# Debian Network Reinstall Script

[General description in English ↓](#introduction)

## VPS 网络重装 Debian 11 脚本

**暂不支持 Oracle Linux 作为原系统。创建新机器时请选择 Ubuntu 20.04 或 18.04 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。

## Introduction

This script is written to reinstall a VPS/virtual machine to minimal Debian 11.

## 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

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

### 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; }
