Raspberry Pi (4) Basic Setup

This manual describes how to setup a Raspberry Pi with a little bit of sane default configs.

This is a revamped version of this gist, this time focusing on the setup of the Pi only.

Install and run Raspbian on an SSD

Transport security (i.e. TLS)

Convert and merge audio files for kid's audio player

Nextcloud on Raspberry Pi 3 Setup

Tip

There is a new and up-to-date version of this gist (with focus on the Raspi setup part): https://gist.github.com/ronau/462731589c44f91bb4a3b7d30d277ecf

This manual describes how to setup a Raspberry Pi 3 with nginx, PHP 7.0, MariaDB and use it as a Nextcloud server. Strong TLS encryption with Let's Encrypt certificates is also used. Of course, Owncloud can be used instead of Nextcloud. As of February 2017, the installation instructions are basically the same.
