Configuring the Network Load Balancing Service (Optional)
|
|
---------------------------------------------------------
|
|
|
|
The OpenStack Networking Service, Neutron, includes a Load Balancer as a
|
|
Service (LBaaS). This service lets you configure a load balancer that runs
|
|
outside of your instances and directs traffic to your instances. A common use
|
|
case is when you want to use multiple instances to serve web pages and want to
|
|
meet high performance or availability goals.
|
|
|
|
OpenStack-Ansible currently provides the OpenStack Neutron LBaaS service using
|
|
HAProxy as the load balancer.
|
|
|
|
The following procedure describes how to modify the
|
|
``/etc/openstack_deploy/user_variables.yml`` file to enable LBaaS.
|
|
|
|
#. Override the default list of Neutron plugins used in order to include
|
|
``neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPlugin``:
|
|
|
|
.. code-block:: yaml
|
|
|
|
neutron_plugin_base:
|
|
- neutron.services.l3_router.l3_router_plugin.L3RouterPlugin
|
|
- neutron.services.metering.metering_plugin.MeteringPlugin
|
|
- neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPlugin
|
|
|
|
#. Execute the Neutron install playbook in order to update the configuration
|
|
of the Neutron Agents:
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# cd /opt/openstack-ansible/playbooks
|
|
# openstack-ansible os-neutron-install.yml
|
|
|
|
#. Execute the Horizon install playbook in order to update the Horizon
|
|
configuration to show the LBaaS panels:
|
|
|
|
.. code-block:: shell-session
|
|
|
|
# cd /opt/openstack-ansible/playbooks
|
|
# openstack-ansible os-horizon-install.yml
|
|
|
|
The LBaaS default configuration options may be changed through the
|
|
`conf override`_ mechanism using the ``neutron_lbaas_agent_ini_overrides``
|
|
dict.
|
|
|
|
.. _conf override: http://docs.openstack.org/developer/openstack-ansible/install-guide/configure-openstack.html
