Install and configure controller node for Ubuntu
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This section describes how to install and configure the Compute service,
|
|
code-named nova, on the controller node.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
Before you install and configure the Compute service, you must create
|
|
databases, service credentials, and API endpoints.
|
|
|
|
#. To create the databases, complete these steps:
|
|
|
|
* Use the database access client to connect to the database
|
|
server as the ``root`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
# mysql
|
|
|
|
* Create the ``nova_api``, ``nova``, and ``nova_cell0`` databases:
|
|
|
|
.. code-block:: console
|
|
|
|
MariaDB [(none)]> CREATE DATABASE nova_api;
|
|
MariaDB [(none)]> CREATE DATABASE nova;
|
|
MariaDB [(none)]> CREATE DATABASE nova_cell0;
|
|
|
|
* Grant proper access to the databases:
|
|
|
|
.. code-block:: console
|
|
|
|
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';
|
|
|
|
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \
|
|
IDENTIFIED BY 'NOVA_DBPASS';
|
|
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \
|
|
IDENTIFIED BY 'NOVA_DBPASS';
|
|
|
|
Replace ``NOVA_DBPASS`` with a suitable password.
|
|
|
|
* Exit the database access client.
|
|
|
|
#. Source the ``admin`` credentials to gain access to admin-only CLI commands:
|
|
|
|
.. code-block:: console
|
|
|
|
$ . admin-openrc
|
|
|
|
#. Create the Compute service credentials:
|
|
|
|
* Create the ``nova`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack user create --domain default --password-prompt nova
|
|
|
|
User Password:
|
|
Repeat User Password:
|

|
|
| name | nova |
|
|
| options | {} |
|
|
| password_expires_at | None |
|
|
+---------------------+----------------------------------+
|
|
|
|
* Add the ``admin`` role to the ``nova`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack role add --project service --user nova admin
|
|
|
|
.. note::
|
|
|
|
This command provides no output.
|
|
|
|
* Create the ``nova`` service entity:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack service create --name nova \
|
|
--description "OpenStack Compute" compute

|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack endpoint create --region RegionOne \
|

compute public http://controller:8774/v2.1

Install and configure components
|
|
--------------------------------
|
|
|
|
.. include:: shared/note_configuration_vary_by_distribution.rst
|
|
|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# apt install nova-api nova-conductor nova-consoleauth \
|
|
nova-novncproxy nova-scheduler nova-placement-api
|
|
|
|
#. Edit the ``/etc/nova/nova.conf`` file and complete the following actions:
|
|
|
|
* In the ``[api_database]`` and ``[database]`` sections, configure database
|
|
access:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[api_database]
|
|
# ...
|
|
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api
|
|
|
|
[database]
|
|
# ...
|
|
connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova
|
|
|
|
Replace ``NOVA_DBPASS`` with the password you chose for the Compute
|
|
databases.
|
|
|
|
* In the ``[DEFAULT]`` section, configure ``RabbitMQ`` message queue access:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
transport_url = rabbit://openstack:RABBIT_PASS@controller
|
|
|
|
Replace ``RABBIT_PASS`` with the password you chose for the ``openstack``
|
|
account in ``RabbitMQ``.
|
|
|
|
* In the ``[api]`` and ``[keystone_authtoken]`` sections, configure Identity
|
|
service access:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[api]
|
|
# ...
|
|
auth_strategy = keystone
|
|
|
|
[keystone_authtoken]
|
|
# ...
|
|
auth_url = http://controller:5000/v3
|
|
memcached_servers = controller:11211
|
|
auth_type = password
|
|
project_domain_name = default
|
|
user_domain_name = default
|
|
project_name = service
|
|
username = nova
|
|
password = NOVA_PASS
|
|
|
|
Replace ``NOVA_PASS`` with the password you chose for the ``nova`` user in
|
|
the Identity service.
|
|
|
|
.. note::
|
|
|
|
Comment out or remove any other options in the ``[keystone_authtoken]``
|
|
section.
|
|
|
|
* In the ``[DEFAULT]`` section, configure the ``my_ip`` option to use the
|
|
management interface IP address of the controller node:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
my_ip = 10.0.0.11
|
|
|
|
* In the ``[DEFAULT]`` section, enable support for the Networking service:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
use_neutron = True
|
|
firewall_driver = nova.virt.firewall.NoopFirewallDriver
|
|
|
|
.. note::
|
|
|
|
By default, Compute uses an internal firewall driver. Since the
|
|
Networking service includes a firewall driver, you must disable the
|
|
Compute firewall driver by using the
|
|
``nova.virt.firewall.NoopFirewallDriver`` firewall driver.
|
|
|
|
* In the ``[vnc]`` section, configure the VNC proxy to use the management
|
|
interface IP address of the controller node:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[vnc]
|
|
enabled = true
|
|
# ...
|
|
server_listen = $my_ip
|
|
server_proxyclient_address = $my_ip
|
|
|
|
* In the ``[glance]`` section, configure the location of the Image service
|
|
API:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[glance]
|
|
# ...
|
|
api_servers = http://controller:9292
|
|
|
|
* In the ``[oslo_concurrency]`` section, configure the lock path:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[oslo_concurrency]
|
|
# ...
|
|
lock_path = /var/lib/nova/tmp
|
|
|
|
* Due to a packaging bug, remove the ``log_dir`` option from the
|
|
``[DEFAULT]`` section.
|
|
|
|
* In the ``[placement]`` section, configure the Placement API:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[placement]
|
|
# ...
|
|
os_region_name = RegionOne
|
|
project_domain_name = Default
|
|
project_name = service
|
|
auth_type = password
|
|
user_domain_name = Default
|
|
auth_url = http://controller:5000/v3
|
|
username = placement
|
|
password = PLACEMENT_PASS
|
|
|
|
Replace ``PLACEMENT_PASS`` with the password you choose for the
|
|
``placement`` user in the Identity service. Comment out any other options
|
|
in the ``[placement]`` section.
|
|
|
|
#. Populate the nova-api database:
|
|
|
|
.. code-block:: console
|
|
|
|
# su -s /bin/sh -c "nova-manage api_db sync" nova
|
|
|
|
.. note::
|
|
|
|
Ignore any deprecation messages in this output.
|
|
|
|
#. Register the ``cell0`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
|
|
|
|
#. Create the ``cell1`` cell:
|
|
|
|
.. code-block:: console
|
|
|
|
# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

.. code-block:: console
|
|
|
|
# su -s /bin/sh -c "nova-manage db sync" nova
|
|
|
|
#. Verify nova cell0 and cell1 are registered correctly:
