Question

我在机器A上运行Rabbitmq服务器，可以将任务放入消息队列。机器B应该连接到机器A上的AMQP服务器并执行任务。我的rabbitmq-env.conf设置为：

NODE_IP_ADDRESS=
NODE_PORT=5672

我可以在本地连接到机器A上的服务器。运行时nmap -p 5672 localhost。它显示：

Nmap scan report for localhost (127.0.0.1)
Host is up (0.000094s latency).
PORT     STATE SERVICE
5672/tcp open  amqp

但是在机器B上，当运行Celery工作者时，它说：

consumer: Cannot connect to amqp://myuser:**@{server_IP}:5672/myvhost: timed out.

nmap -p 5672 {server_IP}显示：

Host is up (0.0013s latency).
PORT     STATE    SERVICE
5672/tcp filtered amqp

我可以肯定我在Celery中的Broker url设置是正确的，而且我没有使用rabbitmq的访客帐户。

我的服务器状态显示：

机器A和机器B都是同一项目下的Google Compute Engine VM。任何输入将不胜感激。非常感谢。

事实证明这是一个安全问题。 Rabbitmq默认侦听所有Internet接口，并且只要所使用的帐户不是guest虚拟机，就允许远程连接。对于GCE实例之间的连接，应使用内部IP地址或仅使用实例名称。默认情况下允许内部连接。但谷歌禁止外部的。所以只需将'server_IP'更改为内部IP或实例名称，所有内容都像魔术一样。

客户端无法连接到远程Rabbitmq服务器
