Download the apachesolr module from drupal.org, and put it in sites/all/modules:

http://drupal.org/project/apachesolr

download solr-php-client, version 22

http://code.google.com/p/solr-php-client/downloads/list

and uncompress it in the apachesolr module directory.

Ready to activate the module, but we will did not installed the Apache server, so the module will not work.
