Nachfolgend werden die Schritte beschrieben, die nötig sind, um Nextcloud unter Ubuntu 26.04 LTS zu installieren.

• Installation
• Software-Konfiguration
• Generierung der TLS-Zertifikate für Nextcloud
• Den Webserver für Nextcloud vorbereiten
• Installation Nextcloud

Übersicht über Shortcuts des Editors “nano”: https://www.nano-editor.org/dist/latest/cheatsheet.html

Sicherung der Standard-Konfiguration:

cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak

Allgemeine Einstellungen nginx:

nano /etc/nginx/nginx.conf

Folgende Einstellungen sollten hier gesetzt bzw. kontrolliert werden:

• user www-data;
• worker_processes auto;
• server_tokens off;

Komplette nginx.conf:

user  www-data;
worker_processes  auto;
error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;
 
events {
    worker_connections  1024;
}
http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
    access_log  /var/log/nginx/access.log  main;
    sendfile        on;
    #tcp_nopush     on;
    keepalive_timeout  65;
    server_tokens off;
    #gzip  on;
    include /etc/nginx/conf.d/*.conf;
}

Deaktivierung der “Dummy-Webseite”:

mv /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf_disabled

“Selbsttest” der Konfiguration:

nginx -t

nginx neu starten:

service nginx restart

mysql_secure_installation für MariaDB nachinstallieren, weil in der aktuellen Version nicht mehr enthalten:

apt install mariadb-client-compat

Absicherung des Datenbanksystems:

mysql_secure_installation

Kopieren der Original-Einstellungen:

cp /etc/mysql/mariadb.conf.d/50-server.cnf /etc/mysql/mariadb.conf.d/50-server.cnf.bak

Öffnen der allgemeinen Konfiguration von MariaDB:

nano /etc/mysql/mariadb.conf.d/50-server.cnf

Fügen Sie folgende Zeilen direkt nach der Definition der Sektion [mysqld] ein:

innodb_read_only_compressed=OFF

# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
# Most important is to give InnoDB 80 % of the system RAM for buffer use:

#innodb_buffer_pool_size = 8G
# this is only for embedded server

# This group is only read by MariaDB servers, not by MySQL.
# If you use the same .cnf file for MySQL and MariaDB,
# you can put MariaDB-only options here
[mariadb]
# This group is only read by MariaDB-10.6 servers.
# If you use the same .cnf file for MariaDB of different versions,
# use this group for options that older servers don't understand
[mariadb-11.8]

Neustarten des Datenbank-Dienstes:

Sichern der config.php von Nextcloud. Den Benutzernamen ‘jan’ müssen Sie natürlich durch Ihren eigenen Benutzernamen unter Linux ersetzen. Diese Datei enthält sensible Informationen, daher die Datei an einem Ort speichern, auf den nur Sie Zugriff haben.

cp /var/www/nextcloud/config/config.php /home/eugen/config.php

Öffnen der Konfigurationsdatei von Nextcloud:

nano /var/www/nextcloud/config/config.php

Angabe der Startzeit des Wartungszeitfensters am Ende der Datei, aber noch vor der schließenden Klammer:

'maintenance_window_start' => 1,

Hinweis: Angabe erfolgt hier in UTC. Ein Wert von ‘1’ bedeutet hier also 01:00 UTC und dementsprechend 02:00 MEZ/03:00 MESZ.

config.php öffnen:

nano /var/www/nextcloud/config/config.php

Folgende Zeilen am Ende der Datei (aber vor der letzten schließenden Klammer) einfügen:

'filelocking.enabled' => true,
'memcache.locking' => '\OC\Memcache\Redis',
'redis' => array (
    'host' => '/var/run/redis/redis-server.sock',
    'port' => 0,
    'timeout' => 0.0,
),

Die Änderungen werden mit dem Speichern der config.php aktiv.

config.php öffnen:

nano /var/www/nextcloud/config/config.php

Am Ende (aber wieder vor der letzten schließenden Klammer) folgende Zeile einfügen:

'memcache.local' => '\OC\Memcache\APCu',
'memcache.distributed' => '\OC\Memcache\Redis',

Öffnen der Konfigurationsdatei von Nextcloud:

nano /var/www/nextcloud/config/config.php

Angabe der Standard-Telefonregion am Ende der Datei, aber noch vor der schließenden Klammer:

'default_phone_region' => 'AT',

Tragen Sie zunächst in den persönlichen Einstellungen Ihre private Mail-Adresse unter “E-Mail-Adresse” ein. Anschließend legen Sie ein neues E-Mail-Postfach an, welches nur für den Versand von Mail über die Nextcloud dient. Dazu können Sie auch einen beliebigen Freemail-Service nutzen. In den Admin-Einstellungen unter “Grundeinstellungen” muss anschließend der SMTP-Zugang konfiguriert werden. Hier eine Auswahl an SMTP-Einstellungen einiger Freemail-Anbieter:

• Google Mail:  https://support.google.com/mail/answer/7126229?hl=de#zippy=%2Cschritt-smtp--und-andere-einstellungen-im-e-mail-client-%C3%A4ndern
• GMX:  https://hilfe.gmx.net/pop-imap/pop3/serverdaten.html
• web.de:  https://hilfe.web.de/pop-imap/imap/imap-serverdaten.html

Crontab des Users www-data bearbeiten:

crontab -u www-data -e

Fügen Sie folgende Zeile ein:

*/5 * * * * php -f /var/www/nextcloud/cron.php > /dev/null 2>&1

In den Admin-Einstellungen unter ‘Grundeinstellungen’ sollte in der Nextcloud nun automatisch der Eintrag ‘Cron (Empfohlen)’

Die Configuration von Nextcloud verschieben

mv /etc/nginx/conf.d/nextcloudfuerdummies.decatec.de.conf /etc/nginx/sites-available/nextcloud.conf

Oder wenn die nicht existiert, dann

mv /etc/nginx/conf.d/nextcloud.conf /etc/nginx/sites-available/nextcloud.conf

Symlink setzen

ln -s /etc/nginx/sites-available/nextcloud.conf /etc/nginx/sites-enabled/nextcloud.conf

Nginx testen und neu laden

nginx -t
systemctl reload nginx

Datei öffnen

nano /etc/nginx/nginx.conf

Und füge innerhalb des http { … }‑Blocks, direkt unter der Zeile:

include /etc/nginx/conf.d/*.conf;

diese Zeile ein:

include /etc/nginx/sites-enabled/*.conf;

Der Block muss danach so aussehen:

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';
access_log  /var/log/nginx/access.log  main;
sendfile        on;
    keepalive_timeout  65;
    server_tokens off;
include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*.conf;
}

Speichern: CTRL+O Enter Beenden: CTRL+X Nginx testen

nginx -t

Muss „successful“ melden. Nginx neu laden

systemctl reload nginx

Port 443 testen

openssl s_client -connect wiki.hoeglinger.name:443 -servername wiki.hoeglinger.name | grep subject=
