h2. How to use

# Configure your app

# Install python requirements into the pyvenv

# Restart uwsgi to restart your app

h2. Configure your app

h3. WSGI

* Ensure that there is _projectname_/wsgi.py in your project root

h3. Database

Add the following to your settings.py:

<pre>

DATABASES = {

    'default': {

        'ENGINE': 'django.db.backends.postgresql_psycopg2',

        'NAME': 'app',

    }

}

</pre>

h2. Deploy

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

<pre>

ssh app@MYHOSTNAME

</pre>

* 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

h2. Install python requirements into the pyvenv

Pyvenv has been installed and you need to use pyvenv found in *~/pyvenv*, as uwsgi loads this pyvenv before loading your app.

<pre>

. ~/pyvenv/bin/activate

pip install ...

</pre>

h2. Restarting the app

* *sudo systemctl restart uwsgi*

h3. 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*
