Rabbitmq通过域名连接而非IP连接

ping your-rabbitmq-domain.com

nslookup your-rabbitmq-domain.com

listeners.tcp.default = 5672
loopback_users = none
default_user = guest
default_pass = guest
default_vhost = /
hostname = your-rabbitmq-domain.com

sudo systemctl restart rabbitmq-server

sudo service rabbitmq-server restart

import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(
    host='your-rabbitmq-domain.com',
    port=5672,
    credentials=pika.PlainCredentials('guest', 'guest')
))

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()
