RocketMQ Canal 相关笔记

解压后直接进bin启动

nohup sh mqnamesrv &
tail -f ~/logs/rocketmqlogs/namesrv.log

启动broker

nohup sh mqbroker -n 192.168.1.80:9876 &
tail -f ~/logs/rocketmqlogs/broker.log

查看

https://github.com/apache/rocketmq-externals/tree/release-rocketmq-console-1.0.0/rocketmq-console

编译成jar包

mvn clean package -Dmaven.test.skip=true

启动

java -jar rocketmq-console-ng-1.0.0.jar --server.port=8080 --rocketmq.config.namesrvAddr=192.168.171.129:9876

官方文档非常好用：
https://github.com/alibaba/canal/wiki/Canal-Kafka-RocketMQ-QuickStart

注意集成RocketMQ的配置项:
注意MQ的配置，开启发送JSON格式数据，改为true

在RocketMQ可视化界面创建 topic

出现,RocketMQ 消息队列大量重复消息需配置 mysql-binlog

instance.properties中的配置

贴一下 canal.properties

在原配置文件追加配置

# 可选项: tcp(默认), kafka, RocketMQ
canal.serverMode = RocketMQ
# ...
# kafka/rocketmq 集群配置: 192.168.1.117:9092,192.168.1.118:9092,192.168.1.119:9092
