Installing the platform daemon

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

So the main reasons you will be executing this file are either:

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

You need to be acting as root to accomplish this task. The first step to installing a particular version's platform daemon is to change to the target release’s install directory:

root@<host>:/usr/bin# cd <targetNiagaraReleaseDirectory>/install

Then, you issue the “install_service.sh” command. For example, if installing the platform daemon from opt/Niagara/Niagara-3.4.25/install:

root@<host>:/opt/Niagara/Niagara-3.4.25/install# bash install_service.sh

The platform daemon (service) will be installed, but not started. See Starting the platform daemon.
