neutron dhcp ha 实验

4个节点(controller, network,2 compute nodes)

1.0 on the network node

1.1

set –I ‘s/start] on/#start\ on/g’ /etc/init/neutron-dhcp-agent.conf

1.2 Stop dhcp agent”
service neutron-dhcpagent stop

2.0
on the compute node1

2.1
install the dhcp agent:
apt-get install neutron-dhcp-agent -y

2.2
mv /etc/neutron/dhcp_agent.ini /etc/neutron/dhcp_agent.ini.bk

2.3
拷贝网络节点的配置到计算节点node1
mv network:/etc/neutron/dhcp_agent.ini
/etc/neutron/dhcp_agent.ini.

2.4
启动node1上的dhcp agent
service neutron-dhcp-agent restart

3.0
On compute node 2

3.1
和node1一样，同样在node2上启动dhcp-agent

4.0
On the controller node

4.1
查看agent的状态：neutron agent-list

4.2
创建network
“private”和相应的subnet
neutron net-create private
neutron subnet-create –name private-subnet private 10.0.0.0/29

4.3
创建network
“private1”和相应的subnet
neutron net-create private1
neutron subnet-create –name private1-subnet private1 10.0.1.0/29

4.4
在private上启动一个instance，private1上启动2个instance
nova boot –image cirros-qcow2 –flavor 1 –nic net-id=<private net is>
private one

nova boot –image cirros-qcow2 –flavor 1 –nic
net-id=<private1 net is> private1 two

nova boot –image cirros-qcow2 –flavor 1 –nic
net-id=<private1 net is> private1 three

4.5
nova list

5.0
on node1 和node2

5.1
ip netns
可以看到network namespaces

6.0
on controller node

6.1
查找dhcp agent 的ID

6.2
查找那个dhcp agent 服务private 和private1
neutron dhcp-agent-list-hosting-net private
neutron dhcp-agent-list-hosting-net private1

6.3
或者查找private(1)上都有哪些dhcp agent

Neutron net-list-on-dhcp-agent <dhcp agent ID on
node1>

Neutron net-list-on-dhcp-agent <dhcp agent ID on node2>

6.4
检查2个dhcp agent

Neutron agent-show <dhcp agent ID on node1>

Neutron agent-show
<dhcp agent ID on node2>
可以看到neutron 会track每个agent的heartbeat信息

6.5 为每个网络private(1) 部署 DHCP HA(需要为每个network添加？)

Neutron dhcp-agent-network-add <dhcp agent ID on node2> private1

Neutron dhcp-agent-network-add <dhcp agent ID on node1> private2

6.6
验证每个网络都有2个agent

neutron dhcp-agent-list-hosting-net private
neutron dhcp-agent-list-hosting-net private1

6.7
log in instance3,通过node1(2)上的netns

ip netns exec <qdhcp-network id> ssh cirros@instance3

6.8
停掉node2 上的agent

Killall dnsmasq

Service neutron-dhcp-agent stop

6.9
用udhcpc验证instance3依然可以得到IP

ip netns exec <qdhcp-network id> ssh cirros@instance3

on instance3

sudo udhcpc

7.0
on controller and node1(2)

7.1 移除已经stop的node2上的agent

Neutron agent-delete <dhcp agent ID on node2>

7.2 验证node2上的agent不在

Neutron agent-list

7.3 重启node2上的agent

Service neutron-dhcp-agent restart

7.4 验证node2的agent又回来了

Neutron agent-list
