Introduction to Configuring GeoNode (Basics)

GeoNode is built on top of Django. As a Django application GeoNode follows the common rules of a Django project.

In particular every Django project must have a special python file called settings.py which will be used to set the global variables and behavior of the whole framework.

Some settings variables are mandatory for a Django project, as an instance the version, the site url, the allowed hosts, the database configuration, the debug mode, etc… For more information about the common Django settings you can check the official Django documentation.

GeoNode Settings

GeoNode, of course, has this file too which is located into the /opt/geonode/geonode/settings.py location.

• In order to inspect the contents of the GeoNode settings file, open a file system browser and open it with a text editor

  

There are plenty of variables listed on the settings file, most of them have a notation similar to the following one:

   SITEURL = os.getenv('SITEURL', _default_siteurl)

That means that GeoNode looks first for the variable value into the System Environment and, if no value or variable has been found, it falls back to a default one.

You can find a full list of available settings from the GeoNode official documentation here.

Exercise: Settings Update to Toggle User Registration

Changing some GeoNode settings can be done by:

1. Udate or add the corresponding ENV variable value (or add it if missing)
2. Restart the Django service

• Go to the folder /opt/geonode/ and enable the Python virtualenv by typing:

   workon geonode
  

• Edit the UWSGI file setting the system ENV by typing:

   sudo vim /etc/uwsgi/apps-enabled/geonode.ini
  

• Search for the line

   env = ACCOUNT_OPEN_SIGNUP=True
  

  and turn it to False

   env = ACCOUNT_OPEN_SIGNUP=False
  

  save and close by typing the sequence ESC :wq!

• Restart the UWSGI service by typing:

   touch geonode/wsgi.py
  

• Follow the GeoNode logs in order to be sure that everything is ok

   sudo tail -500f /var/log/uwsgi/app/geonode.log
  

• Once the service restarted successfully, refresh the GeoNode home page, sign out if logged in, and verify that the user registration is now disabled
