VPS 网络重装 Debian 12 脚本
Debian Network Reinstall Script
General description in English ↓
VPS 网络重装 Debian 12 脚本
暂不支持 Oracle Linux 作为原系统。创建新机器时请选择 Ubuntu 系统模板。
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 <新系统用户密码>
--bbr
开启 BBR--ethx
网卡名称使用传统形式,如eth0
而不是ens3
--cloud-kernel
安装占用空间较小的cloud
内核,但可能会导致 UEFI 启动的机器(如 Oracle、Azure 及 Hyper-V、Google Cloud 等)VNC 黑屏。BIOS 启动的普通 VPS 则没有此问题。- 默认时区为 UTC,添加
--timezone Asia/Shanghai
可使用中国时区。 - 默认使用 Debian 官方 CDN 镜像源(deb.debian.org),添加
--china
可使用阿里云镜像源。
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。
Oracle 自动获取 IPv6
Oracle 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 minimal Debian 10/11/12.
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; }
