5:49 - Create a VirtualHost config file
8:16 - Enable the new VirtualHost config
8:53 - Install the WSGI Apache module

👋🏻 Hey! Do you like Python? Web app development? Automation?! Let me know what topics you'd like to see me cover next! 😃

This was awesome! I just built my very first flask app (actually my first web page) and wanted to try to deploy what I have next week for testing. Even without seeing the file structure of the server, I understood what you were explaining so I'm pretty confident. Thank you!

Great vid. Thanks for including the troubleshoots. This is just what I needed for deploying my first flask app to a container. it’s awesome that it’s running on Apache because that makes the letsencrypt certificate renewals that much easier as well!

I was trying to implement an API on my VPS and you helped me in 11:20 minutes more than any other source of information in 8 days of trying.

Thx !!! i've been trying for a long time to deploy my flask app into digitalocean ubuntu server, only after use your config code (10:22) it worked.

[Turjak_art]

Thank you. It is ridiculous what we need to do in order to solve such a simple task. Shame that in all those years of internet they never came to a better and simpler solution.

Thanks for the great tutorial! I know literally nothing about linux or apache and I still got it to work on my raspberry pi thanks to you

Thank you, this video helped fixing an error in my configuration!

👍The Perfect Tutorial! 👍 I am already comfortable with Apache and virtual domains and just needed a quick run through for hosting Python apps. The only thing that would make it better would be having a guthub repo with your project files. Excellent video, thank you.

[Richard_GIS]

The first useful tutorial at all for this usecase! Thy.

[vincenta]

Hey luke. Thanks for the video.
How did you chnage your terminal color? The colors looks very pleasing! Are you using iterm and omz? What is the theme? 😅

[vijayyajurvedi]

I have centos 7 os there is no ditectory as var/www for apache but httpd service is enabled. Also there is no site enable command to enable it . Please guide.

Hi, using old version of linux mint, but for every step I take something goes wrong... why would this be happening? For instance I get pkg_resources cannot be imported, when I've written "pip install setuptools" 100 times

[XChristosK]

Hi, very good tutorial. Everything running fine.
I notice that if i change the home.html the content change only of i refresh apache.
can you provide a solution to that ?

I have already add
WSGIScriptReloading On
on virtual site but it didnt work.

Thanks
