windows RabbitMQ 有 Nodedown 错误

RabbitMQ has Nodedown Error

提问by Brent Arias

On a Windows 7 Enterprise machine, I made a fresh install of Erlang 17.4 and RabbitMQ 3.4.3 x64. The installation was successful and uneventful.

在 Windows 7 Enterprise 机器上，我全新安装了 Erlang 17.4 和 RabbitMQ 3.4.3 x64。安装成功且顺利。

I have not yet tried to create my first queue or exchange, but I already see trouble. This problem is similar to another SO post, but that other post appears to involve clustering, which I don't have. Furthermore, that other poster can circumvent his issue by restarting the RabbitMQ service; that approach does not work for me.

我还没有尝试创建我的第一个队列或交换，但我已经看到了问题。这个问题类似于另一个 SO post，但另一个帖子似乎涉及聚类，而我没有。此外，其他发布者可以通过重新启动 RabbitMQ 服务来规避他的问题；这种方法对我不起作用。

My "nodedown" problem is evident at the RabbitMQ command prompt:

我的“nodedown”问题在 RabbitMQ 命令提示符下很明显：

C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.4.3\sbin>rabbitmqctl status Status of node rabbit@TPAJ05421843 ...
Error: unable to connect to node rabbit@TPAJ05421843: nodedown

Based on the above, I chose to check the status of the node explicitly named 'RabbitMQ'. I get this:

基于上述，我选择检查显式命名为“RabbitMQ”的节点的状态。我明白了：

C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.4.3\sbin>rabbitmqctl -n RabbitMQ status
Status of node 'RabbitMQ@TPAJ05421843' ...

RabbitMQ@TPAJ05421843:
* 连接到 TPAJ05421843 上的 epmd（端口 4369）
* epmd 报告在端口 59301 上运行的节点“RabbitMQ”
* 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？

当前节点详细信息：
- 节点名称：'rabbitmqctl-23076@TPAJ05421843'
- 主目录：H:\
- cookie 哈希：PD4QQCYrf0TME9vIko3Xuw==

Ok, this is barely better since at least it acknowledges 'RabbitMQ' running on port 59301. But what the heck could it mean that "Erlang distribution failed"?

好吧，这几乎没有好转，因为至少它承认“RabbitMQ”在端口 59301 上运行。但是“Erlang 分发失败”到底意味着什么？

When I try to research this topic, I found articles saying "be sure you have matched cookies." Based on that I found this article, which claims the "cookie mismatch" does not pertain to me, because I have not created (nor intend to create) a RabbitMQ cluster.

当我尝试研究这个主题时，我发现一些文章说“确保你有匹配的 cookie”。基于此，我发现了这篇文章，其中声称“cookie 不匹配”与我无关，因为我还没有创建（也不打算创建）RabbitMQ 集群。

What should I do?

我该怎么办？

I had this same problem today. There were no cookie or firewall problems and windows reported that the service was running successfully. This is what finally fixed it:

我今天遇到了同样的问题。没有 cookie 或防火墙问题，windows 报告服务运行成功。这是最终修复它的原因：

1. Run RabbitMQ sbin command prompt as administrator.
2. Run "rabbitmq-service remove"
3. Run "rabbitmq-service install"

1. 以管理员身份运行 RabbitMQ sbin 命令提示符。
2. 运行“rabbitmq-service remove”
3. 运行“rabbitmq-service install”

For some reason the service set up by the installer did not configure several registry entries. Running this set them correctly and allowed the service to run.

由于某种原因，安装程序设置的服务没有配置多个注册表项。运行此设置正确并允许服务运行。

One thing I noticed was that before I did this, there was no description of the service in the Windows Services view. After installing with the rabbitmq-service command, the description was visible. This might be a quick indicator if you are having the same problem.

我注意到的一件事是，在我执行此操作之前，Windows 服务视图中没有对该服务的描述。使用 rabbitmq-service 命令安装后，描述可见。如果您遇到同样的问题，这可能是一个快速指标。

As @eddyP commented, I had two different Erlang cookie files:

正如@eddyP 评论的那样，我有两个不同的 Erlang cookie 文件：

• A servercookie file, located at $env:WINDIR\system32\config\systemprofile\.erlang.cookie(prior to Erlang 20.2 it was located at $env:WINDIR\.erlang.cookie).
• A clientcookie file, located at $env:USERPROFILE\.erlang.cookie.

• 一个服务器cookie 文件，位于$env:WINDIR\system32\config\systemprofile\.erlang.cookie（在 Erlang 20.2 之前，它位于$env:WINDIR\.erlang.cookie）。
• 一个客户端的cookie文件，位于$env:USERPROFILE\.erlang.cookie。

Copying the server cookie file over the client one, so that both files were the same, fixed the problem for me.

将服务器 cookie 文件复制到客户端，使两个文件相同，为我解决了问题。

For further details, see "How Nodes (and CLI tools) Authenticate to Each Other: the Erlang Cookie".

The same question on the RabbitMQ mailing list: https://groups.google.com/forum/#!topic/rabbitmq-users/0s1ExFhl4hM.

RabbitMQ 邮件列表上的相同问题：https://groups.google.com/forum/#! topic/rabbitmq-users/0s1ExFhl4hM 。

The Erlang cookie is used by rabbitmqctlas well as server nodes, so it may need being taken care of (placed in the correct location). See "Installing as a non-administrator user leaves .erlang.cookie in the wrong place" on Windows quirks.

Erlang cookie 由rabbitmqctl服务器节点和服务器节点使用，因此可能需要对其进行处理（放置在正确的位置）。请参阅Windows quirks上的“以非管理员用户身份安装会将 .erlang.cookie 留在错误的位置” 。

If you come here looking for a linux answer for the same error message, try

如果您来这里寻找相同错误消息的 linux 答案，请尝试

sudo service rabbitmq-server start

(which is not a blocking command)

（这不是阻塞命令）

Just do the following:

只需执行以下操作：

1. Uninstall rabbitmq and erlang.
2. delete the rabbitmq folder existing in your appdata (if you dont know the appdata location, just type echo %AppData%in the command prompt)
3. Then install erlang first and then rabbitmq.

4. After installing, enable the management plugin using below command:

   rabbitmq-plugins enable rabbitmq_management

1. 卸载rabbitmq和erlang。
2. 删除 appdata 中存在的 rabbitmq 文件夹（如果您不知道 appdata 位置，只需在命令提示符中键入echo %AppData%）
3. 然后先安装erlang，再安装rabbitmq。

4. 安装后，使用以下命令启用管理插件：

   rabbitmq-plugins 启用 rabbitmq_management

For me the cookies didnt match, like the other comments but the locations was in a different path for those having the same issue as me C:\Windows\System32\config\systemprofile

对我来说，cookie 不匹配，就像其他评论一样，但对于那些与我有相同问题的人来说，位置在不同的路径中 C:\Windows\System32\config\systemprofile

That is happening because rabbit MQ is not being installed correctly on Windows (and this error is misleading!). So to solve it do the following:

发生这种情况是因为在 Windows 上未正确安装 rabbit MQ（并且此错误具有误导性！）。所以要解决它，请执行以下操作：

1. type "cmd" in Cortana search or in "Run" for older version of Windows
2. right click on in and choose "Run as Administrator"
3. go to rabbit's sbin folder (cd "C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin")
4. run: rabbitmq-service remove
5. run: rabbitmq-service install

1. 在 Cortana 搜索或旧版 Windows 的“运行”中输入“cmd”
2. 右键单击并选择“以管理员身份运行”
3. 转到 rabbit 的 sbin 文件夹（cd "C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin"）
4. 运行：rabbitmq-service remove
5. 运行：rabbitmq-service install

now you can run 6. rabbitmq-plugins enable rabbitmq_management 7. rabbitmq-service start 8. and, finally, run: start http://localhost:156729. log on as user "guest" with password: "guest" and that's it. Happy Rabbiting!

现在你可以运行 6. rabbitmq-plugins enable rabbitmq_management 7. rabbitmq-service start 8. 最后，运行：start http://localhost:156729. 以用户“guest”登录，密码：“guest”它。兔兔快乐！
