SOLR Tomcat Integration Tutorial

1. About SOLR

SOLR is a lucene-based Java search engine server. SOLR provides level search, hit highlighting, and supports multiple output formats (including XML/XSLT and JSON formats). It is easy to install and configure, and comes with an HTTP-based management interface. SOLR has been used in a number of large sites, more mature and stable. SOLR has packaged and expanded Lucene, so Solr basically follows the terms of Lucene. More importantly, the index created by SOLR is fully compatible with the Lucene search engine library. By properly configuring SOLR, some situations may require coding, and SOLR can read and use indexes built into other Lucene applications. In addition, many Lucene tools (such as Nutch, Luke) can also use the index created by SOLR.

2. Tomcat under SOLR installation configuration
Since SOLR is based on Java development, SOLR is well-deployed in both Windows and Linux, but since SOLR provides some shell scripts for testing and managing and maintaining more convenient shells, it is recommended to install Linux on production deployments. It can be used in Windows when testing.

The following is a description of the Linux under Installation configuration SOLR, similar to Windows.

wget Http://apache.mirror.phpchina.com/tomcat/tomcat-6/v6.0.16/bin/apache-tomcat-6.0.16.zip

Unzip Apache-tomcat-6.0.16.zip

MV Apache-tomcat-6.0.16/opt/tomcat

chmod 755/opt/tomcat/bin/*

wget http://apache.mirror.phpchina.com/lucene/solr/1.2/apache-solr-1.2.0.tgz

Tar zxvf apache-solr-1.2.0.tgz

method based on the current path
CP Apache-solr-1.2.0/dist/apache-solr-1.2.0.war/opt/tomcat/webapps/solr.war

Mkdir/opt/solr-tomcat

Cp-r apache-solr-1.2.0/example/solr//opt/solr-tomcat/

Cd/opt/solr-tomcat

/opt/tomcat/bin/startup.sh

In this case (without setting the SOLR.SOLR.HOME environment variable or jndi), SOLR looks for./SOLR, so you need to switch to/opt/solr-tomcat at boot time

based on environment variable Solr.solr.home

Add the following environment variable in the current user's environment variable (. bash_profile) or in/opt/tomcat/catalina.sh

Export java_opts= "$JAVA _OPTS-DSOLR.SOLR.HOME=/OPT/SOLR-TOMCAT/SOLR"

based on Jndi configuration

Mkdir–p/opt/tomcat/conf/catalina/localhost

Touch/opt/tomcat/conf/catalina/localhost/solr.xml, the contents are as follows:

<context docbase= "/opt/tomcat/webapps/solr.war" debug= "0" crosscontext= "true" >

<environment name= "Solr/home" type= "java.lang.String" value= "/OPT/SOLR-TOMCAT/SOLR" override= "true" />

</Context>

Access to the SOLR management interface HTTP://IP:PORT/SOLR
