可以看到，nova-cert等组件已经down了～

解决办法：

cd /etc/rabbitmq/

vim rabbitmq.config

添加内容如下：

[rabbit,[{loopback_users,[]}]}].


然后，重启

service rabbitmq-server restart

结果如下：

root@controller2:/etc/rabbitmq# nova service-list
+----+------------------+-------------+----------+---------+-------+----------------------------+----------------
