突然有一天使用 nova list  出現錯誤了


[email protected]:~# nova list

ERROR:HTTPConnectionPool(host=‘openstackcloud1‘, port=35357):Max retries exceededwith url:/v2.0/tokens(Causedby<class‘socket.error‘>:[Errno111]Connection refused)

原因是  nova-api service   沒有啟動起來

結果啟動 還失敗了


# service openstack-nova-api restart
Redirecting to /bin/systemctl restart  openstack-nova-api.service
Job for openstack-nova-api.service failed. See ‘systemctl status openstack-nova-api.service‘ and ‘journalctl -xn‘ for details.

通過查詢錯誤記錄檔 /var/log/nova/nova-api.log


看到例如以下錯誤：


2015-07-21 04:11:30.800 6879 ERROR nova.wsgi [-] Could not bind to 0.0.0.0:8775

原因是

openstack-nova-api and openstack-nova-metadata-api both run on the same port so you are getting "Address already in use" error.Try stopping "openstack-nova-metadata-api" service and run "openstack-nova-api".

僅僅需兩步

# service openstack-nova-metadata-api stop


# service openstack-nova-api restart

成功了


[[email protected] Desktop]# service openstack-nova-metadata-api stop
Redirecting to /bin/systemctl stop  openstack-nova-metadata-api.service
[[email protected] Desktop]# service openstack-nova-api restart
Redirecting to /bin/systemctl restart  openstack-nova-api.service
