如何在Windows上配置RabbitMQ集群

Question

拜托，我需要你的帮助。

自上周以来，我一直在努力尝试在Windows服务器上配置兔子MQ集群。我重新安装了 RabbitMQ 3.7.8 和 ErlangOTP 21-1 超过 15 次，试图找出问题并修复它，但不幸的是，我所有的尝试都失败了。

我的环境： 三个虚拟机与操作系统： Windows 服务器 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 

完成以上服务器的安装后，我开始配置集群

> < li >首先，我通过pinging Rabbit @ masternode验证了masternode可从RabbitMQ02，02到达，并且成功。 < li>

使用以下命令停止RabbitMQ服务器和应用程序

rabbitmq服务停止rabbitmqctl stop_app

启动RabbitMQ服务

rabbitmqctl start_app rabbitm2服务启动

一旦我达到这一点，我就会在RabbitMQ02上看到下面的错误。

C：\程序文件\RabbitMQ服务器\rabbitmq_server-3.7.8\sbin

最常见的原因是:

• 目标节点无法访问（例如，由于主机名解析、TCP 连接或 r 防火墙问题）
• CLI 工具无法与服务器进行身份验证（例如，由于 CLI 工具的 Erlang cookie 与服务器的 cookie 不匹配）
• 目标节点未运行

除以下诊断信息外：

• 请参阅有关 http://rabbitmq.com/document 的 CLI、群集和网络指南.html以了解更多信息
• 查阅节点rabbit@rhrabbitmq02上的服务器日志

试图联系:[rabbit@rhrabbitmq02]

rabbit@rhrabbitmq02: *连接到rhrabbitmq02 *上的epmd(端口4369)epmd报告节点“rabbit”使用端口25672进行节点间和CLI工具traff ic * 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：\用户\admin*Erlang cookie哈希：pndBksvQokXyiSqBdnne/g==

主节点状态：

Answer 1

问题解决方案:将RABBITMQ_NODENAME错误地设置为“masternode”而不是“rabbit@masternode”，命令执行序列中错误地执行了至关重要的事情(加入集群时-先停止_app，然后停止服务)，并且在更改配置后重新启动服务，而不是重新安装RABBITMQ服务。

如果需要根据我的设置场景在windows上安装、配置Rabbitmq和配置集群，我很乐意分享所有步骤的详细信息。最好的问候。
