    raise RuntimeError(
RuntimeError: ckan.site_url is not configured and it must have a value. Please amend your .ini file.

Focusing on the ckan.site_url issue, let's hit that first. The location of this file is

/etc/ckan/default/ckan.ini

To edit this file using vim

sudo vim /etc/ckan/default/ckan.ini

Find the site_url and update accordingly. Once completed, you will need to provide the location to the configuration file.

Initialize the CKAN database

sudo ckan db init

OR

sudo ckan -c /etc/ckan/default/ckan.ini db init

However, this command had the following response

sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) FATAL:  password authentication failed for user "ckan_default"
FATAL:  password authentication failed for user "ckan_default"

ckan_default is the default user in PostgreSQL

This issue is due to the password for this user not being set in the sqlalchemy.url setting in the ckan.ini file.

## Database Settings
sqlalchemy.url = postgresql://ckan_default:{pass}@localhost/ckan_default

Make sure you have replaced {pass} with the password you have used.

Running the init command again

ckan -c /etc/ckan/default/ckan.ini db init

Response:

2022-07-19 04:36:28,561 INFO  [ckan.cli.db] Initialize the Database
2022-07-19 04:36:31,104 INFO  [ckan.model] CKAN database version upgraded: base -> ccd38ad5fced (head)
2022-07-19 04:36:31,105 INFO  [ckan.model] Database initialised
Initialising DB: SUCCESS

Now is a good time to retest the supervisor status

sudo supervisorctl status

Response

ckan-datapusher:ckan-datapusher-00   RUNNING   pid 4846, uptime 0:46:00
ckan-uwsgi:ckan-uwsgi-00             RUNNING   pid 4847, uptime 0:46:00
ckan-worker:ckan-worker-00           RUNNING   pid 7844, uptime 0:15:06

Back on track and working

Reload the Supervisor daemon so the new processes are picked up:

sudo supervisorctl reload

After a few seconds run the following command to check the status of the processes:

sudo supervisorctl status

Like above, you will hopefully see three processes running without errors:

ckan-datapusher:ckan-datapusher-00   RUNNING   pid 25124, uptime 0:03:18
ckan-uwsgi:ckan-uwsgi-00             RUNNING   pid 25125, uptime 0:03:18
ckan-worker:ckan-worker-00           RUNNING   pid 25126, uptime 0:03:18

If some of the processes report an error, ensure you’ve run all the previous steps and check the logs located in /var/log/ckan for more details.
