+Im letzten Teil dieser Reihe haben wir eine grundlegende CAPEv2-Umgebung aufgebaut. 
+Außerhalb dieser Blogpost-Reihe habe ich auch noch ein paar andere VMs installiert mit anderen Betriebssystemen.
 
+## Guacamole installieren
 
+```sh
+cd /opt/CAPEv2/installer/
+./cape2.sh guacamole | tee guacamole.log
+systemctl status guacd guac-web
+```
+
+## CAPE-Web-Service
+
+in der `/opt/CAPEv2/conf/web.conf` das Guacamole-Feature aktivieren:
+```ini
+[guacamole]
+enabled = yes
+mode = vnc
+username =
+password =
+guacd_host = localhost
+guacd_port = 4822
+# Server that exposes the VNC ports (e.g., your KVM host)
+vnc_host = localhost
+# You might need to add your server IP to ALLOWED_HOSTS in web/web/settings.py if it not ["*""]
+# vnc or rdp
+guest_protocol = vnc
+guacd_recording_path = /opt/CAPEv2/storage/guacrecordings
+guest_width = 1280
+guest_height = 1024
+# rdp settings
+guest_rdp_port = 3389
+```
+
+In dieser Datei kann man auch z.B. Authentifizierung aktivieren, persönlich würde ich das jedoch eher an einem
+vorgelagerten Reverse-Proxy bzw. WAF tun.  
+
+Nach der Änderung dieser Konfiguration sollte man die `cape-web` und `guacd`-Dienste neu starten.  
+
+## Webserver/Reverse-Proxy
+
+Die genauere Konfiguration für Nginx im Produktivbetrieb ist etwas aufwändiger, siehe dazu
+[CAPEv2 Docs Nginx](https://capev2.readthedocs.io/en/latest/usage/web.html#best-practices-for-production)
