Requirements

  • PostgreSQL
  • PHP (mit php-ldap, php-pgsql, php-redis)
  • nginx
  • redis

Unsere NextCloud Einstellungen

  • autoconfig.php – Datenbank + Adminaccount
    • PostgreSQL
    • Admin zur Basisconfiguration
  • LDAP – mit UCS-LDAP und nextCloud-LDAP-Plugin
    • > seperater LDAP-Benutzername für LDAP
    • > BaseDN cn=users,dc=dezentrale,dc=intranet
    • > Benutzernamen als uid damit Benutzer = nick (Experteneinstellungen)
    • > Gruppen-Member als memberUid um Administration über LDAP zu ermöglichen (Advanced -> Directory)
  • Gruppenordner
    • > Gruppen und deren Mitglieder werden aus LDAP entnommen und entsprechend verknotet


NextCloud Tools

- OCC (OwnCloudClient) – Terminalclient für die Administration

Migration von UCS

  • Nextcloud installieren (herunterladen von Website https://download.nextcloud.com/server/releases/)
    • Datenbank im PostgresSQL erstellen und Nutzer inkl. Rechten definieren
      • CREATE USER nextcloud WITH PASSWORD 'password'; CREATE DATABASE nextclouddb TEMPLATE template0 ENCODING 'UNICODE';
      • ALTER DATABASE nextclouddb OWNER TO username; GRANT ALL PRIVILEGES ON DATABASE nextclouddb TO nextcloud;
    • tarball entzippen (/var/www/nextcloud)
    • nginx config erstellen 
      • upstream php-handler {
    #server 127.0.0.1:9000;
