3.安装不可描述脚本

```auto
curl -s https://raw.githubusercontent.com/233boy/sing-box/refs/heads/main/install.sh|bash

```

4.使用sed替换脚本生成的IP和端口

6.添加crontab 完事手工

```auto
echo '0 */12 * * * /bin/bash /root/.ssh/cf_ddns.sh' | crontab -

```

```auto
cat > /root/.ssh/cf_ddns.sh << 'EOF'
#!/bin/bash
auth_token=""
zone_id=""
record_name=""

ip=$(curl -s4 ip.sb) || exit 1
[-z "$ip"] && exit 1

auth=("-H" "Authorization: Bearer $auth_token" "-H" "Content-Type: application/json")

record=$(curl -s "https://api.cloudflare.com/client/v4/zones/$zone_id/dns_records?name=$record_name&type=A" "${auth[@]}")
[-z "$record"] && exit 1

if [["$record" == *'"count":0'*]]; then
  curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$zone_id/dns_records" \
    "${auth[@]}" --data "{\"type\":\"A\",\"name\":\"$record_name\",\"content\":\"$ip\",\"ttl\":120,\"proxied\":false}"
  exit $?
fi

id=$(echo "$record" | sed -n 's/.*"id":"\([^"]*\)".*/\1/p')
old_ip=$(echo "$record" | sed -n 's/.*"content":"\([^"]*\)".*/\1/p')

["$ip" = "$old_ip"] && exit 0

curl -s -X PUT "https://api.cloudflare.com/client/v4/zones/$zone_id/dns_records/$id" \
  "${auth[@]}" --data "{\"type\":\"A\",\"name\":\"$record_name\",\"content\":\"$ip\",\"ttl\":120,\"proxied\":false}"
EOF

chmod +x /root/.ssh/cf_ddns.sh
(crontab -l 2>/dev/null; echo "0 */12 * * * /bin/bash /root/.ssh/cf_ddns.sh") | crontab -

```

其实最后面的ddns脚本还可以再精简一下，很简单的东西，判断解析的IP是否是机器最新IP然后更新
