无法在CentOS 6.5上启动RabbitMQ服务器
无法在CentOS 6.5上启动RabbitMQ服务器
提问于 2014-08-06 21:09:56
我正要和厨师一起安装Sensu，但是RabbitMQ似乎不能工作。即使erlang和RabbitMQ安装成功，rabbitmq-server的服务也无法启动。
rabbitMQ的错误是
Error: unable to connect to node rabbit@localhost: nodedown和
rabbitmq service has already started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-server服务。然而，启动rabbitmq-server失败，相同的日志显示相同的事情，同样的事情发生。
我曾经删除了erlang和rabbitmq，并重新安装了它们，但结果是一样的。
以下是详细信息。

看起来RabbitMQ (准确地说是5672)正在使用的端口已经被占用了。或者在你的情况下，它可能还会被拿走。如果您终止在某些端口上打开套接字的应用程序，则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。因此，您可以稍等片刻，或者更改RabbitMQ configuration。
希望这能帮助你解决一些问题。
