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

cat <<EOF >/etc/cloud/cloud.cfg.d/56-custom-networking.cfg
network:
  version: 1
  config:
  - type: physical
    name: eth0
    subnets:
      - type: dhcp
      - type: dhcp6
EOF
reboot

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
