Placement service has to be installed and configured with user and endpoints before Nova installation. But in stein release it is not mentioned in the prerequisites of Nova. Added reference to Placement installation guide in the prerequisites section of nova installation guide. Change-Id: I6af43a24dc5b3575016f092268d98cc720249d93 Closes-Bug: #1829032

Install and configure controller node for openSUSE and SUSE Linux Enterprise
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
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 -u root -p
|
|
|
|
* 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:
|
|
+---------------------+----------------------------------+
|
|
| Field | Value |
|
|
+---------------------+----------------------------------+
|
|
| domain_id | default |
|
|
| enabled | True |
|
|
| id | 8a7dbf5279404537b1c7b86c033620fe |
|
|
| 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
|
|
|
|
+-------------+----------------------------------+

|
| Field | Value |
|

|
|
| name | nova |
|
|
| type | compute |
|
|
+-------------+----------------------------------+
|
|
|
|
#. Create the Compute API service endpoints:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack endpoint create --region RegionOne \
|
|
compute public http://controller:8774/v2.1

#. Install Placement service and configure user and endpoints:
|
|
|
|
* Refer to the :placement-doc:`Placement service install guide
|
|
<install/install-obs.html#configure-user-and-endpoints>`
|
|
for more information.

Install and configure components

.. include:: shared/note_configuration_vary_by_distribution.rst
|
|
|
|
.. note::
|
|
|
|
As of the Newton release, SUSE OpenStack packages are shipped with the
|
|
upstream default configuration files. For example, ``/etc/nova/nova.conf``
|
|
has customizations in ``/etc/nova/nova.conf.d/010-nova.conf``. While the
|
|
following instructions modify the default configuration file, adding a new
|
|
file in ``/etc/nova/nova.conf.d`` achieves the same result.
|
|
|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper install \
|
|
openstack-nova-api \
|
|
openstack-nova-scheduler \
|
|
openstack-nova-conductor \
|
|
openstack-nova-novncproxy \
|
|
iptables
|
|
|
|
#. Edit the ``/etc/nova/nova.conf`` file and complete the following actions:
|
|
|
|
* In the ``[DEFAULT]`` section, enable only the compute and metadata
|
|
APIs:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
enabled_apis = osapi_compute,metadata
|
|
|
|
* 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:5672/
|
|
|
|
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]
|
|
# ...
|
|
www_authenticate_uri = http://controller:5000/
|
|
auth_url = http://controller:5000/
|
|
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
|
|
|
|
* Configure the ``[neutron]`` section of **/etc/nova/nova.conf**. Refer to
|
|
the :neutron-doc:`Networking service install guide
|
|
<install/controller-install-obs.html#configure-the-compute-service-to-use-the-networking-service>`
|
|
for more details.
|
|
|
|
* 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/run/nova
|
|
|
|
* In the ``[placement]`` section, configure access to the Placement
|
|
service:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[placement]
|
|
# ...
|
|
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`` service user created when installing
|
|
:placement-doc:`Placement <install/>`. Comment out or remove any other
|
|
options in the ``[placement]`` section.
|
|
|
|
#. Populate the ``nova-api`` database:
|
|
|
|
.. code-block:: console
