# Setup Clean Debian OS for Your (Cloud) VPS |
|
|
|
## Step 1. Preparation |
|
|
|
- A clean normally running true virtualization (e.g. KVM) VPS with GRUB2 and VNC access. This script have been tested on SolusVM KVM VPS & Alibaba Cloud ECS with Debian 8/9 & Ubuntu 16.04/18.04. |
|
- Then check `/etc/default/grub` with your preferred editor (e.g. `nano` or `vi`). |
|
- Set `GRUB_DEFAULT` to `debian-netboot-installer` select the installer to boot automatically after timeout. |
|
- Make sure there's reasonable number for `GRUB_TIMEOUT` **timeout**. You can just set `GRUB_TIMEOUT=30` which will be fine. |
|
- Make sure there's **no** `GRUB_HIDDEN_TIMEOUT_QUIET` and `GRUB_HIDDEN_TIMEOUT`. **Just delete them.** |
|
|
|
Install dependencies: |
|
|
|
``` |
|
sudo apt update && sudo apt -y install ca-certificates whois |
|
``` |
|
|
|

|
|
|
Replace following `<OPTIONS>` with your options. |
|
|
|
``` |
|
sudo sh -c "$(wget -qO- https://github.com/brentybh/debian-netboot/raw/master/netboot.sh)" -- <OPTIONS> |
|
``` |
|
|
|
**Remember** to enter your current user's password for `sudo` (if need) and then enter the new user's password (if not specified by `-p`). |
|
|
|
### All Options |
|

|
- `-fqdn debian` FQDN including hostname and domain. Priority: `-fqdn` option > rDNS > `debian` as default. |

|
- `-crypto` Full disk encryption (Can't be fully automated at current time. Need VNC connection to go through the steps) |
|

|
- `-cidr 255.255.255.0` Netmask for manual network configuration |
|
- `-gw 192.168.1.1` Gateway for manual network configuration |
|
- `-ns "8.8.8.8 8.8.4.4"` DNS for manual network configuration |
|
- `-add "ca-certificates curl fail2ban openssl whois"` Include individual additional packages to install |

|
- `-dry-run` Generate `preseed.cfg` and save to current dir but don't actually do anything |
|
|
|
### Chinese Special |
|
|
|
If `-c CN` is used, Chinese Special options will be setup for good connectivity and experience against GFW. |
|
|
|
- Default archive mirror is `https://chinanet.mirrors.ustc.edu.cn/debian`. |
|
- Default security mirror is `https://chinanet.mirrors.ustc.edu.cn/debian-security`. |
|
- Default time zone is `Asia/Shanghai`. |
|
- Default NTP server is `cn.ntp.org.cn`. |
|
- Default DNS is `156.154.70.5 156.154.71.5`. |
|
- All custom settings will override above defaults. |
|
|
|
## Step 3. Entering Debian Installer |
|
|
|
- Keep your SSH connection and **open VNC console** on your Provider's control panel. |
|
- `sudo reboot` with your SSH and the VM should **reboot**. |
|
- Switch to your VNC window **quickly**. You should enter the **GRUB selection menu** now. |
|
- If you've configured correct `GRUB_DEFAULT`, it should be booted into installer automatically after timeout. |
|
- Or, use your keyboard to **select** `New Install` and **enter** it. Also, **be quick**, just do not miss the `GRUB_TIMEOUT` timeout you've set. |
|
- Finally, you should see the screen of Debian Installer now. It will setup all things automatically and reboot when complete.
