Installing remote index

If users want to analyze WFS data (See Analyze and visualize data), an Elasticsearch <https://www.elastic.co/products/elasticsearch> instance can be installed next to the catalog.

Manual installation

Download Elasticsearch from https://www.elastic.co/downloads/elasticsearch and unzip the file.

cd es/config
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.4.2.tar.gz
tar xvfz elasticsearch-7.4.2.tar.gz

Manually start and stop Elasticsearch using:

elasticsearch-7.4.2/bin/elasticsearch

Then create the default index:

cd es
curl -X PUT http://localhost:9200/features -H "Content-Type: application/json" -d @config/features.json
curl -X PUT http://localhost:9200/records -H "Content-Type: application/json" -d @config/records.json
curl -X PUT http://localhost:9200/searchlogs -H "Content-Type: application/json" -d @config/searchlogs.json

Stop Elasticsearch using

elasticsearch-7.4.2/bin/elasticsearch stop

Install using Maven

Running from the source code, use Maven to download.

cd es
mvn install -Pes-download
mvn exec:exec -Des-start
curl -X PUT http://localhost:9200/features -H "Content-Type: application/json" -d @config/features.json
curl -X PUT http://localhost:9200/records -H "Content-Type: application/json" -d @config/records.json
curl -X PUT http://localhost:9200/searchlogs -H "Content-Type: application/json" -d @config/searchlogs.json

To stop Elasticsearch when using Maven, simply stop the process as Elasticsearch is started in foreground mode.

Check installation

Access Elasticsearch admin page from http://localhost:9200/.

Configure connection

Update Elasticsearch URL in `WEB-INF/config.properties`, add “es” to the “spring.profiles.active” in `WEB-INF/web.xml` to activate it and restart the application (see source file %sweb/src/main/webResources/WEB-INF/config.properties).
