说明：这里的公网，实际上是虚拟机用的那个网段，我们暂时把它作为公网，在这里因为涉及到dhcp服务，会和局域网内的路由器上的dhcp服务产生冲突，所以需要先把路由器上的dhcp服务关掉。
运行实例 - 创建key 【控制节点】
执行初始化脚本
source demo-openrc.sh
生成密钥
ssh-keygen -q -N ""
nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey
[[email protected] ~]# ssh-keygen -q -N "" Enter file in which to save the key (/root/.ssh/id_rsa): [[email protected] ~]# nova keypair-add --pub-key ~/.ssh/id_rsa.pub mykey [[email protected] ~]#
验证密钥
nova keypair-list
增加安全组规则
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
允许ssh 访问
