Installing the platform daemon

To reinstall the platform daemon on a Linux N4Supervisor for a particular version of Niagara 4 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 Niagara 4 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 for executing this file are:

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-4.n.nn/install# bash install_service.sh

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