(一)安装一个消息中间件,如:rabbitMQ
(二)生产者
sendmq.py

import pika
import sys
import time
# 远程rabbitmq服务的配置信息
username = 'admin' # 指定远程rabbitmq的用户名密码
pwd = 'admin'
ip_addr = '10.1.7.7'
port_num = 5672
# 消息队列服务的连接和队列的创建
credentials = pika.PlainCredentials(username, pwd)
connection = pika.BlockingConnection(pika.ConnectionParameters(ip_addr, port_num, '/' , credentials))
channel = connection.channel()
# 创建一个名为balance的队列,对queue进行durable持久化设为True(持久化第一步)
channel.queue_declare(queue = 'balance' , durable = True )
message_str = 'Hello World!'
for i in range ( 100000000 ):
# n RabbitMQ a message can never be sent directly to the queue, it always needs to go through an exchange.
channel.basic_publish(
exchange = '',
routing_key = 'balance' , # 写明将消息发送给队列balance
body = message_str, # 要发送的消息
properties = pika.BasicProperties(delivery_mode = 2 , ) # 设置消息持久化(持久化第二步),将要发送的消息的属性标记为2,表示该消息要持久化
) # 向消息队列发送一条消息
print ( " [%s] Sent 'Hello World!'" % i)
# time.sleep(0.2)
connection.close() # 关闭消息队列服务的连接

运行sendmq.py文件,可以从以下方法查看队列中的消息数量。
一是,rabbitmq的管理界面,如下图所示:
二是,从服务器端命令查看
rabbitmqctl list_queues
(三)消费者
receivemq.py

# time.sleep(0.2)
# 开始依次消费balance队列中的消息
channel.basic_consume(queue = 'balance' , on_message_callback = callback, auto_ack = True )
print ( ' [*] Waiting for messages. To exit press CTRL+C' )
channel.start_consuming() # 启动消费

运行receivemq.py文件,可以从以下方法查看队列中的消息数量。
或者
rabbitmqctl list_queues
延伸:
systemctl status rabbitmq-server.service # 状态
systemctl restart rabbitmq-server.service # 重启
