[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# ssh-keygen -q -N ""
[root@linux-node1 ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey
[root@linux-node1 ~]# openstack keypair list
添加安全组规则
[root@linux-node1 ~]# openstack security group rule create --proto icmp default
[root@linux-node1 ~]# openstack security group rule create --proto tcp --dst-port 22 default
启动实例
[root@linux-node1 ~]# source demo-openstack.sh
[root@linux-node1 ~]# openstack flavor list
1.查看可用的镜像
[root@linux-node1 ~]# openstack image list

4.创建虚拟机
[root@linux-node1 ~]# openstack server create --flavor m1.nano --image a621e740-22a4-458f-b532-92bf0caf6ef9 --nic net-id=a52fba78-4fd6-452d-a596-e2e8827ccbc5 --security-group default --key-name mykey demo-instance

注意，这是通过network来创建虚机，若是要通过port来创建虚机，对应的就是 --nic port-id=port-uuid
