    猜想肯定是neutron的错误,查询neutron状态,果然没有起,手动启动也报错

  2. 查询neutron日志 /var/log/neutron/server.log 有如下错误:

2015-05-25 10:09:08.489 7123 ERROR oslo_messaging._drivers.impl_rabbit [-] AMQP server on 172.16.37.211:5672 is unreachable: [Errno 111] ECONNREFUSED. Trying again in 1 seconds.

  2. 搜索关键字:Error: unable to connect to node rabbit@localhost: nodedown,找到如下解决方式

# systemctl enable rabbitmq-server.service
# systemctl start rabbitmq-server.service
# rabbitmqctl start_app

成功启动rabbitmq

  1. 启动neutrou-server,openstack恢复正常
# systemctl start neutron-server.service
