Situation
J'ai écrit une unité de service personnalisée et son script shell compagnon pour renouveler un certificat de Crypter Let . Tout fonctionne bien quand je cours systemctl start letsencrypt-example_com.service
. Je veux qu'il s'exécute automatiquement tous les 60 jours, j'ai donc écrit une unité de minuterie systemd.
Problème
J'ai couru systemctl enable letsencrypt-example_com.timer
alors systemctl start letsencrypt-example_com.timer
. La minuterie semble démarrer mais pas le service.
# systemctl status letsencrypt-example_com.timer
Created symlink from /etc/systemd/system/timers.target.wants/letsencrypt-example_com.timer to /etc/systemd/system/letsencrypt-example_com.timer.
# systemctl start letsencrypt-example_com.timer
# systemctl list-timers --all
# systemctl list-timers
