1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/hoge.example.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/hoge.example.com/privkey.pem
Your cert will expire on 2020-03-18. To obtain a new or tweaked
version of this certificate in the future, simply run certbot again
with the "certonly" option. To non-interactively renew *all* of
your certificates, run "certbot renew"
- Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.

以下cron設定が追加される。
1日2回更新を試みる。30日前になると実際に更新される。
その際、Nginxのrestartは不要。
/etc/cron.d/certbot
# /etc/cron.d/certbot: crontab entries for the certbot package
#
# Upstream recommends attempting renewal twice a day
#
# Eventually, this will be an opportunity to validate certificates
# haven't been revoked, etc. Renewal will only occur if expiration
# is within 30 days.
#
# Important Note! This cronjob will NOT be executed if you are
# running systemd as your init system. If you are running systemd,
# the cronjob.timer function takes precedence over this cronjob. For
# more details, see the systemd.timer manpage, or use systemctl show
# certbot.timer.
