Configuration examples for distributed mode installation on Linux

Overview

The following section provides some examples of how to configure each variable in the configuration.conf file for different distributed installation scenarios and which installation command to run on a particular machine:

Scenario A

imaging-services, imaging-viewer, dashboards and analysis-node components each on dedicated machines (machines 1, 2, 3 and 4) and an additional analysis-node component to load balance (machine 5):

Install command:

./cast-imaging-install.sh imaging-services

configuration.conf:

IMAGING_SERVICES_HOSTNAME=machine1.corp.domain.com
IMAGING_VIEWER_HOSTNAME=
