Solr maven template

Alastair Porter, 2013

This sample POM provides a simple way to develop a Solr server and then deploy it to a servlet container.

Development

To quickly set up a solr server, run

mvn jetty:run-war

Access the solr server at http://localhost:8080

Solr configuration is in the solr/ directory. Because the solr.home variable is not set, Solr will default to this. If you want to change the value of solr.home you can do it like this:

mvn -Dsolr.solr.home=myhome jetty:run-war

Add custom Solr components to src/main/java as you would in any other maven project. These will be compiled into the war file.

Deployment

If you want to deploy to a servlet container, run

mvn package

to create a war file in target/

When running in a servlet container you must configure the location of solr.home. For Tomcat there are a few ways of doing this (from http://wiki.apache.org/solr/SolrTomcat)

1. add

   JAVA_OPTS="$JAVA_OPTS -Dsolr.solr.home=/opt/solr/example"

to $CATALINA_HOME/bin/setenv.sh and deploy through webapps/ as usual.

2. Configure a Context fragment

   cp tomcat-context.xml $CATALINA_HOME/conf/Catalina/localhost/solr.xml

and edit the solr/home <Environment> value. Note that you can set up as many different contexts as you want with different solr/home values, each using the same solr.war
