CentOS 7部署OpenStack--创建第一台虚拟机
郝朝阳 DevOps视角
创建key
[root@controller ~]# source kevin-openrc.sh[root@controller ~]# ssh-keygen -q -N ""[root@controller ~]# nova keypair-add --pub-key .ssh/id_rsa.pub mykey[root@controller ~]# nova keypair-list+-------+-------------------------------------------------+| Name | Fingerprint |+-------+-------------------------------------------------+| mykey | e8:8e:1f:33:d2:75:b6:32:bd:7d:68:aa:a1:f6:d5:fe |+-------+-------------------------------------------------+创建安全组
