解决Openstack部署过程openstack catalog list报错： Details: There are no compute resource providers in the Placement |  
| service but there are 1 compute nodes in the deployment. |  
| This means no compute nodes are reporting into the |  
| Placement service and need to be upgraded and/or fixed. |  
| See |  
| http://docs.openstack.org/developer/nova/placement.html |  
| for more details.

按openstack官网安装指南安装和配置计算节点,一切顺利，无报错出现，但是在验证过程中出现不一致的输出。

输入nova-status upgrade check命令检查单元格和放置API是否工作成功:  
输出（与安装指南不一致的地方）：

## 解决： ##

经检查发现是计算节点的/etc/nova/nova.conf文件中\[placement\]部分配置错误的原因，如下图，os\_region\_name配置重复，注释下面的一个配置后保存

**具体情况需自行检查配置是否有误！**

修改配置后重启nova-compute服务：

service nova-compute status

之后再次在控制节点验证，输出如下，成功解决
