1、安装datax
安装参考[linux安装dataX-CSDN博客](https://blog.csdn.net/hzp666/article/details/127350768)
2、配置datax同步mysql
配置mysql隔离级别,进入mysql终端
SET GLOBAL transaction_isolation='READ-COMMITTED';
配置数据源
jdbc:mysql://16gmaster:33060/studio?useUnicode=true&characterEncoding=utf8&useLocalSessionState=true


配置执行器

配置任务模版

配置单任务
按步骤选择数据抽取库,数据合并库,映射字段,构建datax的可执行json文件,选择任务模版,点击下一步任务就创建完成了,可以在任务详情里查看




最后可以运行的json文件
