The installation process requires running three main playbooks:
|
|
|
|
- The ``setup-hosts.yml`` Ansible foundation playbook prepares the target
|
|
hosts for infrastructure and OpenStack services, builds and restarts
|
|
containers on target hosts, and installs common components into containers
|
|
on target hosts.
|
|
|
|
- The ``setup-infrastructure.yml`` Ansible infrastructure playbook installs
|
|
infrastructure services: Memcached, the repository server, Galera and
|
|
RabbitMQ.
|
|
|
|
- The ``setup-openstack.yml`` OpenStack playbook installs OpenStack services,
|
|
including Identity (keystone), Image (glance), Block Storage (cinder),
|
|
Compute (nova), Networking (neutron), etc.
|
|
|
|
Checking the integrity of the configuration files
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Before running any playbook, check the integrity of the configuration files.
|
|
|
|
#. Ensure that all the files edited in the ``/etc/openstack_deploy`` directory are
|
|
Ansible `YAML compliant <http://docs.ansible.com/ansible/YAMLSyntax.html>`_.
|
|
|
|
#. Check the integrity of your YAML files.
|
|
|
|
.. note::
|
|
|
|
To check your YAML syntax online, you can use the `YAML Lint program <http://www.yamllint.com/>`_.
|
|
|
|
#. Change to the ``/opt/openstack-ansible/playbooks`` directory, and run the
|
|
following command:
|
|
|
|
.. code-block:: console
|
|
|
|
# openstack-ansible setup-infrastructure.yml --syntax-check
|
|
|
|
#. Recheck that all indentation is correct. This is important because the
|
|
syntax of the configuration files can be correct while not being meaningful
|
|
for OpenStack-Ansible.
|
|
|
|
Run the playbooks to install OpenStack
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
#. Change to the ``/opt/openstack-ansible/playbooks`` directory.
|
|
|
|
#. Run the host setup playbook:
|
|
|
|
.. code-block:: console
|
|
|
|
# openstack-ansible setup-hosts.yml
|
|
|
|
Confirm satisfactory completion with zero items unreachable or
|
|
failed:
|
|
|

.. code-block:: console

The ``wsrep_cluster_size`` field indicates the number of nodes
|
|
in the cluster and the ``wsrep_cluster_status`` field indicates
|
|
primary.

|
|
#. Run the OpenStack setup playbook:
|
|
|
|
.. code-block:: console
|
|
|
|
# openstack-ansible setup-openstack.yml
|
|
|
|
Confirm satisfactory completion with zero items unreachable or
