- Canal 给 kafka 发消息 问题
- 问题排查
- 问题原因 canal服务异常
- 解决方式
- 1、修改canal服务端kafka的配置
- 2、修改队列的最大消息体大小
- 服务启动开始发消息正常，过一段时间后不发消息， kafka 收不到Canal 的消息
- 1、zookeeper 服务日志没有问题
- 2、kafka 服务日志没有问题
- 3、canal 日志有报错
- canal 日志有两块，直接看实例日志example.log

- The request included a message larger than the max message size the server will accept.
```java canal.mq.maxRequestSize = 1048576 （默认为1m，根据需求修改） ```2、修改队列的最大消息体大小
-
/bin/kafka-topics.sh --zookeeper 162.10.10.238:9093 --alter --topic devops --config max.message.bytes=10485760
-
或是直接重新创建容器
docker run --name kafka -p 9092:9092 -e KAFKA_BROKER_ID=0 -e KAFKA_AUTO_CREATE_TOPICS_ENABLE=true -e KAFKA_ZOOKEEPER_CONNECT=ip:2182 // zookeeper 地址 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://ip:9093 // kafka 地址 -e KAFKA_MESSAGE_MAX_BYTES=10485760 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 -d wurstmeister/kafka
