How to use¶

1. Configure your app
2. Deploy your app
3. Install python requirements into the pyvenv
4. Restart uwsgi to restart your app
5. Go to http://your-hostname/ and enjoy!

Configure your app¶

WSGI¶

• Ensure that there is projectname/wsgi.py in your project root

Database¶

Add the following to your settings.py:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'app',
    }
}

Static and media files¶

Static files should be place in /home/app/app/static and media files in /home/app/app/media.

Deploy¶

You can login to your VM as user app (for the django app) and root (in case you need to change settings):

ssh app@MYHOSTNAME

• Deploy / update your app into the folder ~app/app (that is the app folder in the home of the user app)
• We recommended to use git to deploy it

Install python requirements into the pyvenv¶

Pyvenv has been installed to ~app/pyvenv for you.
Required packages for the hosting like PostgreSQL support and uwsgi support have already been placed.

You need to use pyvenv found in ~app/pyvenv, as uwsgi loads this pyvenv before loading your app.

To install your requirements use:

. ~/pyvenv/bin/activate
pip install ...

Restarting the app¶

• sudo systemctl restart uwsgi

Viewing logfiles¶

• nginx access log: tail -F /var/log/nginx/access.log
• nginx error log: tail -F /var/log/nginx/error.log
• uwsgi log: tail -F /var/log/uwsgi/app/app.log

Description of the stack¶

Technologies¶

• Debian 8
• nginx
• PostgreSQL
• uwsgi

Configuration¶

• user "app"
  • in group "adm" (to view logfiles)
• PostgreSQL with
  • database "app"
  • Listens only on localhost / socket (no remote connections) **
