能看懂的用，不做解释了，麻烦。
支持大部分Centos机器，理当支持ORALCE，做了EFI兼容支持
本想加入Centos6支持，但又要花费精力，也没人用6了，就没支持
Centos8只需要提示输入repo的输入centos8的源就行，不过你的内存得大于2G，
小于1G的就用默认的吧，链接VNC以后再进去切换安装源刀最新版的Centos
测试机器本机HYPER-V开的机器。阿里云轻量，腾讯云轻量，AWS轻量
还在DD别人的Centos吗，分区不是自己想要的分区吗？使用本脚本即可可视化安装centos！
自己存脚本吧，
临时URL https://uploader.shimo.im/f/EWp1RmhLMYQJBp3a.sh
使用方法：bash
用完以后别再BB说我植入脚本了，任何后果自负
