Simple Nextcloud Installation on Raspberry Pi

This article was revised and updated on 27th May 2017.

The Raspberry Pi’s low power consumption makes it well suited to the role of always-on web server. This post describes how to install Nextcloud onto the Pi.  Nextcloud is an open source software package providing remote file sharing services, similar to Dropbox. But with Nextcloud, you retain ownership, security and control of the shared data. Nextcloud works well on a Pi 2 and Pi 3 but will run very slowly on a Pi 1.

The below procedure describes how to install Nextcloud version 12.0.0, the latest stable version at the time of writing (27th May 2017), but it should work for later/future versions too.

Simple Owncloud Installation on Raspberry Pi 2

The Raspberry Pi’s low power consumption makes it well suited to the role of always-on server. This post describes how to install Owncloud onto the Pi. Owncloud is an open source software package providing remote file sharing services, similar to Dropbox. But with Owncloud, you retain ownership, security and control of the shared data. Owncloud works well on a Pi 2 and Pi 3 but will run very slowly on a Pi 1.

Update 20th November 2016 – There is a newer version of this article. Please see Simple Nextcloud Installation on Raspberry Pi. Nextcloud was forked from ownCloud in June 2016. It now seems to have become the natural successor to Owncloud. I recommend using Nextcloud rather than Owncloud. This article remains on line because it might be helpful to existing Owncloud users, particularly the parts about upgrading and using external USB media.

UPDATE 16th July 2016 – Nextcloud was forked from Owncloud in June 2016. The procedure below can be used both for Owncloud and the initial release of Nextcloud (version 9.0.52). Thanks to Dan for this information.

My Raspberry Pi 2 was purchased from RS Components in the UK. It was installed with Raspbian “Jessie” (Debian 8) by applying the image “2016-02-09-raspbian-jessie.img” downloaded from the raspberrypi.org downloads page. The following procedure was then performed without any further pre-work (other than enabling ssh in the basic setup). Continue reading

Simple Picture Gallery on Raspberry Pi

This post describes how to create a simple photo gallery on the Pi, which can be shared over the internet with or without password protection. While not as polished as Flickr, Smugmug or similar services, it allows you to retain ownetship, control and security of the shared images. Continue reading

Simple Webcam on Raspberry Pi

The Raspberry Pi’s low power consumption makes it well suited to the role of always-on server. This post describes how to attach a simple webcam to a Raspberry Pi and have it take a snapshot every few minutes, and how to view the pictures on the web. Just like a traditional webcam.

My Raspberry Pi was purchased from New It in the UK. It was installed with Debian 7 (“Wheezy”) by applying the image “2014-01-07-wheezy-raspbian.zip” downloaded from the raspberrypi.org downloads page. The following procedure was then performed without any further pre-work (other than enabling ssh in the basic setup). Continue reading

Create a Basic Website on a Raspberry Pi

The Raspberry Pi is a small Linux computer designed to help children learn programming. Being a full Linux System, it can also be used as a server or as the basis for various projects. This post describes how to install Apache onto the Pi and set up a basic web site.

My Raspberry Pi was purchased from RS Components in the UK. It was installed with Raspbian “Jessie” (Debian 8) by applying the image “2017-04-10-raspbian-jessie-lite.img” downloaded from the raspberrypi.org downloads page, where it is described as “Minimal image based on Debian Jessie”. The following procedure was then performed without any further pre-work (other than enabling ssh in the basic setup). Continue reading

Huge Apache Error Log from Solaris 10 LicenseWatcher

Working on a client site recently, I noticed their Apache error log had grown to 32 Gb in size. The file was being written to at a rate of a quarter of a million lines a day, propelled by various cron jobs set up to run every 5 minutes. A PHP reconfiguration fixed the problem.

The box was a Solaris 10 system running “License Watcher“, and those messages was all coming from the License Watcher php code. Not genuine errors, just repeated diagnostics. I edited /usr/local/php/lib/php.ini and changed this line Continue reading
