Load Balancer as a Service (LBaaS V2.0)
1.安装服务以及配置
yum install openstack-neutron-lbaas haproxy
修改/etc/neutron/neutron.conf 的[DEFAULT]部分：
crudini --set /etc/neutron/neutron.conf DEFAULT service_plugins router,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2
如果已有定义的 plugins，可以用以下方是区分：
service_plugins = [already defined plugins], neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2
修改/etc/neutron/neutron_lbaas.conf的[service_providers]选项:
crudini --set /etc/neutron/neutron_lbaas.conf service_providers service_provider LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default
修改/etc/neutron/lbaas_agent.ini的[DEFAULT]部分：
crudini --set /etc/neutron/lbaas_agent.ini DEFAULT interface_driver neutron.agent.linux.interface.OVSInterfaceDriver
更新neutron数据库
neutron-db-manage --service lbaas --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugin.ini upgrade head
重启服务
systemctl restart neutron-server
systemctl enable neutron-lbaasv2-agent.service
systemctl start neutron-lbaasv2-agent.service
2.添加 LBaas 到 Dashboard（默认新版ALLINONE Dashboard 没有安装lbassV2）
安装 dashboard plugin
git clone https://git.openstack.org/openstack/neutron-lbaas-dashboard
cd neutron-lbaas-dashboard
git checkout stable/mitaka
python setup.py install
cp neutron-lbaas-dashboard/enabled/_1481_project_ng_loadbalancersv2_panel.py /usr/share/openstack-dashboard/openstack_dashboard/local/enabled/
修改配置文件 /etc/openstack-dashboard/local_settings:
OPENSTACK_NEUTRON_NETWORK = {
...
'enable_lb': True
...
重启httpd服务
systemctl restart httpd
3.创建 Load balancer
neutron lbaas-loadbalancer-create --name test-lb 474c2c02-3c70-46d5-bb5a-761ceb46827f
创建vip_port的安全组
neutron security-group-create lbaas
eutron security-group-rule-create \
--direction ingress \
--protocol tcp \
--port-range-min 80 \
--port-range-max 80 \
--remote-ip-prefix 0.0.0.0/0 \
lbaas
neutron security-group-rule-create \
--direction ingress \
--protocol icmp \
lbaas
neutron port-update \
> --security-group lbaas \
> 7dabd3e1-3fcb-4699-97da-9a11676f6269(注:vip_port_id)
创建 Listener :
neutron lbaas-listener-create \
--name test-lb-http \
--loadbalancer test-lb \
--protocol HTTP \
--protocol-port 80
创建 Pool :
neutron lbaas-pool-create \
--name test-lb-pool-http \
--lb-algorithm ROUND_ROBIN \
--listener test-lb-http \
--protocol HTTP
创建 Member :
neutron lbaas-member-create \
--subnet private-subnet \
--address 10.0.0.5 \
--protocol-port 80 \
test-lb-pool-http
neutron lbaas-member-create \
--subnet private-subnet \
--address 10.0.0.4 \
--protocol-port 80 \
test-lb-pool-http
创建 Health monitor :
neutron lbaas-healthmonitor-create \
--delay 5 \
--max-retries 2 \
--timeout 10 \
--type HTTP \
--pool test-lb-pool-http
绑定浮动IP:
neutron floatingip-associate FLOATINGIP_ID LOAD_BALANCER_PORT_ID
查了很久的资料，终于可以实现lbaasv2.0的功能了，请支持原创，谢谢。
