1、kafka-producer

kafka-producer：https://maxwells-daemon.io/config/#kafka-producer

2、运行一个Docker容器，该容器内运行的是Zendesk的Maxwell工具，一个用于实时捕获MySQL数据库变更并将其发布到Kafka或其他消息系统的应用

docker run -it --rm zendesk/maxwell bin/maxwell \--user=maxwell \--password=maxwell \--host=192.168.74.148 \--port=3306 \--producer=kafka \--kafka.bootstrap.servers=192.168.74.148:9092 \--kafka_topic=maxwell

[root@localhost ~]# docker ps

3、进入kafka容器内部

[root@localhost ~]# docker exec -it kafka /bin/bash 
bash-5.1# kafka-console-consumer.sh --bootstrap-server 192.168.74.148:9092 --topic maxwell

4、tingshu_album 数据库中 新增数据

[root@localhost ~]# docker exec -it kafka /bin/bash
bash-5.1# kafka-console-consumer.sh --bootstrap-server 192.168.74.148:9092 --topic maxwell
{"database":"tingshu_album","table":"base_category1","type":"insert","ts":1726743970,"xid":10619,"commit":true,"data":{"id":17,"name":"kafka","order_num":0,"create_time":"2024-09-19 11:06:10","update_time":"2024-09-19 11:06:10","is_deleted":0}}

{"database": "tingshu_album","table": "base_category1","type": "insert","ts": 1726743970,"xid": 10619,"commit": true,"data": {"id": 17,"name": "kafka","order_num": 0,"create_time": "2024-09-19 11:06:10","update_time": "2024-09-19 11:06:10","is_deleted": 0}
}

5、tingshu_album 数据库中 更新数据

[root@localhost ~]# docker exec -it kafka /bin/bash
bash-5.1# kafka-console-consumer.sh --bootstrap-server 192.168.74.148:9092 --topic maxwell
{"database":"tingshu_album","table":"base_category1","type":"insert","ts":1726743970,"xid":10619,"commit":true,"data":{"id":17,"name":"kafka","order_num":0,"create_time":"2024-09-19 11:06:10","update_time":"2024-09-19 11:06:10","is_deleted":0}}

{"database": "tingshu_album","table": "base_category1","type": "update","ts": 1726744191,"xid": 11128,"commit": true,"data": {"id": 17,"name": "xxx","order_num": 0,"create_time": "2024-09-19 11:06:10","update_time": "2024-09-19 11:09:51","is_deleted": 0},"old": {"name": "kafka","update_time": "2024-09-19 11:06:10"}
}

6、tingshu_album 数据库中 删除数据

[root@localhost ~]# docker exec -it kafka /bin/bash
bash-5.1# kafka-console-consumer.sh --bootstrap-server 192.168.74.148:9092 --topic maxwell
{"database":"tingshu_album","table":"base_category1","type":"insert","ts":1726743970,"xid":10619,"commit":true,"data":{"id":17,"name":"kafka","order_num":0,"create_time":"2024-09-19 11:06:10","update_time":"2024-09-19 11:06:10","is_deleted":0}}

{"database":"tingshu_album","table":"base_category1","type":"delete","ts":1726744396,"xid":11623,"commit":true,"data":{"id":17,"name":"xxx","order_num":0,"create_time":"2024-09-19 11:06:10","update_time":"2024-09-19 11:09:51","is_deleted":0}}

{"database": "tingshu_album","table": "base_category1","type": "delete","ts": 1726744396,"xid": 11623,"commit": true,"data": {"id": 17,"name": "xxx","order_num": 0,"create_time": "2024-09-19 11:06:10","update_time": "2024-09-19 11:09:51","is_deleted": 0}
}
