你遇到的 RabbitMQ 启动失败错误是这个：
ERROR: could not bind to distribution port 25672, it is in use by another node: rabbit@BF-202405311136
错误分析
RabbitMQ 默认使用 端口 25672 做为 Erlang 分布式节点通讯端口。
这个报错表示：
-
端口 25672 已被占用，通常是 另一个 RabbitMQ 实例已经启动了，或者之前的进程没释放端口。
解决方法
方法一：杀掉已占用 25672 的 RabbitMQ 进程（推荐）
1、打开命令行，执行：
netstat -ano | findstr 25672
输出：
TCP 0.0.0.0:25672 0.0.0.0:0 LISTENING 12345
其中 12345 是 PID（进程号）。
2、查一下是什么进程
tasklist /FI “PID eq 12345”
3、如果确定是 RabbitMQ，结束它：
taskkill /PID 12345 /F
4、然后重新启动：
rabbitmq-server start
方法二：彻底重启 RabbitMQ 服务
rabbitmq-service stop
rabbitmq-service start
或
net stop rabbitmq
net start rabbitmq
运行以下命令看是否已在运行：
rabbitmqctl status
