create db2 connection error

[ifeng2025]

Version : 1.3.1
i try to create a db2 connection ,
whether to fill in the JDBC link parameters or not, it always fails
and i don't found the log , can't exclude the error

1. Whether the db2 driver is placed in the lib directory, and restart the dolphinscheduler api/master/worker service
2. Test connection The log is generated in the api service, see if you can find it

---

1.db2 driver 是否放到lib 目录下，并重启dolphinscheduler api/master/worker 服务
2.测试连接 日志是在api 服务生成的，看能不能找到

@ifeng2025 你好，你按照官方文档已经搭建好了吗？ 如果有自己的安装文档的话可否提供一下，官方文档中的坑太多了，现在按照文档确认是无法安装成功的

谢谢回复，我遇到了一堆问题，官方文档真的是太坑了，完全不能用，百度解决的
安装完成后打开一直是 Loading ... 并且官方提供的源码包中dockerfile也不能正确构建 不知道为什么会有4.3K的star

按照文档执行 最后根本就没有12345这个端口 这个文档同样的坑 根本无法访问

[xingchun-chen]

Check whether there is db2jcc4.jar in the lib directory of the installation directory

could you submit an issue to describe the problem you meet？

when you click connection test ， you will see the runtime log under logs, the log file name start with 'dolphinscheduler-api'
