Installation from Source
These guides will help you to build Opencast, including all necessary third party tools. This method will most likely work on all Unix-like systems.
Building on most other Unix-like operating systems should be very much alike.
Installation from Repository
There is an RPM repository available for some operating systems. It provides packages containing pre-configured and pre-built Opencast installations.
Installation Across Multiple Servers
For production systems, it is recommended to install Opencast across multiple servers to separate the processing, management and presentation layer, so that, for example, even if the processing layer is under full load, users can still watch recordings unaffected since the presentation layer is running on a separate machine.
