11.5 生成一个键值对
[root@node-251 openstack]# openstack keypair create --public-key ~/.ssh/id_rsa.pub mykey

| user_id | 063ef7b979334fa5a86420952a141d32 |
+-------------+-------------------------------------------------+
验证公钥的添加
[root@node-251 openstack]# openstack keypair list
+-------+-------------------------------------------------+
| Name | Fingerprint |
+-------+-------------------------------------------------+
| mykey | 7c:b8:ca:bf:1f:fa:e1:6c:53:14:03:8d:3e:5e:26:b2 |
+-------+-------------------------------------------------+
如果没有密钥，可自行添加
ssh-keygen -q -N ""
11.6 增加安全组规则
默认情况下，default安全组适用于所有实例并且包括拒绝远程访问实例的防火墙规则。对诸如CirrOS这样的Linux镜像，我们推荐至少允许ICMP (ping) 和安全shell(SSH)规则。
允许 ICMP (ping)：
[root@node-251 openstack]# openstack security group rule create --proto icmp default
+-------------------+--------------------------------------+
