Back ground:
I bought a web hosting plan and created (by WordPress) a website. Now I want to create a new website on that server by python/flask but not WordPress because the standardized functions do not meet my requirements.
Problem description:
For testing purpose, I did not edit any Conf files or WSGI settings, just executed "python init.py" to start the new python web applications, in the backend, it showed app is running at http://:localhost:5000. But in the frontend, the web browser ended up waiting for response.
My web hosting provider had a look and they said Flask is not allowed for some security reasons.
My question:
I need to bind URLs to proper pages without using flask framework. Any suggestions and recommendations are welcome. Thank you very much for your help.

I knew that for deploying a Django application we have to use a combination of uWSGI + Nginx or Nginx + Gunicorn server. Is that necessary? I have a small doubt here. Can we deploy the entire application only in Nginx or only in Gunicorn? Will, it not work? Just for an example(leaving production) can't I do that?
For a full pledge application you need both web server and app server. Web server such as nginx or apache deliver static content but app server delivers dynamic content. Major differences between a web server and app server are:
A web server accepts and fulfills requests from clients for static content (i.e., HTML pages, files, images, and videos) from a website. Web servers handle HTTP requests and responses only.
An application server exposes business logic to the clients, which generates dynamic content. It is a software framework that transforms data to provide the specialized functionality offered by a business, service, or application. Application servers enhance the interactive parts of a website that can appear differently depending on the context of the request.

YES , you can. NO, you shouldn't.
If you run your app (in my case Django), on its development server. You can access it from a remote computer at its ip_address:port_number which should look something like 123.142.524.110:8000 and you can see your app at work.
You can also run Django with only gunicorn, it will still lack the web servers capabilities like sering static files efficiently or handling slow clients or DDOS handling. But it will run and that is all I can promise.
Unsure of whether Nginx can be directly tried with DJANGO app server, but I don't see why not. <<Probably someone else can attest to having successfully 'tried' it>>
I should repeat again, just coz its possible doesn't mean you should do it.
I created a basic Flask application with some built-in RESTFUL API capabilities. I basically followed this guide: Flask-Api-Guide. I managed to place the application in a docker container - some struggling was involved, refer to my other questions - my profile. I am now running Nginx as my "webserver"/"reverse proxy server" with Gunicorn, Flask and Python 3 in docker containers.
Everything starts up successfully, but when navigating to the relevant web page I get this message (below), instead of the expected swagger UI.
No API definition provided.
I have read posts suggesting this could be due to Nginx, and https. I would like to know how to configure Nginx and/or my Flask application to be able to view the Swagger UI.
Basically I need help on the best practice or "proper" method of prod deployment for a Swagger UI for this API server. If anyone could be of assistance in this regard it would be awesome.
I have attempted modifications to the Nginx conf file in hopes of finding a quick fix to the issue without any success.
I am a Trainee in a company learning Python. The company wants me to study Python and Google App Engine. I studied them both individually and even used Google App Engine to create Web application with Bootstrap and JavaScript.
However, I do not know how to use Python in Google App Engine. When or where I should used Python in Google App Engine? What is the role of Python in making a Web Application?
Python will act as a middleware between the front-end and the database usually serving as a Web Server (whose job is to handle requests) and an Application Server (whose job is to do the business logic and optionally add a security layer).
browser -> web-server(python?) -> app-server(python?) -> database -> browser
In small projects like a Flask App, Web Server and Application Server are the same. But this can run into scalability problems.
You said you already created a web application, how did you access it in the browser?
Instead of worrying about terminologies just try out some Hello World examples and things will be clear.
I am new to Flask Web with Python. I developed a simple Flask with Pycharm. Now I want to deploy it on my college server. I remember when I develop php web app I used to copy it to www folder in var and run it from there.
Can someone explain me how do I deploy python web app in Linux production server.
First, you need to figure out what your server provides from its sysadmin. There are tens of ways to do this, and all of them have different answers.
Given that you have used php on the system before, I'll assume you are using Apache httpd.
First, you would need to have a wsgi provider installed (e.g. mod_wsgi) , and then wire your application into the wsgi provider.
See the mod_wsgi page and flask docs for more information on how to precisely do this.
https://code.google.com/p/modwsgi/
http://flask.pocoo.org/docs/0.10/deploying/
Another option is to have python bring its own webserver and optionally have a proxy redirect / load balance.
I have a web server running Apache, and I need to implement a RESTful API on the same domain, and I'd like to use Django Restful Framework to serve the REST calls.
For example: going to http://myawesomedomain.com/ in a browser serves a good old fashioned web page delivered by Apache, but I need requests to http://myawesomedomain.com/api/customers/... to be handled by my Django Restful application.
Can someone please point me in the right direction. Is there an apache mod I need to activate to get it to serve Python? Do I have to redirect those requests to another service on the server?
Not looking for a comprehensive tutorial. I just don't know where to start.
Thanks in advance
I did some more digging and found the answer myself.
You use mod_wsgi.
Here is a perfect tutorial to get started: https://docs.djangoproject.com/en/1.7/howto/deployment/wsgi/modwsgi/
