安装openstack踩的一个坑
Openstack Mitaka在图形化界面的时候出现以下报错：
[root@linux-node1 ~]# openstack server create --flavor m1.tiny --image cirros --nic net-id=2d79dc77-be66-4850-af01-8e6946f16035 --security-group default --key-name mykey provider-instance Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible. <class ‘neutronclient.common.exceptions.Unauthorized‘> (HTTP 500) (Request-ID: req-1d4cf44f-8b06-43e0-8392-25296b29eecb)
查了下网上资料，各种奇葩版本都有，但是对我的这个问题没有任何效果，核查下配置文件：

按照报错提示，检查我的nova配置，检查控制节点和计算节点，也没发现有啥异常
grep ‘ERROR‘ /var/log/nova/* grep ‘ERROR‘ /var/log/neutron/* grep ‘ERROR‘ /var/log/glance/* grep ‘ERROR‘ /var/log/keystone/*
后来排查发现（自己在编辑neutron的时候，忘记添加rpc_backend = rabbit）：
在计算节点后控制节点都添加后，重启neutron相关服务，然后再次执行创建云主机的操作

到此，问题得到解决，OpenStack的配置是个细心活，需要明白它的各个组件的关联，这样排除故障的时候会有的放矢。
