Installing the platform daemon

To reinstall the platform daemon on a Linux AxSupervisor for a particular version of NiagaraAX you will have to execute the script 'install_service', found in the Niagara "install" directory. It is not necessary to execute this script after a successful NiagaraAX installation, as that process will automatically install the platform daemon.

Prerequisites:

You need to be acting as root to accomplish this task.

The main reasons you would execute this file are either:

You have accidentally broken your Niagara environment and you want to repair it.
You have two versions of Niagara installed on your platform, and you want to change which platform daemon is started/controlled by '/usr/bin/niagaradctl’.

Perform the following steps:

To change to the target release’s install directory, type the following:

root@<host>:/usr/bin# cd <targetNiagaraReleaseDirectory>/install
To issue the “install_service.sh” command, type the following:

root@<host>:/opt/Niagara/Niagara-n.n.nn/install# bash install_service.sh

The platform daemon (service) is installed, but not started. See “Starting the platform daemon”.
