我正在尝试安装rabbitmq。所以我面临的问题如下。为了安装，我使用这个博客

rabbitmq-server is already the newest version (3.8.7-1).
The following packages were automatically installed and are no longer required:
erlang-diameter erlang-edoc erlang-erl-docgen erlang-eunit erlang-ic erlang-inviso erlang-nox erlang-odbc erlang-percept erlang-ssh libodbc1 libsctp1
Use 'sudo apt autoremove' to remove them.

很多次我删除了rabbitmq的所有包并再次安装，但都没有成功。
我试着用下面的命令来解决这个问题，就像我从其他博客中得到的一样。
$ sudo apt-get update --fix-missing
$ sudo dpkg --configure -a
$ sudo apt-get install -f
$ sudo apt-get install rabbitmq-server -y --fix-missing
运行systemctl status rabbitmq-server.service后的日志

什么都没用。请帮忙。
提前谢谢。
问题很可能是rabbitmq试图使用的端口当前正被另一个进程使用。这在journalctl -xe的输出中说明
... : Error during startup: {error,{could_not_start_listener,"::",5672,eaddrinuse}}
您可以在带有的机器上看到当前正在使用的所有端口
$ lsof -i -P -n
或专门检查该端口
$ lsof -i -P -n|grep 5672
因此，您可以使用端口5672终止进程，也可以更改rabbitmq使用的端口
