I've followed the series in this and learned quite a bit about flask. Just a quick note that if you are "root" you don't need to type sudo. A security tutorial would be great because there are many things that can be improved on this section. Otherwise, great work, great explanations!

This series is great. One comment, at around 16:00, you mention that for nano the exit command for Macs can be Ctrl+X or Cmd+X, which isn't correct. You have to use Ctrl+X. Same with all nano commands, need to use Ctrl. I've learned a lot from your series! Keep it up.

@SpooningTreesap86 3 года назад

Does anybody know if this will work if I deploy my flask app (which is a simple REST API to handle incoming POST requests only) using this method but then reference the server IP from my front end which is on a separate server? Meaning I have a single page html/JS page which enables an AJAX post request that successfully is handled by flask on a separate server? In practice I have it working putting my flask app on loaclhost port 5000 and my front end on port 5500. The only part that concerns me is how the templates folder is required, yet I won't be displaying any html from this server.

I'm not sure what you're talking about but if you mean the contents of "/var/www/webApp/webApp" folder that's the flask app. this video was about running a flask app on Apache remember? so you need to have an app to run. that's the one.

@jakemayr1 3 года назад

@@mohammadfallah.rasoulnejad5379 In his past tutorials he didn't go over the __init__.py or setup.py files, just his main flask file so I was wondering about that part of the setup. This video is a part of a series he did as he mentions at the beginning of the video :)

@fvgoya 4 года назад

So, if we use Flask (Python), we will always need to have APACHE (which is manly to run PHP) to run Flask? Does not exist a server for Python, like Apache for PHP or Node for JavaScript??

@Asmayra 4 года назад

The more common approach would be to use gunicorn as a webserver and nginx as a reverse proxy. Miguel Grinberg has a good guide on this in his Flask Mega Tutorial (Chapter 17).

@jermeekable 4 года назад

I like what you are doing but id like to know the cli way all the way through. Copy Pasta in gui to get files on ur server is not as useful as knowing how to pull from git for instance. Anyways thanks for the vids, they are helpful. I have been digging youtube for weeks for good ubuntu server vids. Good ones are rare. Most I find are one off vids on how to install ubuntu server or terminal basics. I really hope you fill the niche. Ive only found two other playlists that get beyond basics helpful. But this is the only one ive seen touch flask. I managed to deploy a flask app to my server with gunicorn but dont know the diff between what I did n using apache. Or how to set up postgres locally on the server and connect to it. I guess I will just read what I need to know when the time comes but would much rather learn about it by watching a dope youtube lecture!!!

Great tutorial - I ran into an issue on the winSCP part of moving files to the directory. Reason : lack of privileges and needing root. winSCP can inject a shell command at the point of connection under the Advanced setting within the session configuration. click Advanced then under the Environment > SCP/Shell option add the command to the shell: field in this case 'sudo su -' (this elevates the user id to root privileges at point of connection.)
