I have a nextjs app and Django app running on a Linux server. For the purposes of SSR, I am trying to get data from the Django app to the nextjs app using getServerSideProps. The easiest I would do this is to send a request from the nextjs app to the Django app.
This was relatively easy for me to do in development. Requests would be sent to http://localhost:8000, since the Django app was using port 8000, from port 3000 which is the port the nextjs app is using.
However, in our production server, the Django app run on a Unix socket, served via gunicorn.
upstream app_server {
server unix:/path/to/gunicorn.sock fail_timeout=0;
}
How can I request for data from the Django app to the nextjs app when the Django app is accessible via Unix socket?

django website is working fine on localhost but when hosted on server using nginx and gunicorn, some APIs are throwing 500 server error. This problem is with some APIs and rest of the APIs are working well. Please help me what should I do?
Please, I need to configure Django Channels on redis-channel-layer on windows IIS in production. It is running very well in development.
I have installed redis, daphne. I have set the IIS as proxy server with URL Rewrite pointing the Inbound to localhost 6379 to redis-layer channels. I used python manage.py runworker. and also started the daphne server with the daphne command.
They all ran very well, but there is no websocket handshake for my url.
I am planing to deploy my Django application with HTTP/2 protocol but I'm unable to find the proper solution. How can I serve my Django web application with HTTP/2, the only thing that I find is hyper-h2.
I read the documentation but unable to setup the connections.
You can do with Nginx proxy
if you have existing nginx config. you do by just adding a word .http2 in listen
listen 443 ssl http2 default_server;

One option is to use Apache httpd server with mod_wsgi. Apache supports terminating HTTP/2. The link to your Django application is still via WSGI API so you don't really get any access to HTTP/2 specific features in your application. You can though configure Apache to do things like server push on your behalf.

https://httpd.apache.org/docs/2.4/mod/mod_http2.html
To support HTTP 2.0, You can deploy Django apps on web servers like Daphne using ASGI (which is the spiritual successor to WSGI).
you can read more about deploying Django with ASGI in the official documentaion

I want to create a Flask app with embedded bokeh server document deployed on a web server. Current bokeh documentation demonstrates how to do this by running Flask on Port 8080 and the bokeh server on Port 5006.
In order to deploy on a very locked-down web server, I want Flask and the bokeh server to share a port, i.e. both use Port 8080. Is that possible and if so what is required...
A lot of Django app deployments over Amazon's EC2 use HTTP servers NGINX and Gunicorn.
I was wondering what they actually do and why both are used in parallel. What is the purpose of running them both in parallel?
They aren't used in parallel. NGINX is a reverse proxy. It's first in line. It accepts incoming connections and decides where they should go next. It also (usually) serves static media such as CSS, JS and images. It can also do other things such as encryption via SSL, caching etc.
Gunicorn is the next layer and is an application server. NGINX sees that the incoming connection is for www.domain.com and knows (via configuration files) that it should pass that connection onto Gunicorn. Gunicorn is a WSGI server which is basically a:
simple and universal interface between web servers and web applications or frameworks
Gunicorn's job is to manage and run the Django instance(s) (similar to using django-admin runserver during development)
The contrast to this setup is to use Apache with the mod_wsgi module. In this situation, the application server is actually a part of Apache, running as a module.
Nginx and Gunicorn are not used in parrallel.
Gunicorn, is a Web Server Gateway Interface (WSGI) server
implementation that is commonly used to run Python web applications.
NGINX is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server.
Nginx responsible for serving static content, gzip compression, ssl,
proxy_buffers and other HTTP stuff.While gunicorn is a Python HTTP server that interfaces with both nginx and your actual python web-app code to serve dynamic content.
The following diagrams shows how nginx and Gunicorn interact.
