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-linuxbridge ebtables ipset .. 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`. .. toctree:: :maxdepth: 1 compute-install-option1-rdo.rst compute-install-option2-rdo.rst .. _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 ` 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-linuxbridge-agent.service # systemctl start neutron-linuxbridge-agent.service .. end
