**Is your feature request related to a problem? Please describe.** I'm confused when I follow the section to build the db, because there is no description about MySQL db. When I use the MySQL db, I need to specify the mysql scope as compile in pom.xml to avoid the exception of ClassNotFound for `com.mysql.jdbc.Driver`(5.x) or `com.mysql.cj.jdbc.Driver`(8.x). **Describe the solution you'd like** We need to add specific MySQL description in this section. **Additional context** There is the description in [搭建后端] section: `创建表和初始化数据： 修改dao模块resource目录下application.properties文件中的数据库配置信息，然后执行org.apache.dolphinscheduler.dao.upgrade.shell.CreateDolphinScheduler的类，运行完，刷新数据库，表和数据都有了。` There is the [link](https://dolphinscheduler.apache.org/zh-cn/docs/1.2.0/user_doc/development-environment-setup.html). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
