我对 rabbitmq 很陌生，我在一个 EC2 实例上安装了 rabbitmq-server，并想在另一个 EC2 实例上创建一个使用者。
但我收到了这个错误：
socket.gaierror: [Errno -2] Name or service not known
那是节点状态：
ubuntu@ip-10-147-xxx-xxx:~$ sudo rabbitmq-server restart
ERROR: node with name "rabbit" already running on "ip-10-147-xxx-xxx"
DIAGNOSTICS
===========
nodes in question: ['rabbit@ip-10-147-xxx-xxx']
hosts, their running nodes and ports:
- ip-10-147-xxx-xxx: [{rabbit,46074},{rabbitmqprelaunch4603,51638}]
current node details:
- node name: 'rabbitmqprelaunch4603@ip-10-147-xxx-xxx'
- home dir: /var/lib/rabbitmq
- cookie hash: Gsnt2qHd7wWDEOAOFby=
这就是消费者代码：
import pika
cred = pika.PlainCredentials('guest', 'guest')
conn_params = pika.ConnectionParameters('10-147-xxx-xxx', credentials=cred)
conn_broker = pika.BlockingConnection(conn_params)
conn_broker = pika.BlockingConnection(conn_params)
channel = conn_broker.channel()
channel.exchange_declare(exchange='hello-exchange', type='direct', passive=False, durable=True, auto_delete=False)
channel.queue_declare(queue='hello-queue')
channel.queue_bind(queue='hello-queue', exchange='hello-exchange', routing_key='hola')
def msg_consumer(channel, method, header, body):
channel.basic_ack(delivery_tag=method.delivery_tag)
if body == 'quit':
channel.basic_cancel(consumer_tag='hello-consumer')
channel.stop_consuming()
else:
print body
return
channel.basic_consume(msg_consumer, queue='hello-queue', consumer_tag='hello-consumer')
channel.start_consuming()
