Install and configure (SUSE)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This section describes how to install and configure the Image service,
|
|
code-named glance, on the controller node. For simplicity, this
|
|
configuration stores images on the local file system.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
Before you install and configure the Image service, you must
|
|
create a database, service credentials, and API endpoints.
|
|
|
|
#. 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
|
|
|
|
.. end
|
|
|
|
* Create the ``glance`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
MariaDB [(none)]> CREATE DATABASE glance;
|
|
|
|
.. end
|
|
|
|
* Grant proper access to the ``glance`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
|
|
IDENTIFIED BY 'GLANCE_DBPASS';
|
|
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
|
|
IDENTIFIED BY 'GLANCE_DBPASS';
|
|
|
|
.. end
|
|
|
|
Replace ``GLANCE_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
|
|
|
|
.. end
|
|
|
|
#. To create the service credentials, complete these steps:
|
|
|
|
* Create the ``glance`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack user create --domain default --password-prompt glance
|
|
|
|
User Password:
|
|
Repeat User Password:
|
|
+---------------------+----------------------------------+
|
|
| Field | Value |
|
|
+---------------------+----------------------------------+
|
|
| domain_id | default |
|
|
| enabled | True |
|
|
| id | 3f4e777c4062483ab8d9edd7dff829df |
|
|
| name | glance |
|
|
| options | {} |
|
|
| password_expires_at | None |
|
|
+---------------------+----------------------------------+
|
|
|
|
.. end
|
|
|
|
* Add the ``admin`` role to the ``glance`` user and
|
|
``service`` project:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack role add --project service --user glance admin
|
|
|
|
.. end
|
|
|
|
.. note::
|
|
|
|
This command provides no output.
|
|
|
|
* Create the ``glance`` service entity:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack service create --name glance \
|
|
--description "OpenStack Image" image
|
|
|
|
+-------------+----------------------------------+
|
|
| Field | Value |
|
|
+-------------+----------------------------------+
|
|
| description | OpenStack Image |
|
|
| enabled | True |
|
|
| id | 8c2c7f1b9b5049ea9e63757b5533e6d2 |
|
|
| name | glance |
|
|
| type | image |
|
|
+-------------+----------------------------------+
|
|
|
|
.. end
|
|
|
|
#. Create the Image service API endpoints:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack endpoint create --region RegionOne \
|
|
image public http://controller:9292
|
|

Install and configure components
|
|
--------------------------------
|
|
|
|
.. include:: note_configuration_vary_by_distribution.txt
|
|
|
|
|
|
.. note::
|
|
|
|
Starting with the Newton release, SUSE OpenStack packages are shipping
|
|
with the upstream default configuration files. For example
|
|
``/etc/glance/glance-api.conf``, with customizations in
|
|
``/etc/glance/glance-api.conf.d/``. While the following
|
|
instructions modify the default configuration files, adding new files
|
|
in ``/etc/glance/glance-api.conf.d`` achieves the same result.
|
|
|
|
|
|
|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper install openstack-glance \
|
|
openstack-glance-api
|
|
|
|
.. end
|
|
|
|
|
|
|
|
|
|
2. Edit the ``/etc/glance/glance-api.conf`` file and complete the
|
|
following actions:
|
|
|
|
* In the ``[database]`` section, configure database access:
|
|
|
|
.. path /etc/glance/glance.conf
|
|
.. code-block:: ini
|
|
|
|
[database]
|
|
# ...
|
|
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
|
|
|
|
.. end
|
|
|
|
Replace ``GLANCE_DBPASS`` with the password you chose for the
|
|
Image service database.
|
|
|
|
* In the ``[keystone_authtoken]`` and ``[paste_deploy]`` sections,
|
|
configure Identity service access:
|
|
|
|
.. path /etc/glance/glance.conf
|
|
.. code-block:: ini
|
|
|
|
[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 = glance
|
|
password = GLANCE_PASS
|
|
|
|
[paste_deploy]
|
|
# ...
|
|
flavor = keystone
|
|
|
|
.. end
|
|
|
|
Replace ``GLANCE_PASS`` with the password you chose for the
|
|
``glance`` user in the Identity service.
|
|
|
|
.. note::
|
|
|
|
Comment out or remove any other options in the
|
|
``[keystone_authtoken]`` section.
|
|
|
|
* In the ``[glance_store]`` section, configure the local file
|
|
system store and location of image files:
|
|
|
|
.. path /etc/glance/glance.conf
|
|
.. code-block:: ini
|
|
|
|
[glance_store]
|
|
# ...
|
|
stores = file,http
|
|
default_store = file
|
|
filesystem_store_datadir = /var/lib/glance/images/
|
|
|
|
.. end
|
|
|
|
Finalize installation
|
|
---------------------
|
|
|
|
|
|
* Start the Image services and configure them to start when
|
|
the system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable openstack-glance-api.service
|
|
# systemctl start openstack-glance-api.service
|
|
|
|
.. end
|
|
|
|
