Oh, and don’t forget. Your certificates are valid for 3 months (90 days) unless you renew them. To automate this renewal process you can add the letsencrypt-auto renew command to your crontab.
If you check every 60 days you will never run out of valid certificates.
To run the script manualy (from the /opt/letsencrypt directory)
Add to crontab :
sudo crontab -e
and add this rule
30 2 * * 1 /opt/letsencrypt/letsencrypt-auto renew >> /var/log/le-renew.log
Logs for the renewal will be stored at /var/log/le-renew.log
