我这么理解是对的吗?

你提供的内容有:

  • 脚本内容:获取本机的IP地址,并将其上传至Godaddy的相关域名。

需要自己添加的命令:

  • 定时任务:每隔多少分钟,执行这个脚本。

具体玩儿法
1、创建一个xxx.sh 文件,将你的脚本文件复制粘贴,并将 Key、Secret、Domain、Name 填写对应的内容,其它文件不修改,然后保存退出。
2、使用chmod +x * 命令将 xxx.sh文件 改为可执行文件。
3、./xxx.sh 运行一下,然后登陆Godaddy查看是否更新成功
4、创建定时任务,将xxx.sh脚本定时运行。

完。

应该是获取本机的 IP 地址,与 DNS 服务器上 A 记录指向的地址做对比,不一致的话更新 godaddy 的相关记录。

其实很简单,适用于路由器不支持 DDNS 的网络使用。

我已经在使用你的这个脚本了,刚好可以解决动态IP的问题。
然后执行命令后有个提示说,第13行 dig:未找到命令

虽然没啥影响,但是强迫症看到提示,就想解决这个问题,请问这是什么原因导致的?

来自新手的疑问。

哦,你需要安装 dig 这个工具,ubuntu 的话应该是 $ sudo apt-get install dnsutils 就可以了。

路由器运行sh
错误提示
[Router /home/id]# ./godaddy_ddns.sh
New public IP is 100.11.xx.xx
curl: (51) Cert verify failed: BADCERT_NOT_TRUSTED
如果我使用跳过
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
则提示

syntax error: unexpected word (expecting ")")

头疼,暂时还没看到godaddy更新ip.
