创建openstack初始网络

（1）network节点创建外部网络，controller节点执行如下命令

[root@controller ~]#source admin-openrc.sh

[root@controller ~]#neutron net-createext-net --router:external --provider:physical_network external--provider:network_type flat

[root@controller ~]#neutron subnet-createext-net 192.168.119.0/24 --name ext-subnet --allocation-poolstart=192.168.119.101,end=192.168.119.200

--disable-dhcp --gateway192.168.119.5(模拟外网网关）

（2）创建租户网络，在controller节点执行：

[root@controller ~]#source demo-openrc.sh

[root@controller ~]#neutron net-createdemo-net

[root@controller ~]#neutron subnet-createdemo-net 1.1.1.0/24 --name demo-subnet --dns-nameserver 8.8.4.4 --gateway1.1.1.1

（3）network节点创建vRouter,在controller节点执行：

[root@controller ~]#neutron router-createdemo-router

[root@controller ~]#neutronrouter-interface-add demo-router demo-subnet

[root@controller ~]#neutronrouter-gateway-set demo-router ext-net

（4）验证

controller节点重新绑定一个192.168.119.0/24网段的网卡，可以ping通bx-ex上分配的subnet网段的ip

[root@controller ~]# ping 192.168.119.101

PING 192.168.119.101 (192.168.119.101)56(84) bytes of data.

DASHBOARD

目前安装dashboard的时候可能出现包兼容的问题，鉴于可用CLI进行操作验证，暂且PASS

LAUNCH INSTANCE

注：centos7如果采用qemu作为libvirt的启动的方式，需要关注qemu的版本，默认qemu-1.5.3可能导致instance无法启动的

解决方案：升级qemu到2.5以上：yuminstall -y centos-release-qemu-ev yum-y install xxxx

[root@controller ~]#source demo-openrc.sh

[root@controller ~]#nova keypair-adddemo-key

[root@controller ~]#nova keypair-list

[root@controller ~]#nova flavor-list

[root@controller ~]# nova image-list

[root@controller ~]# neutron net-list

[root@controller ~]#nova boot --flavorm1.tiny --image cirros-0.3.4-x86_64 --nic net-id=0f5f9a16-4133-4876-a5e6-251e30b257d7--security-group default --key-name demo-key demo-instance1

[root@controller ~]#nova list

[root@controller ~]# nova get-vnc-consoledemo-instance2 novnc

验证：

Ping网关

Ping floating IP

Ping vDHCP Server IP

注：这边遇到个问题是running的镜像无法获取vDHCP分配过来的IP地址；经过排查，是VM发给network节点的dhcp消息被network节点的iptables规则给拒绝掉了，iptables规则不明白是怎么出现的，后面的同学可以借鉴
