Configuration and Installation of apache-solr and tomcat on your Drupal site

The Following are the steps which you will follow for the successful configuration of apache-solr and tomcat on your drupal site.

Download the apachsolr module from http://drupal.org/project/apachesolr and place it in your modules folder. In my case I placed it in sites/all/modules/apachesolr.

Download the SolrPhpClient from http://code.google.com/p/solr-php-client/downloads/list and placed inside the apachesolr module. In my case I placed it in sites/all/modules/apachesolr/SolrPhpClient.

Enable the Apache Solr Framework and Apache Solr Search modules.

Download the apache-solr from http://mirror-cybernet.lums.edu.pk/pub/apache//lucene/solr/1.4.1/ and place it any where you want but outside from your drupal site. In my case I placed it in C:\apache-solr-1.4.1.

Download the apache tomcat from http://tomcat.apache.org/download-70.cgi and extract it to the folder of your liking. In my case I placed it in C:\apache-tomcat-7.0.14.

Download the jdk from http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u25-download-346242.html and install it.

Rename the schema.xml, solrconfig.xml and protwords.xml to schema.bak, solrconfig.bak and protwords.bak respectively in apache-solr\example\solr\conf folder. In my case C:\apache-solr-1.4.1\example\solr\conf.

Copy the schema.xml, solrconfig.xml and protwords.xml from the apachesolr module folder and paste it in the apache-solr\example\solr\conf folder. In my case I copied the files form sites\all\modules\apachesolr and pasted in C:\apache-solr-1.4.1\example\solr\conf.

Copy the apache-solr-1.4.1.war from apache-solr\dist and paste it in apache-tomcat\webapps folder and rename it to solr.war. In my case I copied the file from the C:\apache-solr-1.4.1\dist and pasted it inside the C:\apache-tomcat-7.0.14\webapps and renamed it to solr.war.

Set the JAVA_HOME environmental variable by running the command “set JAVA_HOME=path/to/your/jdk”. In my case I ran the command “set JAVA_HOME= C:\program files\java\jdk1.6.0”.

Open the command prompt and go to the folder of apache-tomcat/bin and type startup and press enter to start the tomcat.


Then type the shutdown and press enter to stop the apache-tomcat.

This will unpack the war file resulting in the folder apache-tomcat/webapps/solr. In my case C:\apache-tomcat-7.0.14\webapps\solr.

Open the web.xml file from apache-tomcat\webapps\solr\WEB-INF and uncomment the section specifying the solr/home environment variable and set its value to the path of your apache-solr example application folder. In my case I opened the file from C:\apache-tomcat-7.0.14\webapps\solr\WEB-INF and did the following changes.


solr/home
C:/apache-solr-1.4.1/example/solr
java.lang.String



Open the commands prompt and go to the folder apache-solr/example and type “java –jar start.jar” and press enter to run the jdk. In my case look at the following image.

Now start the apache-tomcat as defined above in this document.

You can access the solr administration interface now at http://localhost:8080/solr/admin/.

Go to the path admin/settings/apachesolr of your drupal site and enable the make apache solr search the default under the advance configuration.

The synonyms.txt file is in apache-solr/example/solr/conf folder. In my case C:\apache-solr-1.4.1\example\solr\conf. Open the file and enter some words just like Television and TV and save the file.

Then go to your drupal site and run the cron to send the contents form your drupal site to the apache-solr search.

Then restart the jdk so that changes to the synonyms.txt file take affects.

Then search for those specific terms you will see the results.

Note: Remember to run the cron every time you add some contents to your drupal site so that it makes searchable for apache-solr search.
Now your site is ready for apache-solr search. If you get some errors or your search does not work then follow these steps carefully may be you have missed a step.
