One time huge import from Mongo to Solr in Centos 7

1. Install libcurl
yum install curl-devel

2. Install libxml
yum install libxslt-devel

2.1 Make sure both mongo & mongodb php extensions are installed
pecl install mongo
pecl install mongodb
Add the following to php.ini if not already added :

3. Install solr php extension
pecl install -n solr

4. Enable solr extension
Add in php.ini and restart apache
sudo service httpd restart
php -m | grep solr

Make sure there are no errors, if there are then it can be related to the order in which files are loaded. In which case remove `` from php.ini and create a new file in /etc/php.d, possible 41-solr.ini such that it’s loaded at the end and add `` in that.

Confirm if that file is being used by php.ini by the following command
php -i | grep “.ini”

6. Download scripts from
Change the .ini file according to your mongo & solr connection settings.
Execute the following command to start the import from mongo to solr
php mongoSolrImporter.php -c mongoSolrImporter.ini

NOTE – The sample .ini file lists the field names in capitals, make sure to have the field name appropriate to your mongo collection. I have all the field-names in lower case in both mongo collection & solr document.

How to use Solarium (3.6.0) with Laravel 5.2

After hours of research falling into traps referring examples of different versions, finally managed to figure out the correct one.

1. Create `app/config/solr.php`


return array(
    'endpoint' => array(
        'key' => array(
            'host' => '',
            'port' => 8983,
            'path' => '/solr/',
            'core' => 'mycore'

2. Add the following code to HomeController

<?php namespace App\Http\Controllers;  use Illuminate\Support\Facades\Config;  use Solarium\Core\Client\Client;  use Solarium_Exception;  class HomeController extends Controller {      protected $client;          public function __construct()     {          $configSolr = Config::get('solr');          $this->client = new Client($configSolr);
public function index()
// create a ping query
$client = $this->client;
$ping = $client->createPing();
// execute the ping query
$result ='';
try {
$result = $client->ping($ping);
echo 'Ping query successful';
echo '<br?>';
} catch (Solarium_Exception $e) {
echo 'Ping query failed';
return $result;

Fix an existing Data Scraper

Client has already got the scraper built from me some time ago and now he required a code-revision for adding more features.

The software scrapes a forum website to find out all the threads a particular user is involved in (has replied to). All thread urls are then written to an output txt file.
