DolphinScheduler2.0版本升级3.0版本方案

1.升级背景

因项目需要使用数据质量模块功能，可以为数仓提供良好的数据质量监控功能。故要对已有2.0版本升级到3.0版本以上，此次选择测试了3.0.1 和 3.1.1 两个版本，对进行同数据等任务调度暂停等操作测试，最后选择3.0.1 版本

原因：

1. 3.1.1 在测试sql任务时 ，同时启动上百sql 任务时，会出现sql 任务报错，导致大量任务无法正常运行，询问社区大佬，这是DS本身bug导致，虽然此现象在3.0.1也有出现，不过出现几率较小。

2. DS3.0.1以上版本zookeeper的依赖版本进行了更新，查看驱动版本是3.8版本。我们生产不打算升级zk,故选择使用3.0.1版本。

此版本测试还是比较稳定的，功能比较完善，满足我们使用需求。

此次升级已经验证可行性，已在生产环境验证上线，对已有的问题，并给出了合理的解决方便，故写此篇文章，供各位同学参考。

2.升级的方案

选定方案：

采用数据库表同步的方式进行任务迁移，前期3.0 版本 和 2.0 版本同时运行，任务再验证没问题后，再逐步停止2.0版本。

原因：直接使用官网提供的升级脚本，无法正常运行，有较多问题，目前我们改造后，升级的数据库信息没问题，运行时数据信息有损坏，导致较多问题，所以为安全稳定，不直接使用官网提方案。

3.升级准备

1.首先对已有数据库进行备份，此项非常重要,

备份原始DS库：
 mysqldump -h ip -P 3306 -u 用户 -p 密码 数据库名  > /opt/new_dolphinscheduler.sql

恢复到新库：
　　mysql -u 用户 –p 密码 数据库名 < 备份文件.sql

2.对已有备份表进行表结构变更

####此脚本是官网脚本改的，添加了字段

4.安装3.0.1 DS

具体安装参考官网，创建新库，这里不做介绍。

introduction (apache.org)

5.把DS2.0数据导入数据库

需要重点注意：

次脚本导入时：

1.定时调度 状态全设置为下线状态 定时表 中 t_ds_schedules release_state 全设置为0了，为了防止和原调度冲突，测试完成后需要手动上线即可。

2.worker 分组组信息需要重新设置，和原先保持一致即可。

3.告警实例管理需要重新添加，然后在告警组管理中重新绑定。

6.遇到问题和解决方案

1.任务无法打开
如直接使用官网任务脚本会报次错误，这保存可以直接看日志，是由于字段缺少导致的，上面ddl语句中已经添加相关字段语句。

2.会出现少量任务无法保存问题，主要原因主键冲突造成的
最简单解决方案：
重新复制一个任务，在新任务中进行更改保存

3.用户授权的任务需要进行重新授权。
