[rabbitmq-discuss] can not connect to rabbitmq because pika.exceptions.ProbableAuthenticationError

[鞠大升]

hi, all

I am newer to rabbitmq.

I install a rabbitmq, just download, setup and startup the server. then I 
use a simple python client to connect, but the client report a error.

=================================================
Here is my version config:
python: 2.7
rabbitmq:  rabbitmq-server-generic-unix-3.1.5.tar.gz
erlang: otp_src_R16B01
pika: master

=================================================
Here is my python client:
#!/usr/bin/env python
import pika

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


channel.queue_declare(queue='hello')

channel.basic_publish(exchange='',
            routing_key='hello',
            body='Hello World!')
print " [x] Sent 'Hello World!'"
connection.close()

=================================================
Here is the error info:
