Install from Repository (Fedora)
There is an RPM software repository available for RedHat-based Linux distributions provided by the University of Osnabrück. This repository provides preconfigured Opencast installations, including all 3rd-Party-Tools. Using this method, you do not have to compile the software by yourself.
It is also interesting for developers as all dependencies for Opencast usage, testing and development are provided by the RPM repository.
For Fedora usually the latest two versions are supported, meaning that the support is dependent on the status of the
Fedora release. For architectures, only
x86_64 is supported. 32bit architectures are not supported.
Before you can start you need to get an account for the repository. You will need the credentials that you get by mail
after the registration to successfully complete this manual. The placeholders
are used in this manual wherever the credentials are needed.
First you have to install the necessary repositories so that your package manager can access them:
Add matterhorn repository:
cd /etc/yum.repos.d curl -O http://repo.virtuos.uos.de/matterhorn-testing.repo \ -d 'version=$releasever' -d os=fc \ -u [your_username]:[your_password]
Add RPMfusion repository:
dnf install --nogpgcheck \ http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm \ http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonf
This step is optional and only recommended for those who want to build Opencast from source. If you install Opencast from the repository, all necessary dependencies will be installed automatically.
You can install all necessary 3rd-Party-Tools for matterhorn like this:
sudo dnf install opencast20-third-party-tools
sudo dnf install ffmpeg qt_sbtl_embedder tesseract mediainfo
Install Apache ActiveMQ
The Apache ActiveMQ message broker is required by Opencast since version 2.0. It does not necessarily have to be installed on the same machine as Opencast but would commonly for an all-in-one system. ActiveMQ is available from the Opencast RPM repository as well and can be installed by running:
dnf install activemq-dist
A prepared configuration file for ActiveMQ can be found at
after Opencast itself has been installed and should replace
/etc/activemq/activemq.xml. For an all-in-one
installation the following command should suffice:
sudo cp /usr/share/matterhorn/docs/scripts/activemq/activemq.xml /etc/activemq/activemq.xml
ActiveMQ should be started before starting Opencast.
More information about how to properly set up ActiveMQ for Opencast can be found in the message broker configuration documentation.
For this guide,
opencast20 is used as placeholder for the package name. It will install the latest version of the
Opencast 2.0.x branch. If you want to install another version, please change the name accordingly.
Notice: Since the name
matterhornwas dropped between version 1.6 and 2.0, old packages were named
For a basic installation (All-In-One) just run:
sudo dnf install opencast20
This will install the default distribution of matterhorn and all its dependencies, including the 3rd-Party-Tools.
Now you can start Opencast:
sudo systemctl start matterhorn.service
While Opencast is preconfigured, it is strongly recommended to follow at least the Basic Configuration guide. It will help you to set your hostname, login information, …
While the basic installation will give you an all-in-one Opencast distribution which is nice for testing, you might want to have more control over your system and deploy it over several machines by choosing which parts of Opencast you want to install. You can list all Opencast packages with:
dnf search opencast
This will list four kinds of packages:
opencastXX is the package that was used for the basic installation. It represents a default Opencast
distribution. This is what you would get if you built Opencast from source and do not change any options.
opencastXX-distribution-... packages will install preconfigured Opencast distributions. Have a look at
the Opencast Distribution section below for more information about the different distributions.
opencastXX-profile-... are the Opencast profiles from the main pom.xml. Each profile keeps track of a
couple of modules. You should only install these if you know what you are doing.
opencastXX-module-... are the Opencast modules itself. It should only be necessary to install these
directly in special cases. And you should only do that if you know what you are doing.
Normally you would either install the main package or a distribution package.
Pre-built Opencast Distributions
The following list provides an overview of the currently available pre-built Opencast distributions. Each distribution should keep track of all its dependencies.
Admin Opencast distribution
Install this package for an Opencast admin server. On this server, the Administrative services are hosted. You would usually select this package for one node if you are running Opencast across three or more servers.
Admin/Worker Opencast distribution
Combined Admin/Worker Opencast distribution. This will install both the modules and profiles for the Administrative Tools and the Worker. This package is targeted at medium-sized installations, where you want to separate the "backend" server that the admin accesses from the "frontend" server that the viewers use.
Default Opencast distribution
This is the default package containing all 3 main profiles (Admin, Worker, Engage) in one. This installation is only recommended if you do not have many videos that you want to ingest and you do not expect many viewers. This is perfect for a first test and to get an impression of Opencast, as it works out of the box and does not need much configuration.
Engage Opencast distribution
This is the package for the Opencast Engage Modules, which are the front-end to the viewer of your videos. It is always highly recommended to keep these separated from the rest of your system.
Worker Opencast distribution
This is the worker package that contains the modules that create the most CPU load (encoding, OCR, etc). So it is recommended to deploy this on a more powerful machine.
Sometimes you want to uninstall Opencast. For example to do a clean reinstall. You can do that by executing:
sudo dnf remove 'opencast*'
This will not touch your created media files or modified configuration files. If you want to remove them as well, you have to to that by yourself.
# Remove media files sudo rm -rf /srv/matterhorn # Remove configuration files sudo rm -rf /etc/matterhorn # Remove system logfiles sudo rm -rf /var/log/matterhorn
