openstack openstack-nova-consoleauth.service 和openstack-nova-scheduler.service 服务启动报错_unit openstack-nova-scheduler.service has failed

安装到nova 组件时，启动服务，发现nova-consoleauth、nova-scheduler 两个服务总是在启动中，

查看log 发现报错如下

## 是rabbitmq 的问题，无法访问

检查rabbitmq

rabbitmqctl list_users
Listing users ...
guest    [administrator]

明明创建了openstack用户，怎么没有

重新创建 openstack用户

rabbitmqctl add_user openstack RABBIT_PASS
Creating user "openstack" ...
rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/" ...

##检查一下是否创建成功

rabbitmqctl list_users

Listing user....
openstack    []
guest    [administrator]

###重启驱动rabbitmq-server 和nova服务的组件，显示正常，log 也显示成功访问amqp
