如何使用oslo_消息作为RabbitMQ的客户端负载平衡器

我有一个由3个节点组成的rabbitmq集群

root@47704165d2bb:/# rabbitmqctl cluster_status
Cluster status of node rabbit@47704165d2bb ...
[{nodes,[{disc,[rabbit@0482398a286e,rabbit@3709521b608a,
            rabbit@47704165d2bb]}]},
 {running_nodes,    [rabbit@0482398a286e,rabbit@3709521b608a,rabbit@47704165d2bb]},
 {cluster_name,<<"rabbit@47704165d2bb">>},
 {partitions,[]},
 {alarms,[{rabbit@0482398a286e,[]},
          {rabbit@3709521b608a,[]},
          {rabbit@47704165d2bb,[]}]}]
root@47704165d2bb:/# rabbitmqctl list_policies      
Listing policies ...
/       ha-all  all     ^ha\\.  {"ha-mode":"all"}       0

当我在一个节点上运行“service rabbitmq server stop”以模拟故障时，我得到了以下错误日志，并且使用者无法从坏节点进行故障切换。它将永远重新连接故障节点，而不是其他节点。“kombu_故障切换_策略”是“循环”的默认值

有人能帮我吗？谢谢
