Debian Network Reinstall Script
甲骨文云服务器:重装 Debian
下载脚本:
curl -fLO https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh && chmod a+rx debi.sh
运行脚本:
sudo ./debi.sh --cdn --network-console --ethx --bbr --user root --password <这里设置 root 密码>
- 以上命令选项开启了 BBR;设置了网卡名称形式是
eth0
而不是ens3
这种。 - 如果是一般的 x86 架构 64 位机器(不是 ARM 架构的),还可以添加
--cloud-kernel
使用轻量版内核。 - 不加
--password
选项会提示输入密码。
如果没有报错可以重启:
sudo shutdown -r now
约 30 秒后可以尝试 SSH 登录 installer
用户,密码与之前设置的相同。如果成功连接,可以按 Ctrl-A 然后再按 4 监控安装日志。安装完成后会自动重启进入新系统。
甲骨文云服务器:自动获取 IPv6
甲骨文云服务器:纯 IPv6 网络(无公网 IPv4)下安装方法
Introduction
This script is written to reinstall a VPS/virtual machine to Debian 10 Buster.
Should Work On
Virtualization Platform
- SolusVM/OpenStack/DigitalOcean/Vultr/Linode/Proxmox/QEMU KVM (BIOS boot)
- Oracle Cloud Infrastructure (UEFI boot)
- Google Cloud Compute Engine (Must manually configure the VPC internal IP and the gateway. UEFI boot with Secure Boot support)
- AWS EC2 & Lightsail (BIOS boot)
- Hyper-V & Azure (Generation 1 BIOS boot & Generation 2 UEFI boot)
Original OS
- Debian 8 or later
- Ubuntu 14.04 or later
- CentOS 7 or later
How It Works
- Generate a preseed file to automate installation
- Download the 'Debian-Installer' to the
/boot
directory - Append a menu entry of the installer to the GRUB2 configuration file
Usage
1. Download
Download the script with curl:
curl -fLO https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh
# for IPv6-only machines
curl -fLO --resolve 'raw.githubusercontent.com:443:2a04:4e42::133' https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh
or wget:
wget -O debi.sh https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh
2. Run
Run the script under root or using sudo:
chmod a+rx debi.sh
sudo ./debi.sh
By default, an admin user debian
with sudo privilege will be created during the installation. Use --user root
if you prefer.
3. Reboot
If everything looks good, reboot the machine:
sudo shutdown -r now
Otherwise, you can run this command to revert all changes made by the script:
sudo rm -rf debi.sh /etc/default/grub.d/zz-debi.cfg /boot/debian-* && { sudo update-grub || sudo grub2-mkconfig -o /boot/grub2/grub.cfg; }
