LBAAS_Openstack.txt

#LBAAS v2

- On Controller & Network Node:

yum upgrade
yum -y install openstack-neutron-lbaas haproxy


- Enable the LoadBalancerPluginv2 inside the /etc/neutron/neutron.conf --

crudini --set /etc/neutron/neutron.conf DEFAULT service_plugins router,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2

- Enable the HAProxy namespace driver inside the/etc/neutron/neutron_lbaas.conf file

crudini --set /etc/neutron/neutron_lbaas.conf service_providers service_provider LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

- In /etc/neutron/lbaas_agent.ini change the 

[DEFAULT]
interface_driver = linuxbridge # Or neutron.agent.linux.interface.OVSInterfaceDriver

- Run database migration
neutron-db-manage --subproject neutron-lbaas upgrade head

- Source Adminrc
. adminrc

- Restart Neutron service and LBAAS Agent

service neutron-server restart
service neutron-lbaasv2-agent restart

- Check the status:

neutron agent-list --fields agent_type --fields alive
+----------------------+-------+
| agent_type           | alive |
+----------------------+-------+
| Open vSwitch agent   | :-)   |
| Metadata agent       | :-)   |
| DHCP agent           | :-)   |
| Loadbalancerv2 agent | :-)   |
| L3 agent             | :-)   |

Add LBaaS panels to Dashboard¶
The Dashboard panels for managing LBaaS v2 are available starting with the Mitaka release.

Clone the neutron-lbaas-dashboard repository and check out the release branch that matches the installed version of Dashboard:

$ git clone https://git.openstack.org/openstack/neutron-lbaas-dashboard
$ cd neutron-lbaas-dashboard
$ git checkout OPENSTACK_RELEASE
Install the Dashboard panel plug-in:

$ python setup.py install

(If you get pbr error do this:
yum install http://cbs.centos.org/kojifiles/packages/python-pbr/2.0.0/1.el7/noarch/python2-pbr-2.0.0-1.el7.noarch.rpm)

Copy the _1481_project_ng_loadbalancersv2_panel.py file from the neutron-lbaas-dashboard/enabled directory into the Dashboard openstack_dashboard/local/enabled directory.

This step ensures that Dashboard can find the plug-in when it enumerates all of its available panels.

Enable the plug-in in Dashboard by editing the local_settings.py file and setting enable_lb to True in the OPENSTACK_NEUTRON_NETWORK dictionary.

If Dashboard is configured to compress static files for better performance (usually set through COMPRESS_OFFLINE in local_settings.py), optimize the static files again:

$ ./manage.py collectstatic
$ ./manage.py compress
Restart Apache to activate the new panel:

$ sudo service apache2 restart
To find the panel, click on Project in Dashboard, then click the Network drop-down menu and select Load Balancers.
