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

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。

准备 aliddns.py

添加服务器中的定时任务

• Windows 于任务计划程序添加
• Linux 使用 cron 服务（crontab）
