使用老毛子在腾讯云DNSpod上实现DDNS

需求：
1. 一台刷了老毛子的路由器
2. 腾讯云上购买的域名

最近申请了电信的动态公网IP，就想着我之前买的域名可以用起来了，于是乎查阅资料在路由器上实现了DDNS

首先在GitHub上搜索DDNS，找到了一个可用的shell脚本rehiy/dnspod-shell为了方便拷贝到路由器，按照作者的方法把配置融合进了单文件内，文件修改好备用
复制进老毛子，浏览器输入192.168.123.1进入老毛子管理界面，依次点击高级设置中的系统管理-服务-启用ssh服务选择“是”
打开FinalShell或者其他ssh软件登录路由器，选择新建ssh连接，地址就是192.168.123.1，用户名密码就是你设置的密码，进入之后把改好的.sh文件复制到路由器/etc/storage/目录下
在计划任务那里输入*/10 * * * * /etc/storage/ardnspod.sh代表10分钟运行一次，最后点击“应用本页面设置”即可。
最后为了能够方便管理，我把代码的输出改到了系统日志输出，这样就可以在路由器管理界面看到运行效果啦

改过的代码我放在最后，只需要改最后两行的arToken和arDdnsCheck即可，arToken可以登录DNSpod点击右上角我的账号-api密钥

然后选择创建DNSpod Token即可获取，arToken格式为ID,Token
如果感觉不错的话请点个小哈。文章来源地址https://www.toymoban.com/news/detail-454938.html
