CloudCone美国VPS，DD安装alpine操作系统
提示：此脚本为CloudCone专用，其他服务商的VPS请勿使用！
大概5分钟左右完毕，然后重启后大概1分钟左右就可以了。
本人未测试此脚本！操作过程会清空服务器数据，谨慎使用。
wget --no-check-certificate https://donghaiair.com.cn/cloudcone2alpine.sh && chmod +x cloudcone2alpine.sh && ./cloudcone2alpine.sh
脚本防删备份：
#!/bin/sh
## cloudcone专用版，ovz6、ovz7、kvm请使用对应版本
