The $SOLR_HOME needs to include the solr directory under (e.g. /opt/solr/example/solr) otherwise
a 404 error occurs when requesting http://<host>:<port>/solr-example/admin/
=== Installing Solr instances under Tomcat ===
Assuming that Solr and its ''example'' are built, this is how to install the Solr example
as an instance under Tomcat.
- Copy the ''example/solr'' directory from the source to the installation directory like ''/opt/solr/example'',
herafter ''$SOLR_HOME''. Copy the .war file ''dist/apache-solr-*.war'' into ''$SOLR_HOME''
as ''solr.war''.
+ Copy the ''example/solr'' directory from the source to the installation directory like ''/opt/solr/example/solr'',
herafter ''$SOLR_HOME''. Copy the .war file ''dist/apache-solr-*.war'' into ''$SOLR_HOME''
as ''solr.war''.
The configuration file ''$SOLR_HOME/conf/solrconfig.xml'' in the example sets ''dataDir''
for the index to be ''./solr/data'' relative to the current directory - which is true for
running the Jetty server provided with the example, but incorrect for Tomcat running as a
service. Modify the ''dataDir'' to specify the full path to ''$SOLR_HOME/data'':
. {{{
- <dataDir>${solr.data.dir:/opt/solr/example/data}</dataDir>
+ <dataDir>${solr.data.dir:/opt/solr/example/solr/data}</dataDir>
}}}
The ''dataDir'' can also be temporarily overridden with the ''JAVA_OPTS'' environment variable
prior to starting Tomcat:
. {{{
- export JAVA_OPTS="$JAVA_OPTS -Dsolr.data.dir=/opt/solr/example/data"
+ export JAVA_OPTS="$JAVA_OPTS -Dsolr.data.dir=/opt/solr/example/solr/data"
}}}
Create a Tomcat Context fragment to point ''docBase'' to the ''$SOLR_HOME/solr.war'' file
and ''solr/home'' to ''$SOLR_HOME'':
{{{
<?xml version="1.0" encoding="utf-8"?>
- <Context docBase="/opt/solr/example/solr.war" debug="0" crossContext="true">
+ <Context docBase="/opt/solr/example/solr/solr.war" debug="0" crossContext="true">
- <Environment name="solr/home" type="java.lang.String" value="/opt/solr/example" override="true"/>
+ <Environment name="solr/home" type="java.lang.String" value="/opt/solr/example/solr"
override="true"/>
</Context>
}}}
Symlink or place the file in ''$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).
