Apache2 startet täglich neu um 6:25 Uhr
02.03.2019 - Lesezeit: ~1 Minute

Apache2 startet täglich neu um 6:25 Uhr, was auf einem Rechner, der 24/7 läuft wenig Sinn macht. (Denn es gibt Leute, die zu dieser Zeit schon arbeiten.;-)

Deshalb habe ich den täglichen cron-job auf 2:25 Uhr umgestellt.

$ sudo nano /etc/crontab
# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 2    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 2    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 2    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
#
$ sudo service cron reload

Hintergrund

  • damit die Logdateien von Apache nicht zu groß werden werden diese mit Logrotate umbenannt und gepackt.
  • Logrotate stoppt deshalb den Apache bearbeitet die Logdateien und startet den Apache wieder 
    /etc/logrotate.conf
/etc/logrotate.d/apache2
  • Logrotate selbst wird vom cron.dayly aufgerufen 
    /etc/cron.daily/logrotate

Letsencrypt auf BBB erneuern
20.02.2019 - Lesezeit: 3 Minuten

Von Letsencrypt kommen E-Mails mit der Nachricht

You may need to update your client to the latest version in case it is still using the deprecated TLS-SNI-01 validation method. https://community.letsencrypt.org/t/february-13-2019-end-of-life-for-all-tls-sni-01-validation-support/74209

  • Neue Version von certbot 0.28 installieren

  • Mit dem neuen certbot das Zertifikat erneuern:

    $ certbot --version || /path/to/certbot-auto --version
certbot 0.28.0
$ sudo sh -c "sed -i.bak -e 's/^\(pref_challs.*\)tls-sni-01\(.*\)/\1http-01\2/g' /etc/letsencrypt/renewal/*; rm -f /etc/letsencrypt/renewal/*.bak"
$ sudo certbot renew --dry-run

  • Jetzt kommt die Fehlermeldung:

    IMPORTANT NOTES:
- The following errors were reported by the server:

  • Da certbot den http Zugriff auf bone.nfix.de benötigt, muss in der Fritzbox das Port 80 freigegeben sein.
