RabbitMQ localhost management failed to launch，日志文件中出现端口5672

Question

我在Windows 10机器上安装了RabbitMQ 3.11.2和Erlang 25.1.1。

我对RabbitMQ非常陌生，我无法启动RabbitMQ管理门户。我还启用了RabbitMQ管理插件。

在互联网上搜索了Stack Overflow, Google Groups和其他论坛上的各种建议，但都失败了。

在日志文件中，我发现了很多错误，如下所示:

我已经禁用了McAfee防火墙，我已经在McAfee防火墙中添加了5672端口，重新安装了RabbitMQ和Erlang应用程序至少10次，在windows防火墙安全中打开了5672端口，也尝试了docker镜像，但我的3天努力未能启动它。

我在这里附上了RabbitMQ和Erlang的日志文件，请提供宝贵的建议。

Answer 1

错误提示:

exception exit: {listen_error,{acceptor,{0,0,0,0,0,0,0,0},5672},eacces}

来自Erlang文档:https://www.erlang.org/doc/man/file.html

eacces
Missing search or write permissions for the parent directories of Dir.

Answer 2

对于看到此问题的其他人来说，根本原因是另一个使用TCP端口5672的进程-
