Rabbitmq hello world 連接僅適用於本地主機（python）

Question

我有這個來自rabbitmq教程的簡單代碼（ http://www.rabbitmq.com/tutorials/tutorial-one-python.html ）

import pika
import logging

logging.basicConfig()

connection = pika.BlockingConnection(pika.ConnectionParameters(
       host='localhost'))

channel = connection.channel()

channel.queue_declare(queue='hello')

print ' [*] Waiting for messages. To exit press CTRL+C'

def callback(ch, method, properties, body):
    print " [x] Received %r" % (body,)

channel.basic_consume(callback,
                      queue='hello',
                      no_ack=True)

channel.start_consuming()

它可以工作，但是如果我從我自己的計算機或同一網絡中的計算機使用我計算機的 ip 更改 localhost：

connection = pika.BlockingConnection(pika.ConnectionParameters(
       host='192.168.60.126'))

我收到此錯誤：

我不知道為什么，我應該更改連接中的某些內容嗎？

Answer 1

作為對@Gas 響應的跟進。

默認情況下，pika 將使用默認的 RabbitMQ 憑據guest/guest 。 如果要使用自己的憑據，則需要提供自己的PlainCredentials對象。

credentials = pika.PlainCredentials(username='my_user', password='password')
connection = \
    pika.BlockingConnection(pika.ConnectionParameters(host='192.168.60.126',
                                                      credentials=credentials))

在服務器上，您需要添加具有適當權限的用戶。 您可以使用 Web 界面或命令行執行此操作。 @Gas 提供的鏈接中提供了更多詳細信息。

rabbitmqctl add_user my_user password
rabbitmqctl set_permissions -p / my_user ".*" ".*" ".*"

這兩個命令將為用戶my_user提供它在虛擬主機/上my_user所有權限。

Answer 2

這是一個用戶授權問題。

您正在使用默認用戶“guest”。

Answer 3

對於 macOS，您需要編輯/usr/local/etc/rabbitmq/rabbitmq-env.conf ，其中NODE_IP_ADDRESS=0.0.0.0而不是localhost
