python实现阿里云域名ipv4和ipv6 ddns

1.前言

首先得有一个阿里云的域名：https://www.aliyun.com/minisite/goods?userCode=jdjc69nf

然后你的IP必须是公网IP，不然解析了也没用。

本文章讲怎样通过阿里云的SDK来添加修改域名解析，检查本机IP与解析的IP是否一致，不一致自动修改解析，达到动态解析的目的，主要用于家庭宽带这些动态IP的地方。

2.安装阿里云SDK和其他第三方库

pip install aliyun-python-sdk-core-v3
pip install aliyun-python-sdk-domain
pip install aliyun-python-sdk-alidns
pip install requests

3.获取accessKeyId和accessSecret

可以在阿里云控制台个人中心直接获取，但是一般建议使用RAM角色来进行权限控制，这样这个accessKey和accessSecret就只能操作域名，不能操作其他的资源，相对会比较安全。关于RAM快速入门：https://help.aliyun.com/document_detail/28637.html?source=5176.11533457&userCode=jdjc69nf

4.源码下载-官方

4.1 下载地址

gitee：https://gitee.com/zeruns/aliddns_Python
github：https://github.com/zeruns/-Python-aliddns_ipv4-ipv6

将aliddns.py文件下载下来。

然后用notepad++或其他编辑器打开，按照注释提示修改并保存。

然后运行一下看看有没有问题：

打开cmd输入python 脚本目录

6.设置定时任务

6.1 Linux操作

使用crontab -e写入定时任务即可。例如：

6.2 windows操作

右键点击电脑左下角，再点击计算机管理

点击任务计划程序，再点击创建任务，输入要设置的任务名称。

新建触发器，执行间隔可以自己设置，持续时间改成无限期。

新建操作，这一步很重要，配置错误就会导致脚本文件执行不成功！！！

最后确认就行。
