Rabbitmqctl命令抛出错误

Question

我正在尝试在RabbitMQ上创建一个3节点集群。我有第一个节点启动并运行。当我从节点2发出join cluster命令时，它会抛出节点已关闭的错误。

rabbitmqctl join_cluster rabbit@hostname02

我收到以下错误：

Status of node rabbit@hostname02 ...
Error: unable to connect to node rabbit@hostname02: nodedown

DIAGNOSTICS
===========

attempted to contact: [rabbit@hostname02]

rabbit@hostname02:
  * connected to epmd (port 4369) on hostname02
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on hostname02
  * suggestion: start the node

current node details:
- node name: 'rabbitmq-cli-30@hostname02'
- home dir: /var/lib/rabbitmq
- cookie hash: bygafwoj/ISgb3yKej1pEg==

这是我的配置文件。

    {cluster_nodes, {[rabbit@hostname01, rabbitmq@hostname02, rabbit@hostname03], disc}},

我已使用所有3台服务器上所有3个节点的详细信息更新了/etc/hosts文件。我不确定我在哪里弄错了。
