我正要和Chef一起安装Sensu，但RabbitMQ似乎不起作用。即使erlang和rabbitmq安装成功，rabbitmq服务器的服务也不会启动

rabbitMQ的错误是

Error: unable to connect to node rabbit@localhost: nodedown
及

所以我用ps命令检查了rabbitmq的进程

ps aux |grep rabbitmq
确保有一个进程正在使用rabbitmq用户运行

/usr/lib64/erlang/erts-6.1/bin/epmd -daemon
我终止了该进程，并重新启动了rabbitmq服务器服务。但是，无法启动rabbitmq服务器，并且显示了相同的日志—发生了相同的事情

我曾经删除了erlang和rabbitmq并重新安装了它们，但结果是一样的

以下是详细内容

确切地说，RabbitMQ 5672使用的端口似乎已被占用。或者在你的情况下，它可能仍然是采取。若您关闭了在某个端口上打开套接字的应用程序，那个么您就并没有给它足够的时间来正确关闭此连接。系统最终会注意到这一点并释放资源，但这可能需要一些时间。所以你能做的就是等一等，或者改变一下

希望这能帮助您解决一些问题。

端口5672是否已被占用？也许您可以使用lsof进行检查？您是否使用同一用户启动rabbitmq并稍后联系它？Erlang程序必须使用相同的.Erlang.cookie文件才能相互联系在我的情况下，我在rabbitmq.config中配置了ssl_侦听器，但没有tcp_侦听器；当我使用不同的端口将tcp_侦听器添加到配置中时，服务再次开始工作。
