At this point, we can confirm whether our Odoo instance is up and responding to requests as expected.

If Odoo is running properly, we should be able to get a response from it and see no errors in the log file. We can check whether Odoo is responding to HTTP requests inside the server by using the following command:

$ curl http://localhost:8069
<html><head><script>window.location = '/web' +  location.hash;</script></head></html>

In addition, to see what is in the log file, use the following command:

$ sudo less /var/log/odoo/odoo-server.log

You can also follow what is being added to the log file live, using tail -f as follows:

$ sudo tail -f /var/log/odoo/odoo-server.log
