Ce que tu peux faire pour éviter de le télécharger chaque fois (car 90 jours après on sait plus où on a mis le fichier) ou être dans le bon répertoire pour le lancer.

cd /tmp
wget https://dl.eff.org/certbot-auto
cp certbot-auto /usr/sbin/
chmod 770 /usr/sbin/certbot-auto

et le jour que tu dois le renouveler

service nginx stop
certbot-auto renew
service nginx start

Automating renewal
The Certbot packages on your system come with a cron job that will renew your certificates automatically before they expire. Since Let's Encrypt certificates last for 90 days, it's highly advisable to take advantage of this feature. You can test automatic renewal for your certificates by running this command:

certbot renew --dry-run

Sinon => https://certbot.eff.org/docs/using.html#renewal

jgalode
Merci pour le partage. Je testerai prochainement.

Le mieux étant de mettre Cerbot dans /opt pas /tmp (le tuto indique /tmp, je vois pas trop pourquoi) sinon à chaque reboot ...

fabb24 Oui le renew tout simplement. Il te dira qu'il ne le fait pas vu qu'il reste X jours.

Bonsoir à tous,

Je me permets de faire appel à vous car, tout comme remonté par fabb24, je ne parviens pas à la relancer le service nginx après avoir modifié la conf.
