pi-gen-baselite

Files to create a base raspbian headless server using pi-gen-utils

This repo is useful as a test for generating an image using the pi-gen-utils package and pi-gen. It is also useful as a starting point for creating your own headless server. It will work on any pi though, in general, servers that are used in production should be pi3B+ or pi4 as the older pis can run in to performance issues under real load.

The repo creates a Raspbian Lite image with some minor tweaks that make it a good basic headless server. The tweaks are:

  • user/password is server/server
  • SSH is enabled by default
  • If a file called netcfg.txt with dhcpcd.conf lines is placed in /boot/ those lines will be appended to dhcpcd.conf so that the pi boots with a static IP address/gateway/dns as specified in the file

Dependencies

Generally speaking pi-gen works better in a docker environment. In the non-docker world failures can result in broken setups that are usually, but not always, fixed by logging out. In the docker version you just have a dead docker image to delete

Usage

cd /path/to/pi-gen/projects
git clone https://github.com/RPi-Distro/pi-gen.git
git clone https://github.com/FrancisTurner/pi-gen-utils.git
git clone https://github.com/FrancisTurner/pi-gen-baselite.git

sudo cp pi-gen-utils/*.sh /usr/local/bin
cd pi-gen-baselite
setuppigen.sh
cd ../pi-gen
build-docker.sh # or build.sh if you don't want to use docker

Pi-gen creates an image in pi-gen/deploy/

cp deploy/image*serverpi-lite* /some/where/useful/
cd -
restorepigen.sh

Burn pi image - using tool of choice e.g. Balena Etcher ( https://www.balena.io/etcher/ )

Edit samplenetcfg.txt and save to the boot partition on the newly flashed SD card as netcfg.txt. Or alternatively use the nifty netcfg generator page here - https://francisturner.github.io/gencfg.html

Notes:

  • You may need to eject and reinsert the SD card for your OS to correcly mount the newly created partition(s).
  • If you are flashing from a windows machine, ignore suggestions to format the new drive when you reinsert the SD card
  • Creating a netcfg.txt file is optional as without it the pi will query for a DHCP address, but it is strongly recommended because otherwise it can be tricky to figure out how to connect to your server and the server address may change over time, which is usually a bad thing.

Optionally create a wifi profile wpa_supplicant.conf in the boot partition following these instructions - https://www.raspberrypi-spy.co.uk/2017/04/manually-setting-up-pi-wifi-using-wpa_supplicant-conf/. If you are using the wifi then you will probably need to specify a wlan0 interface in netcfg.txt instead of/as well as the eth0 one.

eject the SD card, stick it in the pi, connect network cable and power the pi on

wait a minute or so for the pi to boot (check by pinging its IP address e.g. 192.168.1.250) then ssh to it as user server password server. Change the password and set up whatever you need on it (i.e. your preferred web server, email etc.)

Once you've checked that the image you've just built works, copy the files to your own project and edit/add more as required

Sample Image

In case you want to live dangerously and trust an image created by some random stranger on the internet here is a recent version of the image you can download to burn on your SD-card - http://raspbian.devtru.st/files/serverpi-lite.zip
