Serve static files through Nginx and uwsgi - python

I'm struggling to let Nginx serve static files and tried out about every configuration option I could find. Here's the app's basic structure.
ROOT
|_ static
|_css/
|_js/
|_ app.py
I've read Nginx docs about it, but the files do not seem to cache.
Here's my /etc/nginx/nginx.conf:
user www-data;
events {
worker_connections 64;
}
http {
gzip on; # Enables compression
gzip_types
"application/javascript;charset=utf-8" application/javascript text/javascript
"text/css;charset=utf-8" text/css
"text/plain;charset=utf-8" text/plain;
server {
listen 80;
server_name www.domain.tk domain.tk;
location /static/ {
alias /home/myuser/myapp/static/;
add_header Cache-Control public;
expires 14d;
access_log off;
}
location / {
include uwsgi_params;
uwsgi_pass unix:/home/myuser/myapp/myapp.sock; # REPLACE user
}
}
}
I'm using a uWSGI server and a Flask application if that matters. The developer console says the app should leverage Browser caching, how do I configure Nginx to work with serving the static files?

Deploying Gunicorn using subpath in NGINX

According to this tutorial, there is section below that says this.
You must now configure your web proxy to send traffic to the new Gunicorn socket. Edit your nginx.conf to include the following:
/etc/nginx/nginx.conf:
...
http {
server {
listen 8000;
server_name 127.0.0.1;
location / {
proxy_pass http://unix:/run/gunicorn/socket;
}
}
}
...
What I want to do is use location /mysubpath. How should I do it?
I'm using mysubpath since I have 2 different projects running on the same server.
Something like this.
...
http {
server {
listen 8000;
server_name 127.0.0.1;
location /mysubpath {
proxy_pass http://unix:/run/gunicorn/socket;
}
}
}
...
Usually, we do proxy_pass http://someip:someport/; but in my case, it might require a different approach. Can someone please help.

NGINX default page is being shown instead of Flask app

I have displayed my NGINX configuration below. One of my Flask applications work (the one above), however the one below does not. The weird thing is, they were both working the other day, now the one below (example2) just returns the NGINX default page.
File structure:
/Signup/
/static/
/assets/
/bootstrap/
/css/
/fonts/
/img/
/js/
/templates/
register.html
main.py
NGINX Config:
server {
listen 80;
listen [::]:80;
server_name example1.domain.net;
location / {
proxy_pass http://127.0.0.1:5000;
}
}
server {
listen 80;
listen [::]:80;
server_name example2.domain.net;
location ^~ /static/ {
proxy_pass http://127.0.0.1:6000;
include /etc/nginx/mime.types;
root /root/Signup/;
}
}
Example 1 works as it should, example2 (second server block does not).
Edit: Thought I should note, I have no prior experience with NGINX, please don't assume.

Hosting 2 django project inside one VPS server

I am trying to run 2 django project in one single VPS server in 2 different domain. I am using gunicorn as my project server.
I have created 2 virtual env, 2 supervisor and 2 separate file in sites-available and enable-folder.
My project is running well but the problem is in one time only one project is running in both the domain. Though in my nginx sites-avaible files are given different domain as server_name still one django project is running both of the domain
Can any oone help.

Your two ngnix config files contains the same "sample_project_server" upstream name. Try to set a different upsteam name for each of your files.

Django application with nginx and gunicorn only showing welcome page rest all pages showing 404 error

I tried to deploy a sample django application in amazon ec2 server with the help of nginx and gunicorn. I added proxy pass in nginx. After I run the server and accessing my IP I was able to view the welcome to django page. But when I navigate to some other urls, say admin its shows 404 not found error.
How to fix this error.
Nginx config:
upstream app {
server 127.0.0.1:8000;
}
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www/html;
server_name IP;
location /static/ {
root /home/ubuntu/workspace/business;
}
location / {
proxy_pass http://app;
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
}
You need change this:
location / {
proxy_pass http://app;
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
For this:
location / {
proxy_pass http://gunicorn:8888; #use your gunicorn port
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
The problem was with the line
try_files $uri $uri/ =404;
This line is causing every url except the main url to route to 404 page.
I removed it and hence working.
Thanks to #Richard Smith for mentioning it in the comment

nginx intercepting google oauth redirect

I have my django app setup on a gunicorn server that is being proxied by nginx(also used for static files), and nginx is "intercepting" the GET request with the credentials code from Google! Why is nginx stealing the request instead of passing it to gunicorn to be processed?
here is my api info for my web application:
Client ID:
67490467925-v76j4e7bcdrps3ve37q41bnrtjm3jclj.apps.googleusercontent.com
Email address:
67490467925-v76j4e7bcdrps3ve37q41bnrtjm3jclj#developer.gserviceaccount.com
Client secret:
XquTw495rlwsHOodhWk
Redirect URIs: http://www.quickerhub.com
JavaScript origins: https://www.quickerhub.com
and here is the perfect GET request being stolen by nginx:
http://www.quickerhub.com/?code=4/bzqKIpj3UA3bBiyJfQzi3svzPBLZ.QoB_rXWZ6hUbmmS0T3UFEsPMOFF4fwI
and of course sweet nginx is giving me the "Welcome to nginx!" page...
Is there a way to tell nginx to pass these requests on to gunicorn? Or am I doing something incorrectly?
Thanks!

you have
server_name quickerhub.com;
the get request is coming back to
http://www.quickerhub.com/?code=4/bzqKIpj3UA3bBiyJfQzi3svzPBLZ.QoB_rXWZ6hUbmmS0T3UFEsPMOFF4fwI
quickerhub.com != www.quickerhub.com and so nginx is falling through to serving the default page (for when it can't find a vhost).
all you need to do is use
server_name www.quickerhub.com quickerhub.com;
or even better, add this to "canonicalise" all your urls to the version without www.
server {
server_name www.quickerhub.com;
expires epoch;
add_header Cache-Control "no-cache, public, must-revalidate, proxy-revalidate";
rewrite ^ http://quickerhub.com$request_uri permanent;
}
