Download the JDBC Driver

Download the JDBC Driver for MySQL from http://mysql.spd.co.il/Downloads/Connector-J/mysql-connector-java-3.1.14.zip
Put the "mysql-connector-java-3.1.14-bin.jar" in

Solr Dir/example/lib

Configuring Solr to Use MySQL

Solr can be configured to connect to a MySQL Data base using the DataImportHandler. To do so first in

solrconfig.xml

(This file would be in

Solr Dir/example/conf

) add a new requestHandler which is handled by DIH (DataImportHandler).

 <requestHandler
 name
="/dataimport"
 

     class
="org.apache.solr.handler.dataimport.DataImportHandler"
>


<lst
 name
="defaults"
>


<str
 name
="config"
>

data-config.xml</str>



</lst>



</requestHandler>

Create a new file called data-config.xml in the same directory and configure the database connection and table schema to reflect your database structure.

Sample data-config.xml

<dataConfig>



<dataSource
 type
="JdbcDataSource"


   driver
="com.mysql.jdbc.Driver"


   url
="jdbc:mysql://SERVER/DATABASE"


   user
="USERNAME"
 

   password
="PASSWORD"
/>


<document
 name
="content"
>


<entity
 name
="node"
 query
="select node.nid AS nid,node_revisions.body AS body,node_revisions.title AS title from node,node_revisions where node.status = 1 and node.nid = node_revisions.nid and node.vid = node_revisions.vid"
>


<field
 column
="nid"
 name
="id"
 />


<field
 column
="body"
 name
="body"
 />


<field
 column
="title"
 name
="title"
 />


</entity>



</document>



</dataConfig>

The dataSource configuration attributes , query in entity tag and database fields must be modified to match your database structure. The Query given in the example is a simple Join of the drupal node and node revisions tables.

Now restart or start ApacheSolr using java -jar start.jar .

Hit the full-commit url (http://SERVER:PORT/solr/dataimport?command=full-import) and your website would start getting indexed.
