九：OPENSTACK Queens创建云主机

Posted 2021-04-24 MisterChen

• 创建网络

[root@controller ~]# . admin_src 

[root@controller ~]# openstack network create  --share --external   --provider-physical-network provider   --provider-network-type flat provider

[root@controller ~]#openstack subnet create --network provider   --allocation-pool start=192.168.1.20,end=192.168.1.30 --dns-nameserver 202.96.209.133 --gateway 192.168.1.1 --subnet-range 192.168.1.0/24 provider

• 建一个实例类型1颗CPU，64M内存

[root@controller ~]# openstack flavor create --id 0 --vcpus 1 --ram 64 --disk 1 m1.nano

• 创建一个私有秘钥

[root@controller ~]# . demo_src 

[root@controller ~]# ssh-keygen -q -N ""

Enter file in which to save the key (/root/.ssh/id_rsa): 

[root@controller ~]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

• 增加一个可以允许icmp协议的组

[root@controller ~]# openstack security group rule create --proto icmp default

• 允许SSH

[root@controller ~]# openstack security group rule create --proto tcp --dst-port 22 default

• 创建一个虚拟机前，检查一下各个项目

[root@controller ~]# openstack flavor list

[root@controller ~]# openstack image list

[root@controller ~]# openstack network list

[root@controller ~]# openstack security group list

[root@controller ~]# openstack server create --flavor m1.nano --image cirros --nic net-id=PROVIDER_NET_ID --security-group default --key-name mykey cirros

备注：net-id换成自己的网络ID

[root@controller ~]# openstack server list

[root@controller ~]# openstack console url show cirros

如果使用的是ESXI虚拟机，一定要把网络的混杂模式打开
