# Cloud Django_2
[](https://snyk.io/test/github/mramshaw/Cloud_Django_2?style=plastic&targetFile=requirements.txt)
This project follows on from my [Writing_Django_2](https://github.com/mramshaw/Writing_Django_2) project, which is a simple Hello World in Django 2 LTS.
[As might be expected, there were breaking changes between Django and Django 2. So rather than upgrade my
[Cloud_Django](https://github.com/mramshaw/Cloud_Django) repo, it seemed to be a better idea to create
the __polls__ app in Django 2 and proceed from there, this time with Django 2 LTS.]
It will use [gunicorn](http://gunicorn.org/) which is a web server for [Django](https://docs.djangoproject.com/en/2.2/howto/deployment/wsgi/gunicorn/).
Specifically, it is a [WSGI](https://en.wikipedia.org/wiki/Web_Server_Gateway_Interface) server.
The plan of attack is as follows:
* [Install and test 'gunicorn'](#gunicorn)
* [Configure 'gunicorn'](#configure-gunicorn)
## gunicorn
To install locally:
$ pip3 install --user gunicorn
Or simply use the `requirements.txt` file:
$ pip3 install --user -r requirements.txt
Verify the version:
```bash
$ gunicorn --version
gunicorn (version 20.0.2)
$
```
Lets see if it runs (this needs to be in the same folder as `manage.py`):
```bash
$ cd polls
$ gunicorn polls.wsgi

$
```
## Configure gunicorn
Now we need to open up `gunicorn` with a `gunicorn.conf.py` file (for some reason,
this config file needs to be tagged as a Python file). By default, `gunicorn` runs
locally and will only accept local connections. We will configure it to run in
__promiscuous mode__ (which is a terrible practice, we should really run it behind
a front-end [__nginx__ is recommended], but we can fix this later).
We will create this file as follows:
```python3
import multiprocessing
bind = "0.0.0.0:8000"
workers = multiprocessing.cpu_count() * 2 - 1
```
Once more, with our config file:
```bash
$ gunicorn -c gunicorn.conf.py polls.wsgi

Okay, everything runs.
