nope, wrong one
You are missing the schema for Icinga Web 2
Table ‘icingaweb.icingaweb_user’ doesn’t exist
----------- ^^^^^^^^^^
This is a separate database only for the web interface
Go from here again: CentOS - Icinga Web
You most likely will have to enable the setup module again with icingacli module enable setup
The web setup will guide you through the process. When configuring the database for Icinga Web 2 make sure to input the correct database connection settings. If the setup then can’t import the schema with the data supplied it will ask for a privileged user (e.g. root)
Some time back I posted an overview of the communication of Icinga and its components. It might help you understand a bit better
