openstack配置LBaas

openstack 版本为rocky

neutron-controller配置

yum install openstack-neutron-lbaas -y
修改下面的配置文件
vi /etc/neutron/neutron.conf（router是之前原有，只增加后面的）
service_plugins = router,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2

vi /etc/neutron/neutron_lbaas.conf
[service_providers]
service_provider = LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

vi /etc/neutron/lbaas_agent.ini
[DEFAULT]
device_driver = neutron_lbaas.drivers.haproxy.namespace_driver.HaproxyNSDriver
interface_driver = linuxbridge
[haproxy]
user_group = haproxy

systemctl restart neutron-server

computer节点配置

yum install openstack-neutron-lbaas haproxy -y
同样是修改下面的文件
vi /etc/neutron/neutron.conf
service_plugins = router,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2

vi /etc/neutron/neutron_lbaas.conf
[service_providers]
service_provider = LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

vi /etc/neutron/lbaas_agent.ini
[DEFAULT]
device_driver = neutron_lbaas.drivers.haproxy.namespace_driver.HaproxyNSDriver
interface_driver = linuxbridge
[haproxy]
user_group = haproxy

systemctl enable neutron-lbaasv2-agent
systemctl start neutron-lbaasv2-agent

dashboard 开启lbaas

git clone https://git.openstack.org/openstack/neutron-lbaas-dashboard
cd neutron-lbaas-dashboard
git checkout stable/rocky
python setup.py install
cp neutron_lbaas_dashboard/enabled/_1481_project_ng_loadbalancersv2_panel.py /usr/share/openstack-dashboard/openstack_dashboard/local/enabled/

vi /etc/openstack-dashboard/local_settings
OPENSTACK_NEUTRON_NETWORK 中添加 ‘enable_lb’: True,

安装模块pip install neutron-lbaas-dashboard
不安装模块重启时日志会提示找不到模块，无法启用load balance

systemctl restart httpd
在项目，网络，有load balance

创建load balance后无法ping通，需要设置安全组
neutron lbaas-loadbalancer-show lbaas_name
neutron port-update –security-group security-group-name vip-port-id
安全组开放80和443端口
