使用OpenStack虚机启动的网卡是临时的,虚拟机重启就失效了,虚拟机挂起也会失效,网卡重启也会失效

The net that was activated with OpenStack is temporary, the virtual reboot lapses, the virtual hang-up lapses, and the reboot fails.

测试环境: 分别在三台机器上增加一个网卡，选择lan网段，地址172.16.0.0/24

Test environment: Add a net card to each of the three machines and select the lan section, address 172.1.0.0/24

（一）增加一个flat网络原因

(i) Reason for adding a flat network

（二）添加网卡eth1

(ii) Add Netcaeth1

控制节点:

互相进行ping测试,测试连通性

Test each other for ping, test for connectivity.

（三）控制节点配置
1:控制节点

(iii) Control Node Configuration
1: Control Node

c：重启
systemctl restart neutron-server.service neutron-linuxbridge-agent.service

c: restart reboot neutron-server.service neutron-linuxbridge-agent.service

（四）计算节点配置
a:

(iv) Calculate node configuration
a:

b：重启

b: Restart

（五）创建网络
1、命令行创建：
neutron net-create --shared --provider:physical_network net172_16_0
--provider:network_type flat jiage

(v) Creation of network
1 with command line creation:
neutron net-create-shared-provider:physical_network net172_16_0br> --provider:network_type flatjiage

neutron subnet-create --name jiage
--allocation-pool start=172.16.0.1,end=172.16.0.250
--dns-nameserver 223.5.5.5 --gateway 172.16.0.254
jiage 172.16.0.0/24

2、web页面创建网络：
管理员-网络-创建网络（供应商:平面）

2. Web page creation network:
Administrator-network-creation network (supplier: plane)

创建子网

Create Subnet

创建实例测试网络是否可用：项目-实例-创建实例（创建过程中可以选择刚创建的网络）

Create example test network availability: project - example - create example (the creation process allows for the selection of a network that has just been created)

目前网络内网是通的,但是外网不通.因为指定的网关真实并不存在
需要创建一个linux系统作为路由器使用：

The network is currently accessible, but the outer network is not. Because the designated gateway does not exist
requires the creation of a linux system to be used as a router:
