Till now we have seen how to install and configure Apache Solr, Now it is time to import your MySQL database into Solr for searching and indexing.

Edit solrconfig.xml file

Change directory to solr in tomcat6 using and edit solrconfig.xml
cd /var/lib/tomcat6/solr
vim conf/solrconfig.xml
And add following lines after <config> tag
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler"> 
    <lst name="defaults"> 
        <str name="config">data-config.xml</str> 
Next below in <lib> tags change directory path for apache-solr-dataimporthandler library to dist/ folder in apache-solr-3.6.2 which you downloaded while installation of Apache Solr.

Create data-config.xml file

Create data-config.xml file in conf/ folder and add below code.
    <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://" user="root" password="YOUR_DB_PASSWORD"/> 
            <entity name="id"  query="select * from students" > 
                <field column="id" name="id" /> 
               <field column="fullname" name="fullname" /> 
               <field column="first_name" name="first_name" /> 
                <field column="last_name" name="last_name" />            
Replace values appropriately with your database credentials and in fields section match column names in your columns in your table.

Edit schema.xml in conf/ folder and add below lines along with other field tags.
    <field name="id"  type="text_general"  indexed="true" stored="true"/> 
    <field name="fullname"  type="text_general"  indexed="true" stored="true"/>
