Introduction

Everything on this page needs to be done as root, unless specified, so su to root. 

sudo -i

Cloud Init

If your install uses cloud-init (e.g. Amazon EC2) do the following:

Set hostname

echo 'preserve_hostname: yes' >/etc/cloud/cloud.cfg.d/55-preseve-hostname.cfg
echo 'eden.mgk.ro' >/etc/hostname 
reboot

Enable IPv6

Update the software =

dnf -y upgrade-minimal
reboot

Create a user

useradd -c 'Aram Hăvărneanu' -G wheel,users -m -s /bin/bash -U aram
passwd -l aram

Enable passwordless sudo for the wheel group: 

echo '%wheel ALL=(ALL) NOPASSWD:ALL' > /etc/sudoers.d/91-wheel-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 AAAAC3NzaC1lZDI1NTE5AAAAIANJ9BKKslS9Zqp1dRWL1nRiLmFp7nGvP06zPJ4L7cES aram@emerald.local' >> .ssh/authorized_keys
echo 'ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIJnkro8LT0TS+NTOIB787wfqIwv2VTmXXYsnsoVk71UE aram@horizon.local' >> .ssh/authorized_keys
chmod 644 .ssh/authorized_keys
