Hetzner server configuration

Please checkout https://keithtenzer.com/2019/10/24/how-to-create-a-rhel-8-image-for-hetzner-root-servers/ and learn how to create a RHEL8 image for Hetzner.

First have a look at config.txt and adjust it to your needs. Copy this repo to local system. Boot Hetzner in rescue mode. Upload RHEL file and config.txt to Hetzner via SCP.

Do in rescue mode:

installimage -a -c config.txt

Reboot afterwards.

Upload the whole repo via SCP to the fresh system in /root

Connect via ssh and root user to your system! Set all necessary environment variables.

export SSH_PORT=
export NEW_USER=
export TOOLS="git ansible @virt tmux cockpit-machines"
export RHN_USER=
export RHN_PASSWORD=
export PUBLIC_KEY=""

Finally excute the following script. It will configure:

• subscription for your system
• necessary repositories
• SSH port and relevant changes to firewalld and SELinux
• no RootLogin via SSH and public key authentication only
• a new user
• wheel group for the new user
• passwordless sudo
• authorized keys in new user's home/.ssh/ directory
• all tools set in TOOLS environment variable
• autostarting cockpit and libvirt

sh /root/hetzner-server-configuration/server-conf-files/configureServer.sh

Finished!

You can validate your configuration by connecting to your system with user $NEW_USER
You may want to expose cockpit by yourself :-)
