python - 无法远程访问 RabbitMq 服务器

Question

我无法远程访问 RabbitMq 服务器。当我在一台机器上执行此操作并连接到 localhost:15672 时，它可以工作，但是当我从远程机器尝试时，它就不行了。

我已经创建了一个拥有所有权限的用户并检查了计算机上的 5672 端口是否正常工作(只是试图从远程计算机连接到他)。另外，我尝试连接到 15672 端口，但没有结果。

credentials = pika.PlainCredentials(username= 'username', password='password')
parameters = pika.ConnectionParameters(host='188.19.100.226',
                                   port=5672,
                                   virtual_host= '/',
                                   credentials=credentials)

connection = pika.BlockingConnection(parameters=parameters)
channel = connection.channel()

channel.queue_declare(queue='hello')

channel.basic_publish(exchange='',
                  routing_key='hello',
                  body=hello)
print ("Sent!")
connection.close()

我希望看到 Sent!，但我得到的不是:

你需要配置rabbitmq来监听本地主机以外的其他接口(interface)。 接受来自所有接口(interface)的连接，监听0.0.0.0
