Installation d'Apache Solr sur Debian Jessie (pour Drupal 7)

Il semble assez courant d'utiliser le moteur d'indexation Apache Solr pour Drupal via la panoplie de module autour de Search API.

Pré-requis

Apache Solr en développé en Java, il nous faut donc installer la plateforme d'execution JRE (Java Runtime Environment).
