|
||
services and performs the following operations:
|
||
|
||
- Install Memcached
|
||
|
||
- Install the repository server
|
||
|
||
- Install Galera
|
||
|
||
- Install RabbitMQ
|
||
|

#. Change to the ``/opt/openstack-ansible/playbooks`` directory.
|
||
|
||
#. Run the infrastructure setup playbook:
|
||
|
||
.. code-block:: shell-session
|
||
