首先,您需要获取阿里云的AccessKey ID和AccessKey Secret,以便于通过API进行操作。
然后,可以使用cURL命令,向阿里云的API发送HTTP请求,来实现动态DNS的功能。
以下是一个简单的阿里云DDNS shell脚本的示例:
``` #!/bin/bash
阿里云AccessKey ID
access_key_id=" "
阿里云AccessKey Secret
access_key_secret=" "
域名
domain=" "
主机记录
RR=" "
获取当前公网IP
ip=curl -s http://ipv4.icanhazip.com
构造签名参数
timestamp=date -u "+%Y-%m-%dT%H%%3A%M%%3A%SZ"
signature=echo -n "GET&%2F&AccessKeyId%3D$access_key_id%26Action%3DDescribeDomainRecords%26DomainName%3D$domain%26Format%3DXML%26SignatureMethod%3DHMAC-SHA1%26SignatureNonce%3D$RANDOM%26SignatureVersion%3D1.0%26Timestamp%3D$timestamp%26Type%3D" | openssl dgst -binary -sha1 -hmac "$access_key_secret&" | base64
获取解析记录的ID
record_id=curl -s "http://alidns.aliyuncs.com/?Action=DescribeDomainRecords&DomainName=$domain&Format=XML&Signature=$signature&SignatureMethod=HMAC-SHA1&SignatureNonce=$RANDOM&SignatureVersion=1.0&Timestamp=$timestamp&Type=&AccessKeyId=$access_key_id" | grep "<RecordId>" | awk -F "<RecordId>" '{print $2}' | awk -F "<" '{print $1}'

如果IP有变化,则更新DNS记录
if [ $ip != $record_id ] then timestamp=date -u "+%Y-%m-%dT%H%%3A%M%%3A%SZ"
signature=`echo -n "GET&%2F&AccessKeyId%3D$access_key_id%26Action%3DUpdateDomainRecord%26DomainName%3D$domain%文章来源地址https://www.toymoban.com/news/detail-752428.html
