在CentOS中可利用消息队列实现数据同步,以下是具体方法及工具:
选择消息队列系统
配置消息队列
# RabbitMQ
sudo yum install rabbitmq-server
sudo systemctl start rabbitmq-server
# Kafka
sudo yum install kafka
sudo systemctl start kafka
server.properties中配置num.partitions和replication.factor。实现数据同步逻辑
# 生产者
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()
channel.queue_declare(queue='data_sync')
channel.basic_publish(exchange='', routing_key='data_sync', body='{"key":"value"}')
connection.close()
# 消费者
def callback(ch, method, properties, body):
print(f"Received: {body}")
# 处理数据逻辑
channel.basic_consume(queue='data_sync', on_message_callback=callback, auto_ack=True)
channel.start_consuming()
inotify监控文件变化,触发消息发送。优化与监控
rabbitmqctl查看队列状态,或通过Prometheus+Grafana监控Kafka指标。跨主机同步注意事项
