erlang cookie更改后无法启动RabbitMQ节点

Question

我是 RabbitMQ 的新手。尝试在 RHEL 7 服务器上创建 3 个节点的集群。需要将node3设为master，node1、node2设为slave。我将主节点的 .erlang.cookie 内容复制到从节点。尝试创建集群，但出现 nodedown 错误消息。

但是，作为前面讨论的故障排除的一部分，我杀死了 rabbit 进程。

停止 rabbitmq 代理，尝试启动代理但不能。 发出“systemctl start rabbitmq-server.service” 进而 发布“journalctl -xe”以获取有关错误的更多详细信息

错误信息：

Snapshot of rabbitmq-env.conf file along with details of hosts 请尽早提出一些措施。

使用的配置文件：

[root@vmrabbitmqt02 rabbitmq]# cat rabbitmq.config
% This file managed by Puppet
% Template Path: rabbitmq/templates/rabbitmq.config
[
{rabbit,
[{cluster_nodes, {['rabbit@vmrabbitmqt01', 'rabbit@vmrabbitmqt02', 'rabbit@vmrabbitmqt03'], disc}},
{cluster_partition_handling, ignore},
{ssl_listeners, [5671]},
{ssl_options, [{cacertfile,"/etc/rabbitmq/ssl/rabbitmq_wildcard_root_ca.crt"},
                {certfile,"/etc/rabbitmq/ssl/rabbitmq_wildcard.crt"},
                {keyfile,"/etc/rabbitmq/ssl/rabbitmq_wildcard.key"},
                {verify,verify_none},
                {fail_if_no_peer_cert,false}]},
{default_user, <<"guest">>},
{default_pass, <<"guest">>}
]}
].

我退出了 root 用户。 又登录了。。 现在出现节点关闭错误..

停止节点rabbit@vmrabbitmqt02 ...

错误：无法连接到节点rabbit@vmrabbitmqt02：nodedown

诊断

尝试联系：[rabbit@vmrabbitmqt02]

兔子@vmrabbitmqt02：

• 连接到 vmrabbitmqt02 上的 epmd（端口 4369）

• epmd 报告节点 'rabbit' 在端口 25672 上运行

• TCP 连接成功但 Erlang 分发失败

• 建议：主机名不匹配？

• 建议：cookie设置是否正确？

• 建议：Erlang 发行版是否使用 TLS？

当前节点详情：

• 节点名称：'rabbitmq-cli-90@vmrabbitmqt02'

• 主目录：/var/lib/rabbitmq

• cookie 哈希：xy56ebUJo+5exKrQIexXrg==
