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).

  name="/dataimport" 
     class="org.apache.solr.handler.dataimport.DataImportHandler">
     name="defaults">
       name="config">data-config.xml>
    >
  >

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

>
	 type="JdbcDataSource"
   driver="com.mysql.jdbc.Driver"
   url="jdbc:mysql://SERVER/DATABASE"
   user="USERNAME" 
   password="PASSWORD"/>
	 name="content">
         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">
             column="nid" name="id" />
             column="body" name="body" />
             column="title" name="title" />
        >
    >
>

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.
