.... Work in progress ....
Currently there is one main Solr instance installed in the DDB-Dev-Network: on ddb-di-05. This instance serves as the main search server for the develop and master backend deployments.
These instructions are only for updating this instance. Various prerequisites to running a solr instance are not covered as they have already been set up on this server.
To update this instance the following steps should be performed:
Download the new Solr version
wget https://mirror.synyx.de/apache/lucene/solr/X.Y.Z/solr-X.Y.Z.tgz
Check integrity of downloaded file
wget https://downloads.apache.org/lucene/solr/X.Y.Z/solr-X.Y.Z.tgz.sha512 sha512sum solr-X.Y.Z.tgz
Unpack new Solr version in /data/ddb/tools/solr
cd /data/ddb/tools/solr tar -xvzf ~/solr-X.Y.Z.tgz
Copy extra libs to Solr web-app folder
cd /data/ddb/tools/solr/solr-X.Y.Z/ cp dist/*.jar ./server/solr-webapp/webapp/WEB-INF/lib/ cp contrib/extraction/lib/*.jar ./server/solr-webapp/webapp/WEB-INF/lib/ cp contrib/analysis-extras/lucene-libs/*.jar ./server/solr-webapp/webapp/WEB-INF/lib/
Link custom libs from DDB Cortex
cd ./server/solr-webapp/webapp/WEB-INF/lib/ ln -s /data/ddb/Cortex/lib/SolrIndexServer.jar ln -s /data/ddb/Cortex/lib/solr-ocrhighlighting.jar
Stop running Solr server
service solr stop
