Liferay integration with solr 

Configure solr with Tomcat 7 

Step -1 

-  Download Solr from apache website. Here we are using solr 4.*.*.(solr-4.3.1.tgz)

-  Download tomcat from apache website(apache-tomcat-7.0.75.zip).

-  Create a  folder called "solr".

-  Unzip both files on solr folder.(  tar -xvf yourfile.tar)

-  Copy solr<version>.war from <extracted_solr>\dist 

    to <extracted_tomcat>\webapps and rename solr<version>.war to solr.war.

-  Copy all jars in <extracted_solr>\example\lib\ext  to <extracted_tomcat>\lib.

      Change the port to 8006

         <Server port="8005" shutdown="SHUTDOWN">

             Change ajp port to 8008

         <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

-  Change the port to 8983  in server.xml file of tomcat . (in different instance no need for this step)

-  Start the tomcat.

-  Check New folder names solr would be available in webapps.

-  Shutdown the tomcat.

-  Modify web.xml located at <extracted_tomcat>\webapps\solr\WEB-INF

         Uncomment below entry and update the path for solr\home.

      <env-entry>  <env-entry-name>solr/home</env-entry-name>   <env-entry-value>    <extracted_solr>C:/Solr/solr-4.3.1/example/solr</env-entry-value> <env-entry-type>java.lang.String</env-entry-type></env-entry>

- Start the tomcat and access the below URL.

      http://[IP ADDRESS]:[PORT]/solr or  http://localhost:[PORT]/solr

Step-2:

Setup solr-web plugins in liferay :

*  Download the solr web from liferay market place (Liferay Solr 4 Search Engine.lpkg) .

*  Copy the solr-web war file to deploy folder of liferay-server

*  After solr-web  plugin is deployed in Liferay, stop Liferay Tomcat server.

-  Go to <Liferay>/tomcat-7.0.27/webapps/solr-web/WEB-INF/conf directory.

-  Copy and replace schema.xml file to <extracted_solr>example/solr/collection1/conf directory on         solr server.

* Go to < liferay>/tomcat-7.0.42/webapps/solr4-web/WEB-INF/classes/ 

    Edit solr.properties file to update  with property server.http.url

    And value should be< solr-ip>:8983/solr

* Edit the solrconfig.xml file and update the values as below 

     <extracted_solr>example/solr/collection1/conf directory on Solr Server.

        <autoCommit> 

             <maxTime>10000</maxTime> 

            <openSearcher>true</openSearcher> 

     </autoCommit>

*  Creare the log4j.properties file in C:\Solr\apache-tomcat-7.0.75\lib and add the below properties

    #  Logging level

       log4j.rootLogger=INFO, file, CONSOLE

       log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender

   #log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout

     log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x \u2013 %m%n

   #- size rotation with log cleanup.

    log4j.appender.file=org.apache.log4j.RollingFileAppender

    log4j.appender.file.MaxFileSize=4MB

    log4j.appender.file.MaxBackupIndex=9

   #- File to log to and log format

    log4j.appender.file.File=C:\\Solr\\apache-tomcat-7.0.75\\logs\\solr.log

    log4j.appender.file.layout=org.apache.log4j.PatternLayout

log4j.appender.file.layout.ConversionPattern=%-5p - %d{yyyy-MM-dd HH:mm:ss.SSS}; %C; %m\n

    log4j.logger.org.apache.zookeeper=WARN

- After above changes are done, first start the Solr Tomcat Server after start Liferay Tomcat server.

- When Liferay Server starts successfully, follow below steps,

     -> Login with admin user

     -> Go to the Control Panel > Server > Server Administration.

     -> Click on Execute Button beside Reindex all search indexes.
