ERROR oslo_service.service AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN

在 openstack 中部署 cinder 服务，发现服务无法正常启动

查看日志发现报错信息如下:

ERROR oslo_service.service AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN

 

发现问题在于 rabbitmq

查看 rabbitmq 用户，之前创建的 openstack 用户消失了

 

尝试重新创建 openstack 用户

rabbitmqctl add_user openstack RABBIT_PASS
rabbitmqctl set_permissions openstack ".*" ".*" ".*"

[root@controller ~]# rabbitmqctl list_users
Listing users
openstack    []
guest    [administrator]

重新启动 cinder 相关服务

systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl restart openstack-cinder-volume.service target.service
