Install and configure
|
|
~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
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.
|
|
|
|
.. only:: obs or rdo or ubuntu
|
|
|
|
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
|
|
|
|
* Create the ``glance`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
CREATE DATABASE glance;
|
|
|
|
* Grant proper access to the ``glance`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
|
|
IDENTIFIED BY 'GLANCE_DBPASS';
|
|
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
|
|
IDENTIFIED BY 'GLANCE_DBPASS';
|
|
|
|
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
|
|
|
|
$ source admin-openrc.sh
|
|
|
|
#. To create the service credentials, complete these steps:
|
|
|
|
* Create the ``glance`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack user create --password-prompt glance
|
|
User Password:
|
|
Repeat User Password:

|
|
| name | glance |
|
|
+-----------+----------------------------------+
|
|
|
|
* Add the ``admin`` role to the ``glance`` user and
|
|
``service`` project:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack role add --project service --user glance admin
|
|
|
|
.. note::
|
|
|
|
This command provides no output.
|
|
|
|
* Create the ``glance`` service entity:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack service create --name glance \
|
|
--description "OpenStack Image service" image
|

+-------------+----------------------------------+
|
|
| Field | Value |
|

|
|
| name | glance |
|
|
| type | image |
|

|
|
|
|
#. Create the Image service API endpoints:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack endpoint create --region RegionOne \
|
|
image public http://controller:9292

Install and configure components
|
|
--------------------------------
|
|
|
|
.. only:: obs or rdo or ubuntu
|
|
|
|
.. include:: shared/note_configuration_vary_by_distribution.rst
|
|
|
|
.. only:: obs

|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# zypper install openstack-glance python-glanceclient
|
|
|
|
.. only:: rdo
|

|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install openstack-glance python-glance python-glanceclient
|
|
|
|
.. The installation of python-glance is a workaround
|
|
for bug: https://bugzilla.redhat.com/show_bug.cgi?id=1213545
|
|
|
|
.. only:: ubuntu
|
|
|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# apt-get install glance python-glanceclient
|
|
|
|
.. only:: obs or rdo or ubuntu
|
|
|
|
2. Edit the ``/etc/glance/glance-api.conf`` file and complete
|
|
the following actions:
|
|
|
|
* In the ``[database]`` section, configure database access:
|
|
|
|
.. code-block:: ini
|
|
|
|
[database]
|
|
...
|
|
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
|
|
|
|
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:
|
|
|
|
.. code-block:: ini
|
|
|
|
[keystone_authtoken]
|
|
...
|
|
auth_uri = http://controller:5000
|
|
auth_url = http://controller:35357
|
|
auth_plugin = password
|
|
project_domain_id = default
|
|
user_domain_id = default
|
|
project_name = service
|
|
username = glance
|
|
password = GLANCE_PASS
|
|
|
|
[paste_deploy]
|
|
...
|
|
flavor = keystone
|
|
|
|
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:
|
|
|
|
.. code-block:: ini
|
|
|
|
[glance_store]
|
|
...
|
|
default_store = file
|
|
filesystem_store_datadir = /var/lib/glance/images/
|
|
|
|
* In the ``[DEFAULT]`` section, configure the ``noop``
|
|
notification driver to disable notifications because
|
|
they only pertain to the optional Telemetry service:
|
|
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
notification_driver = noop
|
|
|
|
The Telemetry chapter provides an Image service configuration
|
|
that enables notifications.
|
|
|
|
* (Optional) To assist with troubleshooting,
|
|
enable verbose logging in the ``[DEFAULT]`` section:
|
|
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
verbose = True
|
|
|
|
3. Edit the ``/etc/glance/glance-registry.conf`` file and
|
|
complete the following actions:
|
|
|
|
* In the ``[database]`` section, configure database access:
|
|
|
|
.. code-block:: ini
|
|
|
|
[database]
|
|
...
|
|
connection = mysql+pymysql://glance:GLANCE_DBPASS@controller/glance
|
|
|
|
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:
|
|
|
|
.. code-block:: ini
|
|
|
|
[keystone_authtoken]
|
|
...
|
|
auth_uri = http://controller:5000
|
|
auth_url = http://controller:35357
|
|
auth_plugin = password
|
|
project_domain_id = default
|
|
user_domain_id = default
|
|
project_name = service
|
|
username = glance
|
|
password = GLANCE_PASS
|
|
|
|
[paste_deploy]
|
|
...
|
|
flavor = keystone
|
|
|
|
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 ``[DEFAULT]`` section, configure the ``noop`` notification
|
|
driver to disable notifications because they only pertain to the
|
|
optional Telemetry service:
|
|
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
notification_driver = noop
|
|
|
|
The Telemetry chapter provides an Image service configuration
|
|
that enables notifications.
|
|
|
|
* (Optional) To assist with troubleshooting,
|
|
enable verbose logging in the ``[DEFAULT]`` section:
|
|
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
...
|
|
verbose = True
|
|
|
|
.. only:: rdo or ubuntu
|
|
|
|
4. Populate the Image service database:
|
|
|
|
.. code-block:: console
|
|
|
|
# su -s /bin/sh -c "glance-manage db_sync" glance
|
|
|
|
.. only:: debian
|
|
|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# apt-get install glance python-glanceclient
|
|
|
|
#. Respond to prompts for
|
|
:doc:`database management <debconf/debconf-dbconfig-common>`,
|
|
:doc:`Identity service credentials <debconf/debconf-keystone-authtoken>`,
|
|
:doc:`service endpoint registration <debconf/debconf-api-endpoints>`,
|
|
and :doc:`message broker credentials <debconf/debconf-rabbitmq>`.
|
|
|
|
#. Select the ``keystone`` pipeline to configure the Image service
|
|
to use the Identity service:
|
|
|
|
.. image:: figures/debconf-screenshots/glance-common_pipeline_flavor.png
|
|
:width: 100%
|
|
|
|
Finalize installation
|
|
---------------------
|
|
|
|
.. only:: obs or rdo
|
|
|
|
#. Start the Image service services and configure them to start when
|
|
the system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable openstack-glance-api.service \
|
|
openstack-glance-registry.service
|
|
# systemctl start openstack-glance-api.service \
|
|
openstack-glance-registry.service
|
|
|
|
.. only:: ubuntu or debian
|
|
|
|
#. Restart the Image service services:
|
|
|
|
.. code-block:: console
|
|
|
|
# service glance-registry restart
|
|
# service glance-api restart
|
|
|
|
.. only:: ubuntu
|
|
|
|
2. By default, the Ubuntu packages create an SQLite database.
|
|
|
|
Because this configuration uses an SQL database server, you can
|
|
remove the SQLite database file:
|
|
|
|
.. code-block:: console
|
|
|
|
# rm -f /var/lib/glance/glance.sqlite
|
