Install and configure compute node
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The compute node handles connectivity and security groups for instances.
|
|
|
|
|
|
|
|
Install the components
|
|
----------------------
|
|
|
|
.. todo:
|
|
|
|
https://bugzilla.redhat.com/show_bug.cgi?id=1334626
|
|
|
|
.. code-block:: console
|
|
|
|
# yum install openstack-neutron-openvswitch
|
|
|
|
.. end
|
|
|
|
|
|
|
|
Configure the common component
|
|
------------------------------
|
|
|
|
The Networking common component configuration includes the
|
|
authentication mechanism, message queue, and plug-in.
|
|
|
|
.. include:: shared/note_configuration_vary_by_distribution.rst
|
|
|
|
* Edit the ``/etc/neutron/neutron.conf`` file and complete the following
|
|
actions:
|
|
|
|
* In the ``[database]`` section, comment out any ``connection`` options
|
|
because compute nodes do not directly access the database.
|
|
|
|
* In the ``[DEFAULT]`` section, configure ``RabbitMQ``
|
|
message queue access:
|
|
|
|
.. path /etc/neutron/neutron.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
transport_url = rabbit://openstack:RABBIT_PASS@controller
|
|
|
|
.. end
|
|
|
|
Replace ``RABBIT_PASS`` with the password you chose for the ``openstack``
|
|
account in RabbitMQ.
|
|
|
|
* In the ``[DEFAULT]`` and ``[keystone_authtoken]`` sections, configure
|
|
Identity service access:
|
|
|
|
.. path /etc/neutron/neutron.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
auth_strategy = keystone
|
|
|
|
[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 = neutron
|
|
password = NEUTRON_PASS
|
|
|
|
.. end
|
|
|
|
Replace ``NEUTRON_PASS`` with the password you chose for the ``neutron``
|
|
user in the Identity service.
|
|
|
|
.. note::
|
|
|
|
Comment out or remove any other options in the
|
|
``[keystone_authtoken]`` section.
|
|
|
|
|
|
* In the ``[oslo_concurrency]`` section, configure the lock path:
|
|
|
|
.. path /etc/neutron/neutron.conf
|
|
.. code-block:: ini
|
|
|
|
[oslo_concurrency]
|
|
# ...
|
|
lock_path = /var/lib/neutron/tmp
|
|
|
|
.. end
|
|
|
|
|
|
|
|
Configure networking options
|
|
----------------------------
|
|
|
|
Choose the same networking option that you chose for the controller node to
|
|
configure services specific to it. Afterwards, return here and proceed to
|
|
:ref:`neutron-compute-compute-rdo`.
|
|
|
|

.. _neutron-compute-compute-rdo:
|
|
|
|
Configure the Compute service to use the Networking service
|
|
-----------------------------------------------------------
|
|
|
|
* Edit the ``/etc/nova/nova.conf`` file and complete the following actions:
|
|
|
|
* In the ``[neutron]`` section, configure access parameters:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[neutron]
|
|
# ...
|
|
auth_url = http://controller:5000
|
|
auth_type = password
|
|
project_domain_name = Default
|
|
user_domain_name = Default
|
|
region_name = RegionOne
|
|
project_name = service
|
|
username = neutron
|
|
password = NEUTRON_PASS
|
|
|
|
.. end
|
|
|
|
Replace ``NEUTRON_PASS`` with the password you chose for the ``neutron``
|
|
user in the Identity service.
|
|
|
|
See the :nova-doc:`compute service configuration guide <configuration/config.html#neutron>`
|
|
for the full set of options including overriding the service catalog
|
|
endpoint URL if necessary.

|
Finalize installation
|
|
---------------------
|
|
|
|
|
|
#. Restart the Compute service:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl restart openstack-nova-compute.service
|
|
|
|
.. end
|
|
|
|
#. Start the Linux bridge agent and configure it to start when the
|
|
system boots:
|
|
|
|
.. code-block:: console
|
|
|
|
# systemctl enable neutron-openvswitch-agent.service
|
|
# systemctl start neutron-openvswitch-agent.service
|
|
|
|
.. end
