Contents
Introduction
Everything on this page needs to be done as root, unless specified, so su to root.
sudo -i
Set hostname
hostnamectl set-hostname test0.mgk.ro reboot
Scaleway
If you're on a braindead platform like Scaleway, you might also need to disable this:
systemctl disable scw-set-hostname
Package management
Do not install recommended and suggested packages
cat <<EOT >/etc/apt/apt.conf.d/61norecommends APT::Install-Recommends "false"; APT::Install-Suggests "false"; EOT
Update the software
apt update && apt -y upgrade reboot
User management
Create a user (cloud computing)
useradd -c 'Aram Hăvărneanu' -G users -m -s /bin/bash -g staff aram passwd -l aram
Enable passwordless sudo for the staff group:
echo '%staff ALL=(ALL) NOPASSWD:ALL' > /etc/sudoers.d/91-staff-no-password
Fix the user created during installation (non-cloud)
usermod -a -G staff aram passwd -l aram
Enable passwordless sudo for the staff group:
echo '%staff ALL=(ALL) NOPASSWD:ALL' > /etc/sudoers.d/91-staff-no-password
SSH
For ssh access, use su to switch from root to the user and then add ssh keys.
su - aram # as a user mkdir -p .ssh echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJnkro8LT0TS+NTOIB787wfqIwv2VTmXXYsnsoVk71UE aram@horizon.local' >> .ssh/authorized_keys echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIC8dcfsqZJWTNTCfATbD6WiZyWoK3AiihynONRjCrtMw aram@oceanic.local' >> .ssh/authorized_keys echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIMRc0UWKrFpCv/EOUo2jpEQt+C/pa0tc1rUWKgjbKTp7 aram@edengate.local' >> .ssh/authorized_keys chmod 700 .ssh chmod 644 .ssh/authorized_keys
Install packages
For home installations you might want to install avahi.
apt install avahi-daemon
For development system you might want to install:
apt install -y git build-essential clang clang-format clang-tidy
