利用宝塔面板实现阿里云DDNS更新
由于我的N1在Armbian上安装了宝塔面板，并架设了NextCloud(性能低下)所以还是装了Cloudreve，利用IPv6实现外网的便捷访问。Docker使用仅仅是为了DDNS还是很浪费资源的。所以就使用宝塔的计划任务来实现吧！
其中的更新时间建议每天执行，当然也可以更频繁些，例如N小时一次。

参数说明：
AccessKey ID：
aliddnsipv6_ak="**********"
Access Key Secret
aliddnsipv6_sk="************************"
子域名：
aliddnsipv6_name1='www'
域名：
aliddnsipv6_domain='xxx.com'
TTL:
aliddnsipv6_ttl="600"
show:etho 是指定网卡获取IPv6，可通过ifconfig命令来获取网卡名
ipv6s=ip addr show eth0 | grep "inet6.*global" | awk '{print $2}' | awk -F"/" '{print $1}' || die "$ipv6"
配置好了之后保存，可以尝试执行一次看是否已经生效，如果正常就OK啦！是不是很简单？
