How to set solr/home in linux OS?

Question

I know how to configure solr.home by using Tomcat 6, but I don't know how to set solr.home by using Glassfish(V2.1). I have tried to set the solr.home in .profile as fellows:

export solr.home=/home/huenzhao/search/solr
export solr/home=/home/huenzhao/search/solr
export solr.solr.home=/home/huenzhao/search/solr
export JAVA_OPTS=$JAVA_OPTS -Dsolr.solr.home=/home/huenzhao/search/solr

and they all not work. The error is:

HTTP Status 500 - Severe errors in solr configuration. Check your log files for more detailed information on what may be wrong. If you want solr to continue after configuration errors, change: false in null ------------------------------------------------------------- java.lang.RuntimeException: Can't find resource 'solrconfig.xml' in classpath or 'solr/conf/', cwd=/home/huenzhao/search/glassfish/domains/domain1/config at org.apache.solr.core.SolrResourceLoader.openResource(SolrResourceLoader.java:194) at org.apache.solr.core.SolrResourceLoader.openConfig(SolrResourceLoader.java:162) at org.apache.solr.core.Config.(Config.java:100) at org.apache.solr.core.SolrConfig.(SolrConfig.java:113) at org.apache.solr.core.SolrConfig.(SolrConfig.java:70) at org.apache.solr.core.CoreContainer$Initializer.initialize(CoreContainer.java:117) at org.apache.solr.servlet.SolrDispatchFilter.init(SolrDispatchFilter.java:69) at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:273) at org.apache.catalina.core.ApplicationFilterConfig.setFilterDef(ApplicationFilterConfig.java:385) at org.apache.catalina.core.ApplicationFilterConfig.(ApplicationFilterConfig.java:119) at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:4498) at org.apache.catalina.core.StandardContext.start(StandardContext.java:5317) at com.sun.enterprise.web.WebModule.start(WebModule.java:353) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:989) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:973) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:704) at com.sun.enterprise.web.WebContainer.loadWebModule(WebContainer.java:1627) at com.sun.enterprise.web.WebContainer.loadWebModule(WebContainer.java:1232) at com.sun.enterprise.server.WebModuleDeployEventListener.moduleDeployed(WebModuleDeployEventListener.java:182) at com.sun.enterprise.server.WebModuleDeployEventListener.moduleDeployed(WebModuleDeployEventListener.java:278) at com.sun.enterprise.admin.event.AdminEventMulticaster.invokeModuleDeployEventListener(AdminEventMulticaster.java:1005) at

if you are running solr inside tomcat as a container you can specify the solr home inside the XML descriptor for this webapp. (my terminology for this is probably a little off).

I've got xml fragments for each solr instance I want to run and they specify their own local solr home directory inside the xml fragment. The fragments live at /conf/Catalina/localhost and each one manages a solr instance. This way I can have multiple solr instances on the same machine each with their own solr home variable.

The info is here: http://wiki.apache.org/solr/SolrTomcat

In paticular

Create a Tomcat Context fragment to point docBase to the $SOLR_HOME/apache-solr-1.3.0.war file and solr/home to $SOLR_HOME:

Symlink or place the file in $CATALINA_HOME/conf/Catalina/localhost/solr-example.xml, where Tomcat will automatically pick it up. Tomcat deletes the file on undeploy (which happens automatically if the configuration is invalid).
