Install/Enable Quantum lbass (load balancer) feature?

Hi all!
How can we install/enable the Quantum-lbaas (load balancer) feature for Openstack Grizzly? I dont see any docs for RHEL/CentOS specific installs.
I used RDO to deploy Openstack on a single node.

Thank you! Jake

Hi Jake,

Regarding lbaas in grizzly working on RHEL/Centos - it may be problematic
as host operation system must support network namespaces.
If you do have support for network namespaces then you need to do the
following steps to setup lbaas service in quantum:

1) specify lbaas plugin in quantum.conf:
service_plugins= lbaas_plugin_classpath.
check quantum/plugins/services/agent_loadbalancer/plugin.py for correct
path as currently the name and path has changed.

2) to enable lbaas service in horizon you need to do the following:
add the following piece of code
to horizon/openstack_dashboard/local/local_settings.py :

OPENSTACK_QUANTUM_NETWORK = {
'enable_lb': False
}

3) start quantum-lbaas-agent on the host providing quantum.conf and
lbaas-agent.ini. lbaas-agent.ini should reflect core plugin configuration
(should have proper interface driver)

Note that if host os has no namespace support, all of above will work (e.g.
REST API will be functional), but you would not be able to deploy
loadbalancer as lbaas agent can only work with namespaces.

Thanks,
Eugene.

Re: Install/Enable Quantum lbass (load balancer) feature? [In reply to]

I have enabled LBaas on my openstack, but after adding a pool, vip, members, and monitor successfully I am still unable to get load balancing working.
I found this blog to help me so far http://kimizhang.wordpress.com/2013/08/08/openstack-grizzly-quantum-advanced-features-2/

When I run # ps -ef | grep haproxy I dont get much:
root 27508 2718 0 14:16 pts/1 00:00:00 grep haproxy

My logs show an issue with haproxy:

RuntimeError:

Any ideas?

Do you have haproxy package installed on your host?

Re: Install/Enable Quantum lbass (load balancer) feature? [In reply to]

Good call!
Looks like i did but the service wont start. Do you have a sample haproxy.cfg file that will work with Openstack?

Thank you

Yes this is my Kernel> 2.6.32-358.114.1.openstack.el6.x86_64
and I enable:

use_namespaces = True

ovs_use_veth = True

in /etc/quantum/dhcp_agent.ini and etc/quantum/l3_agent.ini

Re: Install/Enable Quantum lbass (load balancer) feature? [In reply to]

use_namespaces has no effect, lbaas agent in grizzly always relies on
namespace support.

Could you execute the failing command manually?
That needs to be done after you create a vip for the pool.
The command should look like this:
sudo quantum-rootwrap /etc/quantum/rootwrap.conf ip netns exec
qlbaas-e10951cd-4cca-4ba4-acc0-0ccde6817029 haproxy -f /var
/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/conf -p
/var/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/pid

<e10951cd-4cca-4ba4-acc0-0ccde6817029> should be replaced with actual
pool_id
Could you also verify that path and file /lib/quantum/lbaas/e10951cd-
4cca-4ba4-acc0-0ccde6817029/conf exist?

Thanks,
Eugene.

Re: Install/Enable Quantum lbass (load balancer) feature? [In reply to]

After I reboot my host my dashboard won't load anymore so after I revert my settings from backup I'll give that a try.

Thank you! Have a great weekend

Re: Install/Enable Quantum lbass (load balancer) feature? [In reply to]

Ok i started from scratch and now everything is working just fine. Thank you for all your help.
In the end I believe it was because I did not have haproxy installed.

Subject: Re: [Openstack] Install/Enable Quantum lbass (load balancer) feature?

use_namespaces has no effect, lbaas agent in grizzly always relies on namespace support.

Could you execute the failing command manually?
That needs to be done after you create a vip for the pool.
The command should look like this:
sudo quantum-rootwrap /etc/quantum/rootwrap.conf ip netns exec qlbaas-e10951cd-4cca-4ba4-acc0-0ccde6817029 haproxy -f /var
/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/conf -p /var/lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/pid

<e10951cd-4cca-4ba4-acc0-0ccde6817029> should be replaced with actual pool_id

Could you also verify that path and file /lib/quantum/lbaas/e10951cd-4cca-4ba4-acc0-0ccde6817029/conf exist?

Thanks,
Eugene.
