openstack 虚拟机实例迁移

 

10.20.1.181    nova-api  controller

10.20.1.182　nova-compute    compute1

10.20.1.183  nova-compute　　compute2

 

实例迁移，需要nova用户在nova-compute 免密钥互通

10.20.1.182 上操作
修改成bash登录
[root@compute1 ~]# usermod -s /bin/bash nova
[root@compute1 ~]# passwd nova
[root@compute1 ~]# su - nova
-bash-4.2$  ssh-keygen -t rsa
-bash-4.2$  ssh-copy-id  nova@10.20.1.182

-bash-4.2$  ssh-copy-id  nova@10.20.1.183

10.20.1.183 上操作
修改成bash登录
[root@compute2 ~]# usermod -s /bin/bash nova
[root@compute2 ~]# passwd nova
[root@compute2 ~]# su - nova
-bash-4.2$  ssh-keygen -t rsa
-bash-4.2$  ssh-copy-id  nova@10.20.1.182

-bash-4.2$  ssh-copy-id  nova@10.20.1.183
