Ubuntu/debian 网络安装或者重装centos6.9系统,适用大部分云

2018年5月13日 4369点热度 0人点赞 0条评论

谷歌云,微软云等都有centos debian ubuntu ,可Amazon Lightsail没有centos

google了一下有大佬写了一键脚本,测试很好用

条件：GRUB引导、非OVZ虚拟化
架构：X64
X86需要跟换源

特别注意:OpenVZ构架不适用

wget -qO- https://git.io/vp9te && bash centos.sh

或者

curl -Lso- https://git.io/vp9te && bash centos.sh

基本默认密码是passwd,成功后记得修改root密码

测试
测试了AWS-LightSail下重装，Ubuntu 16.04 能正常重装到 CentOS 6.9 机房日本东京
速度12-30分钟。其他的后面再测试

需要需要其他的,CentOS/Debian/Ubuntu网络重装系统一键脚本,可以去试试萌咖 && 狗仔小分队

Ubuntu/debian 网络安装或者重装centos6.9系统,适用大部分云

谷歌云,微软云等都有centos debian ubuntu ,可Amazon Lightsail没有centos

google了一下有大佬写了一键脚本,测试很好用
