Configure Load-Balancing-as-a-Service (LBaaS)

Install the agent:

# apt-get install neutron-lbaas-agent

Enable the HAProxy plug-in using the service_provider parameter in the /etc/neutron/neutron.conf file:

service_provider = LOADBALANCER:Haproxy:neutron.services.loadbalancer.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

Enable the load balancer plugin using service_plugin in the /etc/neutron/neutron.conf file:

service_plugins = neutron.services.loadbalancer.plugin.LoadBalancerPlugin

Enable the HAProxy load balancer in the /etc/neutron/lbaas_agent.ini file:

device_driver = neutron.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver

Select the required driver in the /etc/neutron/lbaas_agent.ini file:

Enable the Open vSwitch LBaaS driver:

interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver

Or enable the Linux Bridge LBaaS driver:

interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver

Apply the new settings by restarting the neutron-server and neutron-lbaas-agent services.

	Upgrade from Havana to Icehouse
	There were changes in LBaaS server-agent communications in Icehouse so during Havana to Icehouse transition make sure to upgrade both server and agent sides before actual use of the load balancing service.

Enable Load Balancing in the Project section of the Dashboard user interface:

Change the enable_lb option to True in the /etc/openstack-dashboard/local_settings file:

OPENSTACK_NEUTRON_NETWORK = {'enable_lb': True,

Apply the new settings by restarting the httpd service. You can now view the Load Balancer management options in dashboard's Project view.
