Adding a compute host
|
||
=====================
|
||
|
||
Use the following procedure to add a compute host to an operational
|
||
cluster.
|
||
|
||
#. Configure the host as a target host. See `Chapter 3, *Target
|
||
hosts* <targethosts.html>`_ for more information.
|
||
|
||
#. Edit the ``/etc/openstack_deploy/openstack_user_config.yml`` file and
|
||
add the host to the ``compute_hosts`` stanza.
|
||
|
||
If necessary, also modify the ``used_ips`` stanza.
|
||
|
||
#. If the cluster is utilizing Telemetry/Metering (Ceilometer),
|
||
edit the ``/etc/openstack_deploy/conf.d/ceilometer.yml`` file and add the host to
|
||
the ``metering-compute_hosts`` stanza.
|
||
|
||
#. Run the following commands to add the host. Replace
|
||
``NEW_HOST_NAME`` with the name of the new host.
|
||
|
||
.. code-block:: shell-session
|
||
|
||
# cd /opt/openstack-ansible/playbooks
|
||
# openstack-ansible setup-hosts.yml --limit NEW_HOST_NAME
|
||
# openstack-ansible setup-openstack.yml --skip-tags nova-key-distribute --limit NEW_HOST_NAME
|
||
# openstack-ansible setup-openstack.yml --tags nova-key --limit compute_hosts
