Add nginx config and update setup instruction

[kantegory]

I guess, it'll be UWSGI + NGINX for improving work of web-app.

It can helps: Bottle + UWSGI + Nginx Quickstart

NGINX + UWSGI

Install requirements:

epmi uwsgi uwsgi-plugin-python3 python3-bottle nginx

Then copy project dir to /var/www:

cp -r accreditation_system /var/www

UWSGI config

Let's create UWSGI config:

cd /etc/apps-available/ && nano accreditation.ini

And paste next lines:

[uwsgi]
socket = /run/uwsgi/app/accreditation/socket
chdir = /var/www/accreditation_system
master = true
plugins = python3
file = main.py
uid = www-data
gid = www-data

Then create a symlink:

ln -s /etc/uwsgi/apps-available/accreditation.ini /etc/uwsgi/apps-enabled/accreditation.ini

NGINX config

upstream _bottle {
    server unix:/run/uwsgi/app/accreditation/socket;
}

server {
    listen [::]:80;
    listen 80;
    server_name YourServerName;
    root /var/www/accreditation_system;

    location / {
        try_files $uri @uwsgi;
    }

    location @uwsgi {
        include uwsgi_params;
        uwsgi_pass _bottle;
    }
}
