自建DDNS配置教程(Cloudflare)
Cloudflare DDNS 腳本
1- 先至cloudflare 建立一個域名
2- 我建立了 ddns.ek12.website
3 - 進入中轉vps，建立ddns 腳本
建立ddns.sh vi /root/ddns.sh
以下內容修改加入到ddns.sh
#!/bin/sh
NEW_IP=`curl -s http://ipv4.icanhazip.com`
CURRENT_IP=`cat /tmp/current_ip.txt`
if [ "$NEW_IP" = "$CURRENT_IP" ]
then
echo "No Change in IP Adddress"
else
curl -X PUT "https://api.cloudflare.com/client/v4/zones/d7d525efbb6e7b508ed32761b07d382e/dns_records/294cdf035017050fd0529754c2ef0ad0" \
-H "X-Auth-Email: cloudfalre帳號" \ #帳號
-H "X-Auth-Key: cloudflare_API_KEY" \ #apikey
-H "Content-Type: application/json" \
--data '{"type":"A","name":"ddns.ek12.website","content":"'$NEW_IP'","ttl":120,"proxied":false}' > /dev/null #修改域名
echo $NEW_IP > /tmp/current_ip.txt
fi
3- 加入到排程， 鍵入 crontab -e
*/1 * * * * sh /root/ddns.sh
