AMQP服务器控制器：5672关闭连接

5672是rabbitmq的端口，遇到这种情况仔细检查配置文件nova.conf下的[oslo_messaging_rabbit]配置

检查密码是否有误，如果不能确定密码就直接卸载rabbitmq-server重新安装

先卸载

yum remove rabbitmq-server

安装
yum install rabbitmq-server

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

添加用户
[root@compute ~]# rabbitmqctl add_user openstack 123456  
Creating user "openstack" ......done.

设置权限
[root@compute ~]# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/" ......done.
