当我启动rabbitmq-server服务，执行命令 [root@VM-4-7-centos bin]# rabbitmq-server start，
就遇到报错，报错的解释是： 不能绑定分配端口25672， 它正在被其他节点使用。
我用的环境、版本等信息：
Linux： 腾讯云CentOS 8.0
erlang ： 23.3
rabbitmq ： 3.10.5
socat ： 1.7.4.1
解决办法：
1、查一下端口25672被谁占用了。
执行命令： lsof -i:25672
[root@VM-4-7-centos bin]#
[root@VM-4-7-centos bin]# lsof -i:25672
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
beam.smp 888747 rabbitmq 18u IPv4 4676158 0t0 TCP *:25672 (LISTEN)
[root@VM-4-7-centos bin]#
可以看出是被 rabbitmq的一个文件占用了，进程号： 888747
以为kill -9 888747，就可以了。
这样就陷入这个泥潭里了。
后来，
执行命令： [root@VM-4-7-centos bin]# rabbitmqctl stop
正在停止和停止节点rabbit@VM-4-7-centos
[root@VM-4-7-centos bin]#
[root@VM-4-7-centos bin]#
Stopping and halting node rabbit@VM-4-7-centos ...
[root@VM-4-7-centos bin]#
[root@VM-4-7-centos bin]#
rabbitmqctl stop 主要是解决停止应用和节点的作用。
再次执行命令 rabbitmq-server start，就不会报错了。
