Why am I having trouble running the Red5 Pro server as a service?
If updating from a previous release and you intend to run Red5 Pro Server as a Service, the commons-daemon path needs to be updated or created in the /lib/systemd/system/red5pro.service file. This change is necessary as of release 5.7.0. See here for complete instructions: Defining Red5 Pro As a Service.
