RabbitMQ 随机崩溃

  • 772

我最近按照基于 RPM 的 Linux 发行版的说明在 AWS 上部署了 RabbitMQ 服务器。

RabbitMQ 3.8.14
Erlang 23.3.1

这是一个只有一个虚拟主机（“/”）的单节点部署，我主要使用默认配置。我还修改了打开文件的限制，最初为 65536，目前为 150000。虽然使用的文件描述符保持在相对较低的水平。

我有两个连接到 RabitMQ 的应用程序。每个应用程序都使用自己的用户名和密码进行身份验证。两个用户都对虚拟主机和他们使用的主题拥有完全的权限。

我已经设置了 7 个交换和队列。都很耐用。

服务器启动没有任何问题，应用程序运行正常，能够与服务器通信，没有问题并从主题中消费，但它们随机崩溃。

在 rabbitmq 日志文件中，我可以看到以下内容

崩溃后，除非我重新启动 RabbitMQ 服务器，否则应用程序无法恢复并与 RabbitMQ 通信。

此外，当我检查时，rabbitmq-server.service我可以看到它处于活动状态。

当我检查时也会发生同样的事情rabbitmq-diagnostics is_running

Asking node rabbit@rabbitmq-test1 for its status ...
RabbitMQ on node rabbit@rabbitmq-test1 is fully booted and running

到目前为止，我还没有找到关于何时发生这种情况的模式。关于为什么会发生这种情况的任何想法？

2 个回答

  1. Best Answer

    事实证明，这个问题与 rabbitMQ 配置无关。这是由于应用程序和 MongoDB（我们也在使用）之间的通信缓慢导致应用程序和 RabbitMQ 之间的连接超时。

  2. 您正在处理错误的 forloop 并且内存不足，因为您正在打开许多通道或连接，试图处理每个交换和每个交换中持有的队列之间的通信。最有可能的。

    当您再次启动脚本时，查看您有多少个连接以及您有多少个频道。如果您的应用程序正在接收不遵循任何模式的消息，并且您不正确地循环通过每个交换和每个队列以引导每条消息，那么您将耗尽您的内存而没有模式来复制问题，因为进入您的发布者的消息遵循没有因此，理性模式很难缩小问题所在。从开始到结束，您的连接时间戳似乎在很短的时间内，这表明您正在接收大量消息，并且您的 for 循环正在为每个交换和队列创建不必要的连接，因为您没有处理 forloop 和连接后者正确。
