实现阿里云DDNS解析

我有三种设备，synology openwrt raspberry

1,首先，我在openwrt上实现， 这有分为二种方法，其实也是一种方法， 1， 下载ddns-scripts_aliyun_1.0.0-1_all.ipk这个安装包，直接安装，在app-ddns里面就可以看到阿里去的服务商了， 然后输入用户名，密码就可以了。

2， 使用自定义的脚本也行，

先安装python库

pip3 install aliyunsdkcore

pip3 install aliyun-python-sdk-alidns

ddns.py

修改自己的ID KEY，主机名。

执行 python3 ddns.py &

在群晖上可以使用2种方法，1， docker, 这个我没有试。 2是使用脚本，我个我试了，比较方便， 网上下载了一个aliyun.sh， 加到群晖的自定义任务里，10分钟运行一次，就可以了，非常简单方便易行。

• www：解析后的域名为 www.1756260160.com

sh aliyun.sh <id> <secret> <主域名> <主机记录>

sh /var/services/homes/wandersky/aliddns/aliyun.sh L******************74 V0********************CMi **********.com www

脚本命令格式如上。

#!/bin/sh

exit 1
