Open Stack

Hi,

I am not sure about Ubuntu. I was never able to get openstack working on Ubuntu so I gave up, but this is the process I used to set up LBaas on CentOS
Please replace commands with Ubuntu style commands


■　Add Quantum LBaas service to Openstack RDO

1. install haproxy if it not already installed
# yum install haproxy -y
# reboot

2. Make sure you have the modified kernel that supports namespaces. (not necessary on Ubuntu. Already supports namespaces)
# uname -r 
Should look something like this. Your version may be different -> 2.6.32-358.114.1.openstack.el6.x86_64

3. Add following line in /etc/quantum/quantum.conf on your quantum-server host and restart quantum-server
# vi /etc/quantum/quantum.conf
---------------------------------
service_plugins = quantum.plugins.services.agent_loadbalancer.plugin.LoadBalancerPlugin
---------------------------------
# /etc/init.d/quantum-server restart

4. Insert the following line in /etc/openstack-dashboard/local_settings on horizon host, and restart httpd. This enables LBaaS operations on Dashboard WebUI
# vi /etc/openstack-dashboard/local_settings
---------------------------------                                                                                                                 
OPENSTACK_QUANTUM_NETWORK = {   
'enable_lb': True
}
---------------------------------
# service httpd restart

5. Update the following lines in /etc/quantum/lbaas_agent.ini , then restart quantum-lbaas-agent service
# vi /etc/quantum/lbaas_agent.ini
---------------------------------
ovs_use_veth = True
use_namespaces = True
interface_driver = quantum.agent.linux.interface.OVSInterfaceDriver
device_driver = quantum.plugins.services.agent_loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver
user_group = haproxy
---------------------------------
# /etc/init.d/quantum-lbaas-agent restart


This process worked for me, you could give it a try.

Best,
Jake
