我今天有重新做了一次，重启了neutron服务，正常，但一创建网络后查看L3-agent的日志还是有个警告。

网络这块是很多人的难题，毕竟网络工程师，不会做开发的事情，而开发和部署在做网络的事情。

这里分享 ...

按照上面的方法，重启了neurton服务，l3-agent没有出现同样的错误日志。

不过还是有一点想问，我这种问题应该从哪方便去查找。
因为我实际需求就是我现在的这种模型。

两台双网卡的服务器，在服务器上搭建openstack基础平台，后面还会有 Heat、Ceilometer、Sahara。

最新情况是又加了个SDN，SDN上面要求把DHCP，L3放到compute上。想想都头疼

根据openstack icehouse安装文档openstack-install-guide-yum-icehouse.pdf, 安装部署进行到第66页时,已经部署好了controller和network的.

过程中没有报错.但是,在network node上查看日志时,发现/var/log/neutron/dhcp-agent.log中报错:
Remote error: AgentNotFoundByTypeHost Agent with agent_type=DHCP agent and host=network-node could not be found.


解决方法: 更改三个服务之间的启动顺序先后为openvswitch,dhcp,l3.且每个服务启动后间隔10s钟.
下面是icehouse文档中的内容
2. Start the Networking services and configure them to start when the system boots:
# service neutron-openvswitch-agent start
# service neutron-l3-agent start
# service neutron-dhcp-agent start
# service neutron-metadata-agent start

下面是更改后的安装脚本中的内容:

service neutron-openvswitch-agent start
sleep 10
service neutron-dhcp-agent start
sleep 10
service neutron-l3-agent start
sleep 10
service neutron-metadata-agent start
