Stage Three: Deploying your App

This is where the Django CMS comes in. This part is done on behalf of subscription system user connected via SSH. You must create the Subscription under Service Plan, and don’t forget to navigate to the domain’s Document Root, by default:

cd ~/httpdocs/

You also need to move existing files to the backup directory in the subscription, so they won’t be processed instead of the application:

mkdir ~/backup
$mv ~/httpdocs/* ~/backup/

Then, you can make the virtual environment for your App with the below command:

python36 -m virtualenv -p python36 python-app-venv

Great, now let’s enter it and make a couple of final adjustments before creating the App itself. Enter the virtual environment, install Django framework and check if it can be imported

source ./python-app-venv/bin/activate

pip install Django
python -c "import django;print(django.get_version())" 
2.0.3

The final step here is to create a passenger startup file passenger_wsgi.py inside of the “django-app” environment in order to serve our application via the application server. So, we’ll use the following:

import sys, os
ApplicationDirectory = 'djangoProject' 
ApplicationName = 'djangoProject' 
VirtualEnvDirectory = 'python-app-venv' 
VirtualEnv = os.path.join(os.getcwd(), VirtualEnvDirectory, 'bin', 'python') 
if sys.executable != VirtualEnv: os.execl(VirtualEnv, VirtualEnv, *sys.argv) 
sys.path.insert(0, os.path.join(os.getcwd(), ApplicationDirectory)) 
sys.path.insert(0, os.path.join(os.getcwd(), ApplicationDirectory, ApplicationName)) 
sys.path.insert(0, os.path.join(os.getcwd(), VirtualEnvDirectory, 'bin')) 
os.chdir(os.path.join(os.getcwd(), ApplicationDirectory)) 
os.environ.setdefault('DJANGO_SETTINGS_MODULE', ApplicationName + '.settings') 
from django.core.wsgi import get_wsgi_application 
application = get_wsgi_application()

Note that you should replace the variable values in lines 2 and 3 with your own variable values. Done? Now save the text file and get ready to deploy the app itself. As a sample, we’re going to use the “scaffold” app.

Create Django project:

django-admin startproject djangoProject

Allow serving requests from any host:

sed -i "s/ALLOWED_HOSTS = \[\]/ALLOWED_HOSTS = ['*']/" djangoProject/djangoProject/settings.py

Create a tmp directory for application caches:

mkdir tmp

Restart Application:
touch tmp/restart.txt

Now all you need to do is to change Domain Document Root, and if everything is OK, you’ll see your application as below.
