Let’s Encrypt Zertifikat erstellen:

sudo certbot certonly --webroot -w /var/www/html/ -d DOMAIN.de -m EMAIL --agree-tos

Let’s Encrypt Zertifikat automatisch aktualisieren:

sudo nano /etc/crontab ODER crontab -e

Dort vor der abschließenden Raute folgenden Befehl einfügen:

PATH=/usr/sbin:/usr/bin:/sbin:/bin
0 0 5 * * /usr/bin/certbot renew --post-hook "service nginx restart"

1. Stelle: Minute -> 0 (0 Minuten)
2. Stelle: Stunde -> 0 (0 Uhr)
3. Stelle: Tag des Monats -> 5 (am 5. des Monats)
4. Stelle: Monat -> * (jeden Monat)
5. Stelle: Wochentag -> * (jedes Jahr)

sudo service cron reload

Konfiguration letsencrypt renewal ändern

sudo nano /etc/letsencrypt/renewal/it-for-me.spdns.de.conf

statt

post_hook= /usr/sbin/nginx restart

besser

pre_hook = sudo systemctl restart nginx.service

#### (erst mal nicht nötig) Nginx Konfiguration anpassen: ####

sudo nano /etc/nginx/sites-enabled/default

return 301 https://$server_name$request_uri;
#root /var/www/html/

#Mit Strg + O, Enter & Strg +X die Datei speichern#

sudo systemctl restart nginx.service
