启动服务时 RabbitMQ 虚拟主机错误 [英] RabbitMQ virtual host error when starting service
本文介绍了启动服务时 RabbitMQ 虚拟主机错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经运行了几个月的 RabbitMQ 服务器.今天早上我无法连接到它，我的应用程序超时并且管理客户端没有响应.重新启动了机器.应用程序仍然超时.我能够登录到管理客户端，但我看到了这条消息:
I've had a RabbitMQ server running for months. This morning I was unable to connect to it, my applications was timing out and the Management client was unresponsive. Rebooted the machine. Applications are still timing out. I'm able to login to the Management client but I see this message:
虚拟主机/在节点 rabbit@MQT01 上遇到错误，可能无法访问
Virtual host / experienced an error on node rabbit@MQT01 and may be inaccessible
我所有的队列都在那里，但看不到任何交换.
All my queues are there but can't see any exchanges.
我希望有人能帮我弄清楚发生了什么.我查看了日志，但找不到任何好的提示.
I hope someone can help me figure out what going on. I've looked at the logs but can't find any good hint.
这里是日志的一部分:

我弄清楚发生了什么.我团队中的某个人(我)正在创建与 RabbitMQ 的空前数量的连接.对于每个连接，都会为一个或多个文件创建一个文件处理程序，但不确定是哪个.操作系统(在我的例子中是 Windows)有一个文件处理程序限制，不确定限制是什么，但是当达到时，会引发错误.这损坏了虚拟主机(/)，我不得不删除它并重新创建它.幸好这不是生产，因为那样所有消息都会消失.
I figured out what was going on. Someone on my team (me) was creating an unprecedented amount of connections to RabbitMQ. For each connection a file handler is created to one or more files, not sure which. The OS (Windows in my case) has a file handler limit, not sure what the limit is, but when reached, an error is thrown. This corrupted the virtual host (/) and I had to delete it and create it again. Good thing this wasn't production, because then all the messages would've been gone.
编辑(2020 年 6 月):
可能会对此进行修复，因此它不会再次发生.可以限制虚拟主机允许的连接数.这样，Windows 就不会在许多文件句柄上出错.查看管理门户 ->管理员->限制，将最大连接数设置为您认为适合您的设置的数字.
There might be a fix for this so it can't happen again. A virtual host can be limited in how many connections they allow. This way Windows won't faulter on the many file handles. Look in the management portal -> Admin -> Limits, set max-connections to a number you think it plausible for your setup.
这篇关于启动服务时 RabbitMQ 虚拟主机错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
