server listens on port 8000, so your Nginx proxy would have to forward the requests to 127.0.0.1:8000. You would have the config sorta like this: location / { proxy_pass 127.0.0.1:8000; } This will load balance all the requests sent to your nginx server (through the main IP) and forward it to the gunicorn server so that people can access your flask application

Yes, flask app runs fine in local host

Hey Dev, i'm here again, but now it is another question about "gunicorn3 --workers=3 file:app". In my situation, a have a function Main and my app flask is inside this Function Main, and when i try to call the App with gunicorn, the server return for me saying I'm trying to pass two parameters when Main requires 0. How can I refer this app flask inside the Main who is inside the file?
