nova-compute.log錯誤日志一直報錯AMQP server controller:5672 closed the connection. 

AMQP伺服器控制器：5672關閉連接配接

5672是rabbitmq的端口，遇到這種情況仔細檢查配置檔案nova.conf下的[oslo_messaging_rabbit]配置

檢查密碼是否有誤，如果不能确定密碼就直接解除安裝rabbitmq-server重新安裝

先解除安裝

yum remove rabbitmq-server
           

安裝
yum install rabbitmq-server

啟動
systemctl enable rabbitmq-server.service  
systemctl start rabbitmq-server.service

添加使用者
[[email protected] ~]# rabbitmqctl add_user openstack 123456  
Creating user "openstack" ......done.

設定權限
[[email protected] ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/" ......done.
