Install from Source (RedHat Enterprise Linux, CentOS, Scientific Linux, Fedora)

Preparation

Create a dedicated Opencast user.

useradd -d /opt/matterhorn opencast

Get Opencast source:

You can get the Opencast source code by either downloading a tarball of the source code or by cloning the Git repository. The latter option is more flexible, it is easier to upgrade and in general preferred for developers. The prior option, the tarball download, needs less tools and you do not have to download nearly as much as with Git.

Using the tarball:

Select the tarball for the version you want to install from https://bitbucket.org/opencast-community/matterhorn/downloads#tag-downloads

# Download desired tarball
curl -O https://bitbucket.org/opencast-community/matterhorn/...
tar xf develop.tar.gz
mv opencast-community-matterhorn-* /opt/matterhorn/

Cloning the Git repository:

git clone https://bitbucket.org/opencast-community/matterhorn.git
cd matterhorn
git tag   <-  List all available versions
git checkout TAG   <-  Switch to desired version

Switch to user opencast:

sudo su - opencast

Compile the source code:

cd /opt/matterhorn
mvn clean install -DdeployTo=/opt/matterhorn

Configure

Please follow the steps of the Basic Configuration guide. It will help you to set your hostname, login information, …

Running Opencast

Install Opencast start script and man-page for installations in /opt:

cd /opt/matterhorn/docs/scripts/init/opt
sudo ./install.sh

This will install the start script along with either a SysV-Init script or a systemd unit file.

Now you can start Opencast by running

sudo matterhorn --interactive

Browse to [http://localhost:8080] to get to the admin interface.

Run Opencast as Service

Usually, you do not want to run Opencast in interactive mode but as system service to make sure matterhorn is run only once on a system and is started automatically.

SysV-Init:

# Start Opencast
sudo service matterhorn start
# Autostart after reboot
sudo chkconfig --level 345 matterhorn on

Systemd:

# Start Opencast
sudo systemctl start matterhorn
# Autostart after reboot
sudo systemctl enable matterhorn
