linux – RabbitMQ,麻烦得到hello world示例除了localhost之外的

我正在学习RabbitMQ,并在 http://www.rabbitmq.com/tutorials/tutorial-one-python.html运行hello world示例,localhost没有问题.现在我想测试从我的PC到另一台服务器的消息,receive.py似乎永远不会得到任何消息.也许我没有正确指定主机名？

Receive.py：

#!/usr/bin/env python
import pika
import json

connection = pika.BlockingConnection(pika.ConnectionParameters(
        host='66.175.x.x'))
channel = connection.channel()

channel.queue_declare(queue='hello')

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

def callback(ch,method,properties,body):
    data = json.loads(body)
    print "Log filename is " + data["filename"]
    print data["content"]

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

channel.start_consuming()

send.py：

#!/usr/bin/env python
import pika
import json
import sys

filename = sys.argv[1]
logdata = open(filename,'r').read()

connection = pika.BlockingConnection(pika.ConnectionParameters(
        host='66.175.x.x'))
channel = connection.channel()

channel.queue_declare(queue='logupload')
n = filename.rfind('')
if n != -1:
    filename = filename[n + 1:]
data = {"filename":filename,"logdata":logdata}

channel.basic_publish(exchange='',routing_key='logupload',body=json.dumps(data))
connection.close()
print "sent %s %d bytes" % (filename,len(logdata))
