Server Setup

Prerequisites

To install on a server, we need:

  • uwsgi
  • nginx
  • letsencrypt/certbot
  • python 3
  • pip

If you're on Red Hat, this will involve installing developer tools so you can build uwsgi:

yum groupinstall "Development Tools"

Then install all the tools as:

apt install nginx python3 python3-devel python-certbot-nginx
pip3 install uwsgi

Installation

First, we need to collect the static files so uwsgi can see them. We do this by cding into the root and running collectstatic as:

cd prosthetics
python manage.py collectstatic

Nginx

We need to set up nginx to serve the page. Install nginx, link the config file provided to the custom/nginx/ directory. Assuming it's been installed for a user called rsg:

systemctl start nginx.service
sudo ln -s /home/rsg/prosthetics/custom/deploy/nginx/conf/prosthetics-prod.conf /etc/nginx/sites-available/.
sudo ln -s /home/rsg/prosthetics/custom/deploy/nginx/conf/prosthetics-prod.conf /etc/nginx/sites-enabled/.
systemctl restart nginx.service

Or, if you're on Red Hat, it's a lot less fun:

systemctl start nginx.service
sudo ln -s /home/rsg/prosthetics/custom/nginx/conf/prosthetics /etc/nginx/conf.d/prosthetics-prod.conf
systemctl restart nginx.service

UWSGI

Then we need uwsgi to serve the page for nginx. Modify uwsgi.ini to point at the correct location for the static files. If you have installed for a user named rsg, then you shouldn't need to edit anything. If you have modified it, you'll need to adjust the path to wherever collectstatic put them.

Launch a screen session then run uwsgi as:

screen
uwsgi --ini uwsgi.ini
[Ctrl-A, Ctrl-D]

SSL Certificate

We then need to set up the SSL certificate for the page using letsencrypt.

sudo certbot --nginx -d [your URL]

/etc/letsencrypt/live/prosthetics/fullchain.pem;
