# Debian Network Reinstall Script |
|
|
|
## 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 (with `--force-efi-extra-removable`; UEFI boot) |
|
* Google Cloud Compute Engine (manually set the VPC internal `--ip`, `--netmask`, `--gateway`; UEFI boot) |
|
* AWS EC2 & Lightsail (BIOS boot) |
|
* Hyper-V **but not Azure!** (Generation 1 BIOS boot & Generation 2 UEFI boot) |
|
|
|
### Original OS |
|
|
|
* Debian 8/9/10 |
|
* Ubuntu 14.04/16.04/18.04/20.04 |
|
* CentOS 7/8 |
|
|
|
## How It Works |
|
|
|
1. Generate a preseed file to automate installation |
|
2. Download the 'Debian-Installer' to the `/boot` directory |
|
3. Append a menu entry of the installer to the GRUB2 configuration file |
|
|
|
## Usage |
|
|
|
curl -fLO https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh && sudo sh debi.sh <OPTIONS> |
|
|
|
## Available Options |

|
|
* `--ip <string>` Disable the auto network config (DHCP) and configure a static IP address, e.g. `10.0.0.2`, `1.2.3.4/24`, `2001:2345:6789:abcd::ef/48` |
