ERROR nova.compute.manager ValueError: failed to detect a valid IP address from 'compute'
遇到的完整报错如下：

这个my_ip理论来讲应该是写compute这个地址也是对的，可是偏偏报了一大堆的错误，实在难解释。

[root@controller ~]# openstack hypervisor list

[root@controller ~]# openstack hypervisor list

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：
0 [: v8 x3 o0 @
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。
