3. 其他说明3.1 python安装3.2 问题

1. 前言

1.1 关于data-web官网

1.1.1 源码下载

https://gitee.com/liuersusu/datax-web.

1.1.2 datax-Web部署手册

1.1.2.1 Linux环境部署手册

如下：

在这里插入图片描述

1.1.2.2 本地开发环境部署手册

如下：

https://github.com/WeiYe-Jing/datax-web/blob/master/userGuid.md.

1.2 关于datax入门

2. 下载之后打包、启动、登录

2.1 我的本地环境

JDK1.8，maven3.9.0，python3.11，mysql8

2.2 修改配置

如下：

在这里插入图片描述
