RabbitMQ 在 WSO2 微积分器中连接失败，连接服务器的方法是什么？

Question

我创建了一个入站端点来从 RabbitMQ 代理检索消息并以另一个顺序记录它们，当我在本地安装的 RabbitMQ 服务器中尝试时它工作正常，但我无法连接到远程 Z7EAA99323E57B3EFC179 主机

Answer 1

你的配置看起来不错。 这似乎是一个网络问题。 您是否有任何防火墙限制 WSO2 访问 Rabbit 服务器？ 执行以下调试。

ping 服务器并查看主机名是否解析

ping -a rabbitmq-ts.sl

如果Hostname可以解析，telnet看看能不能连接到AMQP端口

telnet rabbitmq-ts.sl 5672
