Situação
Eu escrevi uma unidade de serviço systemd personalizada e seu script de shell complementar para renovar um certificado de Vamos criptografar . Tudo funciona bem quando eu corro systemctl start letsencrypt-example_com.service
. Eu quero que ele seja executado automaticamente a cada 60 dias, então eu escrevi uma unidade temporizada systemd.
Problema
Eu corri systemctl enable letsencrypt-example_com.timer
then systemctl start letsencrypt-example_com.timer
. O temporizador parece começar, mas não o serviço.
# 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
