neutron中lbaas的agent启动失败

按照以下步骤安装lbaas服务，dashboard可以看到lb的配置界面

1、 配置lbaas服务vi/etc/neutron/lbaas_agent.ini，添加红色的行

[DEFAULT]

output_file = etc/lbaas_agent.ini.sample

wrap_width = 79

namespace = neutron.lbaas.agent

namespace = oslo.log

interface_driver =neutron.agent.linux.interface.OVSInterfaceDriver

device_driver = neutron.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver

ovs_use_veth = True

[haproxy]

user_group = nobody

说明：interface_driver 的作用是设置 load balancer 的网络接口驱动，可以有两个选项：Linux Bridge和Open vSwitch。

2、 配置/etc/neutron/neutron_lbaas.conf，添加红色的行

[DEFAULT]

output_file = etc/neutron_lbaas.conf.sample

wrap_width = 79

namespace = neutron.lbaas

[service_providers]

service_provider =LOADBALANCER:Haproxy:neutron_lbaas.services.loadbalancer.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

说明：除了默认的 HAProxy，Neutron 也支持第三方 provider，比如 radware，VMWareEdge 等。

3、 数据库建表

neutron-db-manage--service lbaas upgrade head

4、  添加lbaas服务到neutron中

vi /etc/neutron/neutron.conf

………..

service_plugins = lbaas,onos_router,neutron.services.metering.metering_plugin.MeteringPlugin

…………

5、  dashboard启用服务

vi/usr/share/openstack-dashboard/openstack_dashboard/local/local_settings.py

………..

OPENSTACK_NEUTRON_NETWORK = {

   'enable_distributed_router': False,

   'enable_firewall': True,

   'enable_ha_router': False,

   'enable_lb': True,

   'enable_quotas': True,

   'enable_security_group': True,

   'enable_vpn': True,

   'profile_support': None,

}

………..

6、  重启neutron服务

service neutron-server stop

service neutron-serverstart

界面如下：

安装好了之后，无法创建资源池，查看日志报错如下：

无法手动启动，求大神帮忙看看

好像配置是有些出入。楼主参考下面
service_provider 在 /etc/neutron/neutron_lbaas.conf
device_driver 在 /etc/neutron/lbaas_agent.ini
service_plugins 在 /etc/neutron/neutron.conf


如果是 v1 plugin:
service_provider = LOADBALANCER:Haproxy:neutron_lbaas.services.loadbalancer.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default
device_driver = neutron.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver
service_plugins = lbaas

如果是v2 plugin:
service_provider = LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default
device_driver = neutron_lbaas.drivers.haproxy.namespace_driver.HaproxyNSDriver
service_plugins = lbaasv2(需要配置lbaasv2路径在 neutron的 entry_points.txt)

好像配置是有些出入。楼主参考下面

device_driver ...

我之前用的是V1的，后来改成V2试了也不行。不过配置好像和你不太一样
neutron_lbaas.conf上面配置
service_provider = LOADBALANCERV2:Haproxy:neutron_lbaas.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default
lbaas_agent.ini上面
device_driver = neutron_lbaas.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver

neutron.conf上面
service_plugins = firewall,vpnaas,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPluginv2,



我看我上面的log报错，有这个错误

2017-05-18 03:25:37.500 22470 WARNING neutron.services.provider_configuration [req-fd257665-d11a-47b9-b037-04158ac699c1 - - - - -] The configured driver neutron.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver has been moved, automatically using neutron_lbaas.services.loadbalancer.drivers.haproxy.namespace_driver.HaproxyNSDriver instead.

我先试下你的配置~~
