Mysql-u root-p

2. Create a database and authorize

CREATE DATABASE Nova; GRANT all privileges on Nova.* To'Nova'@'localhost'identified by'Nova_dbpass'; GRANT all privileges on Nova.* To'Nova'@'%'identified by'Nova_dbpass';

Replace NOVA_DBPASS with a suitable password.

Source the admin credentials to gain access to admin-only CLI commands:

SOURCE ADMIN-OPENRC. SH

3.To Create the service credentials, complete these steps:

Create the nova User:

OpenStack User Create--password-prompt Nova

ADD the admin role to the nova User:

OpenStack role Add--project service--user Nova Admin

Create the nova service entity:

OpenStack Service Create-   name Nova"OpenStack Compute" Compute

4.Create the Compute service API endpoint:

OpenStack Endpoint Create    --publicurl http://controller:8774/v2/%\ (tenant_id\) s \  --internalurl http://  Controller:8774/v2/%\ (tenant_id\) s \  --adminurl http://controller:8774/v2/%\ (tenant_id\) s \   --RegionRegionone   Compute
