By default, Jive installs and configures using the root context, for example http://yourcommunity.com. This is the recommended configuration and default installation behavior, but non-root contexts such as http://yourcommunity.com/community are also supported. To use a non-root context, you need to set an environmental variable that changes default installation behavior.
appadd --verbose sbs
export JIVE_NO_DEFAULT_APP=1
apprm sbs
appadd --context-path=community community
apprm removes the existing installation of Jive while retaining the database. appadd creates the new application instance. In this case, the context path would be the text to appear after the root URL (http://yourcommunity.com/community) and the argument community would be the name of the directory created in /usr/local/jive/applications/.
appadd --auto-port --context-path=sbs1 sbs1
appadd --auto-port --context-path=sbs2 sbs2
auto-port is aware of existing installations and will stagger the ports to allow multiple instances on a single server. This is useful for testing Jive, but note that single-server deployments are not recommended or supported for production.
For more about appadd see the appadd command reference.
