Install and configure controller node for Red Hat Enterprise Linux and CentOS
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This section describes how to install and configure the placement service on
|
|
the controller node.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
Before you install and configure the placement service, you must create
|
|
a database, service credentials, and API endpoints.
|
|
|
|
Create Database
|
|
^^^^^^^^^^^^^^^
|
|
|
|
#. To create the database, 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 ``placement`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
MariaDB [(none)]> CREATE DATABASE placement;
|
|
|
|
* Grant proper access to the database:
|
|
|
|
.. code-block:: console
|
|
|
|
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' \
|
|
IDENTIFIED BY 'PLACEMENT_DBPASS';
|
|
MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' \
|
|
IDENTIFIED BY 'PLACEMENT_DBPASS';
|
|
|
|
Replace ``PLACEMENT_DBPASS`` with a suitable password.
|
|
|
|
* Exit the database access client.
|
|
|
|
Configure User and Endpoints
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. include:: endpoints.rst
|
|
|
|
Install and configure components
|
|
--------------------------------
|
|
|
|
.. include:: note_configuration_vary_by_distribution.rst
|
|
|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install openstack-placement-api
|
|
|
|
#. Edit the ``/etc/placement/placement.conf`` file and complete the following
|
|
actions:
|
|
|
|
* In the ``[placement_database]`` section, configure database access:
|
|
|
|
.. path /etc/placement/placement.conf
|
|
.. code-block:: ini
|
|
|
|
[placement_database]
|
|
# ...
|
|
connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement
|
|
|
|
Replace ``PLACEMENT_DBPASS`` with the password you chose for the placement
|
|
database.
|
|
|
|
* In the ``[api]`` and ``[keystone_authtoken]`` sections, configure Identity
|
|
service access:
|
|
|
|
.. path /etc/placement/placement.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 = placement
|
|
password = PLACEMENT_PASS
|
|
|
|
Replace ``PLACEMENT_PASS`` with the password you chose for the
|
|
``placement`` user in the Identity service.
|
|
|
|
.. note::
|
|
|
|
Comment out or remove any other options in the ``[keystone_authtoken]``
|
|
section.
|
|
|
|
#. Populate the ``placement`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
# su -s /bin/sh -c "placement-manage db sync" placement
|
|
|
|
.. note::
|

|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl restart httpd
