Maxwell 安装与使用

1、下载(建议使用github上的)

http://maxwells-daemon.io/quickstart/    # version > 1.30 jdk需要使用11版本
https://github.com/zendesk/maxwell/releases  # version <1.30 jdk使用8版本

2、解压

tar -xf  xxx.tar.gz

3、运行示例 http://maxwells-daemon.io/quickstart/

bin/maxwell --user='maxwell' --password='XXXXXX' --host='127.0.0.1' \
   --producer=kafka --kafka.bootstrap.servers=localhost:9092 --kafka_topic=maxwell

4、通过config.properties运行  (增量监听)

#mysql
user=root
password=yang156122
host=hadoop101
#kafka
producer=kafka
kafka.bootstrap.servers=hadoop101:9092
kafka_topic=kafkaeagle1

../bin/maxwell --config config.properties

解决方法：maxwell1.33版本要使用jdk11，因此要么就升级jdk,要么就使用maxwell低版本(小于1.30版本)
