一、通過python模擬收發訊息

1、在各個節點上安裝epel源

# yum install  epel*  -y

2、安裝python庫

# yum --enablerepo=epel -y install python2-pika

3、在rabbitmq-server節點上
1）、建立使用者

# rabbitmqctl add_user wuyeliang password 

2）、建立虛擬主機

# rabbitmqctl add_vhost /my_vhost

3）、賦予許可權

# rabbitmqctl set_permissions -p /my_vhost wuyeliang ".*"
 
 ".*" ".*" 

4、在rabbitmq節點上模擬發訊息，程式碼如下

# vi send_msg.py
#!/usr/bin/env python
import pika
credentials = pika.PlainCredentials('wuyeliang', 'password') #注意使用者名稱及密碼
connection = pika.BlockingConnection(pika.ConnectionParameters(
                                     'localhost',
                                     5672
 
,
                                     '/my_vhost',
                                     credentials))
channel = connection.channel()
channel.queue_declare(queue='Hello_World')
channel.basic_publish(exchange='',
                      routing_key='Hello_World',
                      body='Hello RabbitMQ World!'
 
)
print(" [x] Sent 'Hello_World'")
connection.close()

4、在client節點上模擬收訊息，程式碼如下

# vi receive_msg.py
 #!/usr/bin/env python
import signal
import pika
signal.signal(signal.SIGPIPE, signal.SIG_DFL)
signal.signal(signal.SIGINT, signal.SIG_DFL)
credentials = pika.PlainCredentials('wuyeliang', 'password')
connection = pika.BlockingConnection(pika.ConnectionParameters(
                                     'dlp.srv.world',
                                     5672,
                                     '/my_vhost',
                                     credentials))
channel = connection.channel()
channel.queue_declare(queue='Hello_World')
def callback(ch, method, properties, body):
    print(" [x] Received %r" % body)
channel.basic_consume(callback,
                      queue='Hello_World',
                      no_ack=True)
print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()
