执行

$ nova resize instance1

 

时候出错：

{
   "message": "Proxy error: 502 Read from server failed: Timeout.: 502 Read from server failed: Timeout: The following error occurred while trying to access http://172.16.13.140:9292/v1/images/bca45fe3-9f30-423e-ac74-80d98ef0a50e:: Generated Fri, 06 Jan 2017 11:00:44 HK", "code": 500, "details": "  File \"/opt/stack/nova/nova/compute/manager.py\", line 375, in decorated_function

 

解决方法：

到instance1所在的server上，执行

$screen -x stack

然后进入n－cpu服务：

$ unset http_proxy$ unset https_proxy$ unset no_proxy

 

就OK了
