"Nicht autorisiert: Die Anfrage, die Sie vorgenommen haben, erfordert Authentifizierung. (HTTP 401)" auf Fiware Horizon

Question

Ich bin neu bei FIWARE. Auf meinem Ubuntu 16.04 habe ich Fiware's KeyRock eingerichtet, eine Kombination aus OpenStack Keystone Identity Management und Horizon Dashboard. Ich habe this Guide verwendet, um alles einzurichten.

Nach der Installation von Keystone (was eine RESTful API ist), habe ich curl verwendet, um HTTP-Anfragen zu senden und alles funktioniert gut, d. H. Ich kann these Befehle auf dem Keystone-Server mit curl ausführen.

Allerdings, wenn ich im openstack_dashboard Verzeichnis mit sich Django Horizon auf dem gleichen Server mit dem Referenzprojekt auszuführen:

sudo tools/with_venv.sh python manage.py runserver 0.0.0.0:8000,

Horizon Server startet ohne Fehler, aber wenn ich Zugriff auf sie über den Browser, ich erhalte die folgende Fehlermeldung:

A server error occured. Please contact the administrator 

Auf der Keystone-Server-Konsole, erhalte ich folgende Fehlermeldung:

Ich bin eine GET-Anfrage über den Browser zu senden, aber der Keystone-Server eine POST-Anforderung empfängt, wie in seinem Konsolenausgabe. Ich verstehe nicht, warum das so ist.

Answer 1

Es sieht so aus, als ob der Horizon Server die Anmeldeinformationen nicht überprüfen kann.

Im Falle von Fiware würden Sie diesen Fehler auf dem Horizon Server erhalten, wenn die Datei local_settings.py (im Verzeichnis /horizon/openstack_dashboard/local/) nicht richtig konfiguriert ist. In dieser Datei befindet sich ein Wörterbuch mit dem Namen IDM_USER_CREDENTIALS, in dem Sie das Kennwort für das Administratorprofil festlegen müssen, das beim Füllen der Keystone-Datenbank erstellt wurde. Es ist auch in der link angegeben, die Sie bereitgestellt haben. Versuchen Sie, das Passwort zu ändern und zu überprüfen, ob es funktioniert.
