Question

请，我需要您的帮助。

自上周以来，我一直在尝试在Windows服务器上配置RabbitMQ群集。我重新安装了RabbitMQ 3.7.8和ErlangOTP 21-1超过15次，试图找出问题并解决，但不幸的是，我所有的尝试都失败了。

我的环境： 带有操作系统的三个虚拟机：Windows Server 2012

环境变量设置：

•   ERLANG_HOME = C:\Program Files\erl10.1
•   path: C:\Program Files\Handle
•   %RABBITMQ_BASE% = c:\RabbitMQ
•   %RABBITMQ_CONFIG_FILE% = %RABBITMQ_BASE%
•   RABBITMQ_NODENAME = masternode
•   Server names: RabbitMQ01 “masternode” , RabbitMQ02, RabbitMQ03
•   Adding IP & hots name “masternode” in the host file for name resolution (C:\Windows\System32\drivers\etc\hosts)
•   Setting RabbitMQ configuration file “advanced.config” in c:\users\USERNAME\AppData\Roaming\RabbitMQ” to enable users to login to RabbitMQ management remotely by adding the following setting
[
{rabbit,
  [
   {tcp_listeners, [5672]},
   {loopback_users, []},

   {num_tcp_acceptors, 100}
  ]
  }
].

安装步骤：（针对每台服务器）

1. After setting the environment variables, I restarted the machine. Then
2. Install ErlangOTP 21-1
3. Install RabbitMQ 3.7.8 server
4. Enable plugins - rabbitmq-plugins.bat enable rabbitmq_management

完成上述服务器的安装后，我开始配置集群

首先，我通过ping Rabbit @ masternode验证了RabbitMQ02，02可以访问masternode，并且成功。
使用以下命令停止RabbitMQ服务器和App

rabbitmq服务停止 rabbitmqctl stop_app
1. 将.erlang.cookie从主节点“ path = c：\ windows \ system32 \ config \ systemprofile”复制到RabbitMQ02“ path = c：\ windows \ system32 \ config \ systemprofile”和“ path = c：\ users \ USERNAME” ”。
通过执行以下命令启动RabbitMQ服务和应用

rabbitmqctl start_app rabbitmq-服务启动

通过执行此命令“ rabbitmqctl stop_app”再次停止应用
我开始将RabbitMQ02加入主节点 rabbitmqctl join_cluster rabbit@masternode（小写）

一旦达到这一点，我在RabbitMQ02上就会收到以下错误消息。

C：\ Program Files \ RabbitMQ Server \ rabbitmq_server-3.7.8 \ sbin> rabbitmqctl join_cluster rabbit @ masternode 错误：无法在节点“ rabbit @ rhrabbitmq02”上执行操作。请参阅诊断信息和建议如下。

最常见的原因是：

目标节点不可访问（例如，由于主机名解析，TCP连接o r防火墙问题）
CLI工具无法通过服务器进行身份验证（例如，由于CLI工具的Erlang） Cookie与服务器不匹配）
目标节点未运行

除了下面的诊断信息：

请参阅http://rabbitmq.com/document上的CLI，群集和联网指南 ation.html了解更多信息
咨询服务器登录节点Rabbit @ rhrabbitmq02

诊断

试图联系：[rabbit @ rhrabbitmq02]

rabbit @ rhrabbitmq02： *连接到rhrabbitmq02上的epmd（端口4369） * epmd报告节点“兔子”使用端口25672进行节点间和CLI工具流量我知道了 * TCP连接成功，但Erlang分发失败

身份验证失败（被远程节点拒绝），请检查Erlang Cookie

当前节点详细信息： *节点名称：rabbitmqcli41 @ rhrabbitmq02 *有效用户的主目录：C：\ Users \ admin * Erlang Cookie哈希：pndBksvQokXyiSqBdnne / g ==

Answer 1

问题解决方案：错误地将RABBITMQ_NODENAME设置为“ masternode”而不是“ rabbit @ masternode”，命令执行顺序中发生的错误是要执行的关键操作（在加入集群时-首先stop_app，然后服务停止），并在更改后重新启动服务配置，而不是重新安装rabbitmq服务。

如果愿意，可以根据我的设置场景在Windows上安装，配置Rabbitmq和配置群集，共享所有步骤的详细信息。最好的问候。
