Setting up a new server

This page may be incomplete or not up to date.

Once provisioned, all servers are configured using automated tools such as Ansible/Terraform. But in some cases, certain initial setup is needed before these tools can run.

Preparing a server for Ansible

Change the password of the root user

# passwd
New password: <type password here>
Retype new password: <retype to confirm>

Import SSH publickeys

The keys can be found at https://github.com/sabnatarajan.keys. Download and put them in /.ssh/authorized_keys

On Ubuntu, importing is easy with the ssh-import-id-gh tool.

# ssh-import-id-gh sabnatarajan

Restart the SSH service: # systemctl restart ssh
