检查计算节点nova.conf文件my_ip是否写对：
; u) @0 Z# d/ ~  my_ip = 本地ip地址
$ I* e" f1 |7 I7 @5 L0 W  p
& s8 \; M" y* r  O; d* N, j写成本地IP地址，就不再报错。

怎么都不显示，以为自己的配置有问题，从头到尾的再弄了一遍，还是这个问题，看到原始文档，发现有个说：

Note: If the nova-compute service fails to start, check /var/log/nova/nova-compute.log. The error messageAMQP server on controller:5672 is unreachable likelyindicatesthatthefirewallonthecontroller node is preventing access to port 5672. Configure the firewall to open port 5672 on the controller node and restart nova-compute service on the compute node.

修改计算节点的配置之后，发现 openstack hypervisor list 获取到结果了。

问题总算解决了 ，获取到结果已经很不错了，compute.log日志也不在报错了。
