按openstack官網安裝指南安裝nova,一切順利，無報錯出現，但是在驗證過程中出現不一致的輸出。

我的輸出（與安裝指南不一致的地方）：

1.將計算節點新增到cell資料庫（add the compute node to the cell database）

# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.
Getting compute nodes from cell 'cell1': ad5a5985-a719-4567-98d8-8d148aaae4bc
Found 0 unmapped coumputes in cell: ad5a5985-a719-4567-98d8-8d148aaae4bc
 

正常應該是：Found 1 compute in cell ....

此時察看計算節點的日誌：vim /var/log/nova/nova-computer.log

顯示：Placement API service is not responding 

察看控制節點的日誌：vim /var/log/nova/nova-placement-api.log

無錯誤顯示

2. 驗證（verify operation）

openstack compute service list

輸出為空

3. 

$ openstack catalog list

輸出正常

4. nova-status upgrade check 

輸出不一致

# nova-status upgrade check

+---------------------------+
| Upgrade Check Results     |
+---------------------------+
| Check: Cells v2           |
| Result: Success           |
| Details: None             |
+---------------------------+
| Check: Placement API      |
| Result: Success           |
| Details: None             |
+---------------------------+
| Check: Resource Providers |
| Result: Warning           |
| 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.             |

哪位大佬知道情指教，已經卡住好久了。。。
