server - RabbitMQ启动失败，TCP连接成功但Erlang分发失败

Question

我是一个刚开始在 Windows 系统上学习和安装 RabbitMQ 的新手。

我在自定义文件夹中安装 Erlang VM 和 RabbitMQ，而不是默认文件夹(两者)。

然后我重新启动了我的电脑。

顺便说一句，我的电脑名称是“NULL”

我cd到 RabbitMQ/sbin 文件夹和使用命令:
rabbitmqctl status
但是返回的信息是:

Status of node rabbit@NULL ...

Error: unable to perform an operation on node 'rabbit@NULL'. Please see diagnostics information and suggestions below.

Most common reasons for this are:

• Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
• CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
• Target node is not running

In addition to the diagnostics info below:

• See the CLI, clustering and networking guides on http://rabbitmq.com/documentation.html to learn more
• Consult server logs on node rabbit@NULL

DIAGNOSTICS

attempted to contact: [rabbit@NULL]

rabbit@NULL:

• connected to epmd (port 4369) on NULL
• epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic

• TCP connection succeeded but Erlang distribution failed

• Authentication failed (rejected by the remote node), please check the Erlang cookie

Current node details:

• node name: rabbitmqcli70@NULL
• effective user's home directory: C:\Users\Jerry Song
• Erlang cookie hash: 51gvGHZpn0gIK86cfiS7vp==

我尝试重新启动RabbitMQ，我得到的是:

ERROR: node with name "rabbit" already running on "NULL"

By the way，My Computer name is "NULL" And I have enable all ports in firewall.

描述了在全新安装的 Rabbit MQ 上存在 cookie 不匹配的问题。 Windows 上的简单解决方案是同步 cookie

此处也有描述:http://www.rabbitmq.com/clustering.html#erlang-cookie

确保 cookie 在下面的 1、2 和可选 3 之间同步

%HOMEDRIVE%%HOMEPATH%\.erlang.cookie (通常 C:\Users\%USERNAME%\.erlang.cookie 对于用户 %USERNAME%)如果同时设置了 HOMEDRIVE 和 HOMEPATH 环境变量

%USERPROFILE%\.erlang.cookie (通常 C:\Users\%USERNAME%\.erlang.cookie)如果 首页和 首页不是都设置了

对于 RabbitMQ Windows 服务 - %USERPROFILE%\.erlang.cookie (通常 C:\WINDOWS\system32\config\systemprofile)

Windows 服务帐户使用的 cookie 文件和运行 CLI 工具的用户必须通过从 C:\WINDOWS\system32\config\systemprofile 复制一个来同步。文件夹。
