===== Betrieb =====
==== Nextcloud aktualisieren (auf der Konsole) ====

  - Updater ausführen
    * **sudo -u www-data php /var/www/public_html/updater/updater.phar**
      * Start update? [y/N] **y**
      * Should the "occ upgrade" command be executed? [Y/n] **y**
      * Keep maintenance mode active? [y/N] **n**
  - In Nextcloud einloggen und unter [[https://cloud-test.technikkultur-erfurt.de/settings/admin/overview|Einstellungen - Verwaltung - Übersicht]] prüfen. Folgende Fehler sind "normal":
    * Dein Web-Server ist nicht richtig eingerichtet um "/.well-known/caldav" aufzulösen.
    * Dein Web-Server ist nicht richtig eingerichtet um "/.well-known/carddav" aufzulösen.
    * Es wurde kein PHP-Memory-Cache konfiguriert.
  - Angezeigte Fehler prüfen und korrigieren
    - Nutzung von OCC: **sudo -u www-data /var/www/public_html/occ ...**

==== Backup  ====

  Dateien per Shell sichern
    - cd /var/www/public_html
    - sudo -u www-data php occ maintenance:mode --on
    - sudo tar -cpzf //nc_backup_`date +"%Y%m%d"`.tar.gz -C /var/www/public_html/ .

===== Installation =====

  * Standard-Template mit Benutzern

==== NGINX / PHP ====

  - NGINX und PHP-FPM installieren
