How to start Django server that is located in another machine - django

For business matters i've moved my local server to enterprise's server for doing some tests but i don't know how to start/stop server via local, i guess it's launching via python runserver... but i don't know how to do it with the files allocated in another machine.
Regards!

You should connect to a remote machine, activate virtualenv , python manage.py runserver serverip:port . That's all. Also check that your port is not closed by firewall.

How to run a Django's application server on a VPS server

I have an application that should run via VPS terminal-based so that the web app can be online permanently.
The command: python manage.py runserver 173.249.8.237:8000 should be executed via the VPS terminal because when I use putty via my laptop, whenever I switch off my putty software via my laptop, the application won't be accessible.
Please, suggest to me a way open a terminal in order to run the Django application server.
Or, is there any method that can allow me to my Django web application on VPS?
Thanks in advence
Don't do that.
runserver according Django Docs
DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone
through security audits or performance tests. (And that’s how it’s
gonna stay. We’re in the business of making web frameworks, not web
servers, so improving this server to be able to handle a production
environment is outside the scope of Django.)
You need to configure your Django application to run in production environments. You change choose docker for that.
Or simple running with gunicorn.
Access your VPS through SSH or Putty.
Copy your application code inside VPS
Configure your application to run with gunicorn or docker
Access your VPS address in your browser.
And turn of the DEBUG mode, by setting DEBUG=False

How to access Django app in docker container from another machine?

I am pretty new to Docker and Django. So what i did was, putty to a linux server and created a folder in the root directory and then using django-admin startproject I started a new project.
Now, since I am using putty for ssh terminal access, I will not be able to access a browser in the linux machine and then ping 127.0.0.1:8000 to see whether "congratulations!" screen by Django is visible or not.
So I assumed that the server might be running after runserver command. Then using docker I prepared a container in the linux machine where I have exposed port 9000. Also I cannot access this container since I cannot access the browser in the linux machine. Now, I have three questions below:
1.) How to access this docker container (inside the linux machine) using my windows machine? By this I mean, if I open up lets say google chrome browser in the windows machine, and enter some url:port, will I be able to see the "congratulations!" screen on my browser on windows?
2.) I am pretty confused with how this container network port and ip works (I mean how does host or any other pc access this docker container) I tried looking up on many documentation and youtube videos but I am very much confused. Because I know to make your website/app accessible to the external world we need domain name hosted on some cloud for which we need to pay, but how can docker do this for free? Might sound like a lame one, but please help me understand.
3.) How should my docker run command look like for accessing from my windows machine?
My dockerfile:
FROM python:3.6-slim
ENV PYTHONUNBUFFERED=1
RUN mkdir /Django
WORKDIR /Django
ADD . /Django
RUN pip install -r requirements.txt
EXPOSE 9000
CMD python manage.py runserver 0.0.0.0:9000
I am using the following command to build:
docker build -t myproj .
Please help clarifying my questions guy. I'll be forever grateful :)
Thanks all!
When you run the container, you need a docker run -p option:
docker run -p 12345:9000 myproj
The second port number must match the port number the actual server process is listening on (in your case, the port argument to ./manage.py runserver). The first port number can be any port number that's not otherwise in use on the host system.
Then (up to networking and firewall constraints) another system can reach the container by using the host's IP address and the first port number; http://my-dev-system.internal.example.com:12345. If you're calling from the host directly then these two systems are the same and in this special case you can use http://localhost:12345.
As an implementation detail the container happens to have its own IP address but you never need to look it up or use it. (Among other problems, it is not accessible from other machines.) From other systems' points of view a Docker-based process is indistinguishable from the process running directly on the host. Docker doesn't address the problems of needing somewhere to host the application, coming up with a DNS name for the host, or other similar concerns.
Try running it without EXPOSE 9000, when you are exposing port it's visible only inside of a container and not to the outer world. After doing so, go to a browser and navigate to <server_ip>:9000 and you will probably see the message.

cannot access a development server on a server im ssh'd into

I am deploying a django app from a Centos server. When i do a python3.6 manage.py runserver 8000 command it starts a development server no problem. I am not able to access this page from my local computer to test it.
so the steps i take are: i ssh into the server by doing ssh <user>#url.com and then run the dev server with the above command. I then go to the browser on my laptop and type url.com:8000 and will come up with Unable to connect
I also have this problem when running my apache server for production. i would have no problems putting up the server on the server im ssh'd into but cannot access the webpage.
I know this is very little information to go on but does this sound like a server side issue at url.com? Should i be contacting the administrators with this, or is this something on my end possibly?
Maybe i need to configure the address my settings.py in my django app?
You probably want to run it so it listens on any interface. From the documentation:
Note that the default IP address, 127.0.0.1, is not accessible from
other machines on your network. To make your development server
viewable to other machines on the network, use its own IP address
(e.g. 192.168.2.1) or 0.0.0.0 or :: (with IPv6 enabled).
By example, you should start the server with
python3.6 manage.py runserver 0.0.0.0:8000
In general, it is probably not wise to keep such a thing running on the web, particularly with debug on. From the same documentation link:
DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone
through security audits or performance tests. (And that’s how it’s
gonna stay. We’re in the business of making Web frameworks, not Web
servers, so improving this server to be able to handle a production

How can I setup my Django server on LAN

I have made a Django employee portal which will be accessed by LAN only.
It works when another employee opens it by typing the IP address of the server on their web browser.
However I don't have much experience with Django and I think that this is not the proper way to do so. I run my server using python manage.py runserver and use sqlite3 as database.
Is this the correct way to do so? How should I deploy my portal.
I am very new to Django and would appreciate some help.
I am using a windows machine and I used pycharm to make my project.
And also I need to know how can I have the server running even when I close pycharm, as ctrl-C or closing pycharm breaks the server
The simplest way to allow everyone on your network to access your Django webserver is to do python manage.py runserver 0.0.0.0:8000
This allows anyone on the network to access it by using your IP address (or computer name) and the port 8000. (so something like 192.168.1.2:8000)
This of course isn't really nice specially if you intent to use this as a production environment. panchicore's answer should help you setup a good production environment.
Setting up Django and your web server with uWSGI and nginx
There is not an official way to do it, what I do effectively, intranet solutions as well, is with nginx and uWSGI (on ubuntu).
Serving with Windows? perhaps: https://www.toptal.com/django/installing-django-on-iis-a-step-by-step-tutorial is a proper way to do so.
I think for ip address issue you can use host names
https://wesbos.com/localhost-mobile-device-testing/
and for running server in background you can use gunicorn with supervisor check this out https://www.agiliq.com/blog/2014/05/supervisor-with-django-and-gunicorn/

How to configure Elastic IP with django app in aws?

I am building an app using django in EC2-ubuntu and i have associated Elastic ip with my instance.
i have done following steps :
1. first created instance of ubuntu in ec2 free tier.
2. installed python.
3. installed pip.
4. installed django.
5. create a django project using django-admin startproject.
6. run server using these commads python manage.py runserver 0.0.0.0:80
7. created an elastic ip and associated to the instance.
8. configure security inbound settings with http 0.0.0.0:80 address.
9. able to ping my project using any browser.
But the problem is when i am closing my putty session where i supplied runserver command, django project is also stopped. i did not stop it manually.
Please, help me to keep on running after closing putty session as well.
Thanks,
Kripa Sharma
Take a look at this Answer
I highly recommend that you start using Elastic Beanstalk (Python instance) to take care of all these steps for you. Very simple to setup, and no need to worry about any of the steps you listed.
You can use this instruction to see how you can deploy a Django app in less than 5 minutes.
The problem
You are trying to persist the debug server for a remotely deployed application.
You probably need to review the runserver command documentation. Here are the relevant parts:
django-admin runserver [addrport]
Starts a lightweight development Web server on the local machine. By default, the server runs on port 8000 on the IP address 127.0.0.1. You can pass in an IP address and port number explicitly.

DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that’s how it’s gonna stay. We’re in the business of making Web frameworks, not Web servers, so improving this server to be able to handle a production environment is outside the scope of Django.)
A webserver
Having skimmed the above docs, you may want to look at "How to deploy with WSGI" section, which gives a few recommendations for commonly used Web servers. My favorite, Gunicorn, includes a usage example:
$ pip install gunicorn
$ gunicorn myproject.wsgi
Having decided, and installed a webserver, you'd need to "daemonize" it and expose it to the world.
The former is usually done by creating a service on your OS, for ubuntu it would be either upstart or systemd depending on the version. Gunicorn docs have examples for both.
The latter is usually achieved with an http-server/proxy such as nginx or apache httpd. And again, Gunicorn has an example for us.
You can see why I like it so much ☺️
Epilogue
While technically possible to run the debug server as a service or even in a terminal multiplexer such as GNU screen or tmux, it's not a recommended or stable long term solution.
That said, these are very useful to know about, so read on the above tools and learn to use them, since they would be invaluable to have in your toolset in the future, for example to avoid accidentally terminating a long running command (such as migration), etc.
