I generally deploy django web applications in Ubuntu.
But currently we are using cpanel(not looking for alternatives) which doesnt work in Ubuntu. so want to know if moving to centos for cpanel is worth ?
Because my fear is, if we move to centos server, do we have to face some complex issues(with django deployment) that we might take lot of time(we are good at Ubuntu).
Deploying on centos is essentialy the same. You will probably want to run django in gunicorn and supervisor watching over the process. And nginx for serving static files.
I have done deployment on CentOS aswell as on Ubuntu and I didn't encounter any problems.
You can use the below link to help you in deployment
https://www.digitalocean.com/community/tutorials/how-to-redirect-www-to-non-www-with-nginx-on-centos-7
and if you had any issues in permission you can disable SE-LINUX

I created a website that uses vuejs as the frontend and django as the backend with another service running behind everything that im making api calls to.
So django is setup in a way to look at the dist folder of Vuejs and serve it if you run manage.py runserver. but the problem is that my service that I created is
is also in python and it needs to run in a virtualenv in order to work (It uses tensorflow 1.15.2 and this can only run in a contained environment)
I'm sitting here and wondering how I can deploy the django application and keep the virtualenv active and Im coming up with nothing, I've tried doing some research on this but everything I found was not relevant to my problem. I've deployed it and when I close the ssh connection the virtualenv stops.
If there is anyone that can enlighten my ways I would appreciate it.
i think you need to nginx: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04
if you are search for keep states just in terminal i suggest tmux https://github.com/tmux/tmux/wiki
You can use uWSGI and nginx to deploy Django apps on server. Here's helpful articles:

Django official docs also has a page about it: https://docs.djangoproject.com/en/3.1/howto/deployment/wsgi/uwsgi/
There are articles from developers so you can refer them in case you get stuck anywhere:

Hi am developing my first web application and i have used django for the same. Now, after completing developing the site i want to host the same on a web server. I do have high speed static ip internet and dedicated server available for the same.
I want to use nginx and gunicorn for the purpose of server applications, i have thoroughly googled the topic and gone through at least 20 tutorials for deploying django applications, but almost all them have explained the process with older versions of django.
I have used django 1.8, it would be of great help if someone could provide a source to refer to continue with the deployment of the site.
Thanks in advance
The version of Django does not matter, i suggest you follow the next tutorial Deployment Django nginx supervisor
I have a django application running on a server. I want to use let's encrypt to provide an encrypted connection. I could use the standalone option of their ACME client, but i don't want to stop my server, what i would have to do.
So there is the webroot option, that work with my allready running webserver (nginx). Django would process the request in this case. My question is, how should it look like on the django side to get this running (keeping automated renewal several months in mind)?
I don't know what setup others use, but I generally set up Django apps with Nginx serving static content and Gunicorn as the application server. It's widely accepted that Django apps usually use this kind of two web server setup. The standard instructions for setting up Let's Encrypt with Nginx worked fine for me.
Or Digital Ocean have an excellent guide too.
EDIT: It looks like Nginx can do a "graceful" reload that just updates the config with no downtime. For Debian or Ubuntu pre Systemd this would be sudo service nginx reload, while for a distro with Systemd the command is sudo systemctl reload nginx.service.
In case other users come this way like I did from Google, here's how I improved this situation:
I was unsatisfied by my options when it came to creating ACME challenges for Let's Encrypt when running a Django application. So, I rolled my own solution and created a Django app! Basically, you can manage your ACME challenges as just another object, and the app will produce the proper end-point URL.
Yes you are installing an app which means a deploy / update to your app, but once you've done that managing your challenges is far easier in the long run.
Simply pip install django-letsencrypt and follow the README to be on your way.
I am quite computer-illiterate, but I have managed to utilize the Django framework on my own machine. I have had an account on Amazon Web Service (AWS) for some time, but it appeared rather complex to set-up and to make use of, so I put it of for a while. Then I decided to give it a try, and it was not so hard as I first thought to load a AMI and connect to the server with PuTTY. But since I were already using BitNami's Django-Stack, I decided to take a look at their hosting offer (which builds on AWS). Since they appeared to offer "one-click deployment", I set up a new server through their interface. But then, it seems like the "one-click deployment"-promise is with regard to the server itself. There does not seem to be any interface for deploying Django projects through their site. Having used PuTTY already, and adding WinSCP to my machine, I can acceess the server and load my Django-code unto the server. But then I am lost. The documentation seems a bit thin (look here).
The crux of this is the following: Can anyone make this part of the process more understandable. I.e., how to deploy a Django project on a Linux server with Apache/mod_WSGI?
The other question is: I want to use Postgres. Am I free to install this on the server. Should I opt for EBM (EMB?) for this, or what is the downside of not having EBM?
I hope I am not too unworthy of your attention, thanks!
how to deploy a Django project on a Linux server with Apache/mod_WSGI The Bitnami AMI already comes with all this configured. Once installed try going to the EC2 public url on the default 8000 port and you will see the demo django project setup there. You can add your own project once you have logged into the machine via putty check the /home/bitnami/ directory for the demo project. Copy your project, configure your database The other question is: I want to use Postgres. Am I free to install this on the server Postgres and Mysql are already installed the same way you would do on your local machine. The in your project do ./manage.py runserver 0.0.0.0:9000 since the 8000 port is already running another application.
I am quite a noob when it comes to deploying a Django project. I'd like to know what are the various methods to deploy Django project and which one is the most preferred.
The Django documentation lists Apache/mod_wsgi, Apache/mod_python and FastCGI etc.
mod_python is deprecated now, one should use mod_wsgi instead.
Django with mod_wsgi is easy to setup, but:
you can only use one python version at a time [edit: you even can only use the python version mod_wsgi was compiled for]
[edit: seems if I'm wrong on mod_wsgi not supporting virtualenv: it does]
So for multiple sites (targeting different django/python versions) on a server mod_wsgi is not
the best solution.
FastCGI can be used with virtualenv, also with different python versions, as you run it with
./manage.py runfcgi …
and then configure your webserver to use this fcgi interface.
The new, hot stuff about django deployment seems to be gunicorn. It's a webserver that implements wsgi and is typically used as backend with a "big" webserver as proxy.
Deployment with gunicorn feels a lot like fcgi: you run a process doing the django processing stuff with manage.py, and a webserver as frontend to the world.
But gunicorn deployment has some advantages over fcgi:
speed - I didn't find the sources, but benchmarks say fcgi is not as fast as the f suggests
config files, for fcgi you must do all configuration on the commandline when executing the manage.py command. This comes unhandy when running multiple django instances via an init.d (unix-like OS' system service startup). It's always the same cmdline, with just different configuration files
gunicorn can drop privileges: no need to do this in your init.d script, and it's easy to switch to one user per django instance
gunicorn behaves more like a daemon: writing pidfile and logfile, forking to the background etc. makes again using it in an init.d script easier.
Thus, I would suggest to use the gunicorn solution, unless you have a single site on a single server with low traffic, than you could use the wsgi solution. But I think in the long run you're more happy with gunicorn.
If you have a django only webserver, I would suggest to use nginx as frontendproxy, as it's the best performing (again this is based on benchmarks I read in some blogposts - don't have the url anymore).
Personally I use apache as frontendproxy, as I need it for other sites hosted on the server.
A simple setup instruction for django deployment could be found here:
http://ericholscher.com/blog/2010/aug/16/lessons-learned-dash-easy-django-deployment/
My init.d script for gunicorn is located at github:
https://gist.github.com/753053
Unfortunately I did not yet blog about it, but an experienced sysadmin should be able to do the required setup.
Use the Nginx/Apache/mod-wsgi and you can't go wrong.
If you prefer a simple alternative, just use Apache.
There is a very good deployment document: http://lethain.com/entry/2009/feb/13/the-django-and-ubuntu-intrepid-almanac/
I myself have faced a lot of problems in deploying Django Projects and automating the deployment process. Apache and mod_wsgi were like curse for Django Deployment. There are several tools like Nginx, Gunicorn, SupervisorD and Fabric which are trending for Django deployment. At first I used/configured them individually without Deployment automation which took a lot of time(I had to maintain testing as well as production servers for my client and had to update them as soon as a new feature was tested and approved.) but then I stumbled upon django-fagungis, which totally automates my Django Deployment from cloning my project from bitbucket to deploying on my remote server (it uses Nginx, Gunicorn, SupervisorD, Fabtic and virtualenv and also installs all the dependencies on the fly), all with just three commands :) You can find more about it in my blog post here. Now I even don't have to get involved in this process(which used to take a lot of my time) and one of my junior developers runs those three commands of django-fagungis mentioned here on his local machine and we get a crisp new copy of our project deployed in minutes without any hassle:)
