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作为主节点，将node2作为其从节点。我将主节点的.erlang.cookie内容复制到从节点。尝试制作集群但出现了nodedown错误消息。

然而，作为此前讨论过的故障排除的一部分，我杀了兔子进程。

停止了rabbitmq经纪人，试图启动经纪人但不能。发布＆＃34; systemctl启动rabbitmq-server.service＆＃34; 然后发行＆＃34; journalctl -xe＆＃34;有关错误的更多详细信息

错误讯息：

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

％此文件由Puppet管理

％模板路径：rabbitmq / templates / rabbitmq.config

[

{兔，

[{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}]},

我从root用户退出了。再次登录.. 现在减少节点错误..

停止节点rabbit @ vmrabbitmqt02 ...

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

诊断

试图联系：[rabbit @ vmrabbitmqt02]

兔@ 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设置正确吗？
建议：是使用TLS的Erlang发行版吗？

当前节点详细信息：

节点名称：'rabbitmq-cli-90 @ vmrabbitmqt02'
home dir：/ var / lib / rabbitmq
cookie hash：xy56ebUJo + 5exKrQIexXrg ==

在erlang cookie更改后无法启动RabbitMQ节点
