How to configure LBaaS, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

First enable the LBaaS service in the configuration.

Neutron provides LBaaS services through lbaas plugin and lbaas agent.

Lbaas plugin runs on the control node with Neutron Server. Lbaas agent runs on network nodes.

For our experimental environment, the control node and the network node are both devstack-controller.

Configure LBaaS agent

Where Neutron configures LBaaS agent is / etc/neutron/services/loadbalancer/haproxy/lbaas_agent.ini.

Define interface_driver:

The function of interface_driver is to set the network interface driver of load balancer, and there are two options:

Linux Bridge

Interface_driver = neutron.agent.linux.interface.BridgeInterfaceDriver

Open vSwitch

Interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver

Configure LBaaS plugin

Set to enable LBaaS plugin in / etc/neutron/neutron.conf

Set service provider in / etc/neutron/neutron_lbaas.conf

As you can see from the comments, in addition to the default HAProxy,Neutron, third-party provider is also supported, such as radware,VMWareEdge.

Restart the neutron service to ensure that LBaaS is running properly.

We will practice the following LBaaS environment.

The environment is described as follows:

1. Create a Pool "web servers".

two。 The two pool member "WEB1" and "WEB2" are both instance running Ubuntu cloud image.

3. Load balancer VIP is associated with floating IP.

4. Client on the public network accesses web server through floating IP.
