Adding Flask app in existing nginx PHP configuration - php

Question

The configuration below is the configuration for a web application in PHP, and it's working (I faked the site's name to https://sub.mysite.nl).
server {
listen [::]:443 ssl ipv6only=on; # managed by Certbot
listen 443 ssl; # managed by Certbot
## some certificate info ##
root /path/to/www;
index index.php index.htm index.html;
server_name sub.mysite.nl;
location / {
try_files $uri $uri/ =404;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /\.ht {
deny all;
}
## some logging info ##
}
server {
if ($host = sub.mysite.nl) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 default_server;
listen [::]:80 ipv6only=on default_server;
server_name sub.mysite.nl;
return 404; # managed by Certbot
}
Now I want to add a Flask app in a subfolder e.g. https://sub.mysite.nl/flaskapp.
The block below is what I got from the Flask Mega Tutorial I followed, see specifically this chapter: https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xvii-deployment-on-linux (under Setting Up Nginx). I think I need to put this under location /flaskapp/ but I'm not sure how to proceed, because when I do this and go to https://sub.mysite.com/flaskapp it gives me 404 Not Found.
location /flaskapp {
proxy_pass http://localhost:8000;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
Do I need to change the routing in my Flask app?

Answer 1

Ok, I've been fooling around a bit and it seems like editing the routes in my Flask app provides the easiest solution. For this, I use the Flask nginx block from my original post at the bottom.
So instead of #app.route('/'), I use #app.route('/flaskapp/').
And #app.route('/view_profile/<username>') becomes #app.route('/flaskapp/view_profile/<username>').
