Editer et configurer votre fichier de configuration apache en ajoutant les lignes suivantes :

AddDefaultCharset UTF-8
Options +MultiViews
<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteRule http-poll/ http://localhost:5280/http-poll/ [P]
</IfModule>

Pour terminer, il suffit de se connecter sur votre serveur, par exemple sur l'adresse : http://server.exemple.com/jwchat/

Vous pouvez vous créer une compte ou vous identifier. Par défaut, utiliser le Native Polling.

Editer le fichier /etc/ejabberd/ejabberd.cfg puis commenter la ligne avec “%” :

%{access, register, [{allow, all}]}.

Et décommenter en retirant “%” sur la ligne :

{access, register, [{deny, all}]}.

Pour lister les utilisateurs enregistrés :

ejabberdctl vhost localhost registered-users

Pour lister les utilisateurs connectés :

ejabberdctl connected-users

Pour sauvegarder la configuration :

ejabberdctl dump backup.txt

le fichier se trouvera dans /var/lib/ejabberd/backup.txt

Pour restaurer la configuration

ejabberdctl load backup.txt
