With the external mode, Elasticsearch nodes are not embedded in eXo Platform server, eXo Platform connects to the external Elasticsearch node or cluster.
To use the external mode, you need to uninstall the embedded mode using this command:
./addon uninstall exo-es-embedded
The following plugins must be installed on each eXo Platform node:
Even if theoretically this addon should be compatible with any Elasticsearch version from 2.0, it has only been tested with the version 2.3. So we highly recommend to use Elasticsearch 2.3.x versions.
As for embedded mode, some parameters should be configured for the external mode through exo.properties file:
exo.es.search.server.url: The URL of the node used for searching.
exo.es.search.server.username: The username used for BASIC authentication on the Elasticseach node used for searching.
exo.es.search.server.password: The password used for BASIC authentication on the Elasticseach node used for searching.
exo.es.index.server.url: The URL of the node used for indexing.
exo.es.index.server.username: The username used for the BASIC authentication on the Elasticsearch node used for indexing.
exo.es.index.server.password: The password used for the BASIC authentication on the Elasticsearch node used for indexing.
You can find more details about the above parameters, default values and description in Properties reference table.
