Nova Computer - En el nodo controlador

Creamos las bases de datos necesarias para "nova" y otorgamos los permisos necesarios.

      root@nova-controller:~# mysql -u root -p
      MariaDB [(none)]> CREATE DATABASE nova_api;
      MariaDB [(none)]> CREATE DATABASE nova;
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
      MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

Cargamos las credenciales del usuario Admin.

      root@client:~$ source admin-openrc

Creamos el usuario "nova", lo añadimos al rol "admin" y al projecto "service".

      root@client:~$ openstack user create --domain default --password-prompt nova
      root@client:~$ openstack role add --project service --user nova admin

Creamos la entidad de servicio para nova-computer.

      root@os-client:~$ openstack service create --name nova --description "OpenStack Compute" compute

Creamos los endpoints para la API de nova-compute.

      root@os-client:~$ openstack endpoint create --region RegionOne compute public http://NOVA_CONTROLLER_IP:8774/v2.1/%\(tenant_id\)s
      root@os-client:~$ openstack endpoint create --region RegionOne compute internal http://NOVA_CONTROLLER_IP:8774/v2.1/%\(tenant_id\)s
      root@os-client:~$ openstack endpoint create --region RegionOne compute admin http://NOVA_CONTROLLER_IP:8774/v2.1/%\(tenant_id\)s

Instalamos los paquetes necesarios en el nodo controlador, nova-controller.

      root@nova-controller:~# apt install -y nova-api nova-conductor nova-consoleauth nova-novncproxy nova-scheduler

Editamos en nova_controller el fichero de configuración /etc/nova/nova.conf.

Reiniciamos los servicios.

      root@nova-controller:~# service nova-api restart
      root@nova-controller:~# service nova-consoleauth restart
      root@nova-controller:~# service nova-scheduler restart
      root@nova-controller:~# service nova-conductor restart
