使用Python 、 go 语言测试rabbitmq的工作机制

1：在haproxy 和 rabbitmq上安装Python、python2-pip，默认是Python2

yum install -y python python2-pip

 

2：在haproxy 和 rabbitmq上使用pip安装pika库

pip install pika==0.9.8

 

3：在haproxy上写一个Python发送消息代码

vi send.py

-------

#!/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 Uplooking!')

print "Sent 'Hello Uplooking!'"

connection.close()

-------

 

4：在rabbitmq上写一个Python接受消息代码

vi receive.py

-------

#!/usr/bin/env python

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(

host='localhost'))

channel = connection.channel()

channel.queue_declare(queue='hello')

print ' waiting for messages! press CTRL+C to halt'

def callback(ch, method, properties, body):

print "Received %r" % (body,)

channel.basic_consume(callback,

queue='hello',

no_ack=True)

channel.start_consuming()

-------

 

5：先运行receive.py，在运行send.py

python receive.py

python send.py
