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

检查计算节点nova.conf文件my_ip是否写对：
  my_ip = 本地ip地址

写成本地IP地址，就不再报错。

   这个地方有些不完美，我明明写了hosts域名解析了，为什么不解析呢？

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

# K1 s' D' b7 A, E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.

  O' G1 C7 N7 ?4 Y7 R5 A以为是nova里的配置文件中有rabbitmq配置有问题，结果不是，发现是compute的这个域名不能解析，bug不合理的地方。控制节点都没有问题的，不知道怎么解释。


- o. Y4 ^% z' r+ r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。
