How do I setup Raspberry Pi

September 2019 ยท 4 minute read

Somehow I end up breaking my Raspberry Pi all of the time. Today it was the sudoers file that I modified using nano instead of visudo and voila - I cannot be root anymore. Another time I simply forgot my user’s password and apparently it’s impossible to login via ssh anymore (I don’t have spare physical screen and keyboard). So somehow it happens all of the time and I need to reimage SD card and setup everything from scratch. That’s the reason I’m writing this note - to future myself.

Prepare SD card

Download raspbian image

First thing to do is to visit official website and download latest Raspbian image.

Then, verify hashsum using shasum -a 256 (under macOS).

Extract image from the archive

Run Unarchiver or 7zip and extract .img from .zip.

Flush image to SD card

For that you need to know SD card disk number.

diskutil list
diskutil unmountDisk /dev/disk2
sudo dd bs=1m if=~/Downloads/Installs/2019-07-10-raspbian-buster-lite.img of=/dev/rdisk2 conv=sync

Then, when it will be automounted, create empty file with name “ssh” in /boot (that will be the only mounted device).

System setup


Now you can insert SD card to Raspberry Pi and turn it ON. I use network cable so I don’t need to care about WiFi setup. It’s much faster and much easier in my case.

ssh [email protected]
sudo raspi-config

Go to “Advanced” and “Expand filesystem” - this is a first thing to do before downloading updates. Let’s use all 32GB of the SD card instead of 2.2GB of the image we flushed.

Then I install log2ram and modify the limits using sudo vi /etc/log2ram.conf to have at least 200MB of log space available. This is done to preserve the SD card from frequent writes.

Now it’s a good idea to reboot to make use of log2ram.


I use some of the tricks described in security section. I mean changing the default user, using complex autogenerated password, restricting ssh access and things alike.

sudo adduser pihole
sudo adduser pihole sudo

Now it should be possible to reconnect on SSH with pihole user.

sudo deluser -remove-home pi
sudo vi /etc/sudoers.d/010_pi-nopasswd

Editing sudoers is required to disallow passwordless sudo for all users: just change NOPASSWD to PASSWD for your new user and save the file.

Also you may want to add use to group “video” so you will be able to read RaspberryPi temperature with command /opt/vc/bin/vcgencmd measure_temp. In order to do so, run sudo usermod -aG video <username>.

What I also usually do is I configure fail2ban in order to restrict ssh attempts with wrong password.

sudo apt install fail2ban
sudo cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
sudo vi /etc/fail2ban/jail.local

As for the last command - modifying the config - it’s just enough to find [ssh] section and set enabled = true and maxretry = 6.


It will be a good idea to install all possible updates

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get clean


Now when the base system is ready, we can install Pi-Hole using commands that you can find in official GitHub repository.

curl -sSL | bash

After going through configuration steps, everything what is left to do is to setup static DNS in your router.

I’d like to state that Pi-Hole by itself is not enough for your privacy and security, but it’s a good start.


In order to install kanboard on raspberry pi, first install php with friends

sudo apt-get install php php-gd php-mbstring php-xml php-sqlite3

and git if it’s not installed sudo apt-get install git.

After this, extract fresh Kanboard in the www/ directory:

cd /var/www/html/
sudo git clone
cd kanboard
sudo git checkout v1.2.12
cd ..
sudo chown -R www-data:www-data kanboard/data
service apache2 restart

For kanboard I usually also install kanboard tdg plugin as a task-management system.

cd kanboard/plugins
sudo wget
sudo unzip -d TdgImport

Ultimately, run

sudo service apache2 restart

and navigate to http://ip-of-rpi/kanboard/, login with admin:admin to kanboard and configure users and projects.
