ERROR (ConnectionError): HTTPConnectionPool (Caused by <class 'socket.error'>: [Errno 111] Connecti

突然有一天使用 nova list 出现错误了

[email protected]:~# nova list

ERROR: HTTPConnectionPool(host=‘openstackcloud1‘, port=35357): Max retries exceeded with url: /v2.0/tokens (Caused by <class ‘socket.error‘>: [Errno 111] Connection refused)

原因是 nova-api service 没有启动起来

结果启动还失败了

# 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.
通过查询错误日志 /var/log/nova/nova-api.log

看到如下错误：

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".

只需两步

# 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

Delphi 通信报Asynchronous socket error 10053错误的一个解决方法

在使用Delphi中的TClientSocket和TServerSocket进行通信编程时,当使用TClientSocket这方的客户端使用TClientSocket.close断开连接并退出程序时,使用TServerSocket这方的服务端有时会报‘’Asynchronous socket error 10053‘这个错误,查阅了这个错误说明:Software caused connection abort.(因软件原因导致连接终止).这个原因说明很鸡肋,因为你还是无法确定到底是哪个地方出现了
