What is the proper procedure to renew a certificate
The ultimate goal is to auto renew using cron. But for now a cli renewal is adequate.
Two certificates located here:
(a) For reverse proxy within virtual host container for application on LAN behind firewall
(b) interactive DNS challenge using TXT RR
(a) Main server for other virtural host not behind firewall
After looking over the documentation the proper command to renew certificates is not clear from the following iterations:
<> certbot renew
<> certbot-auto renew
(a) Location (2) contain files
diff considers the files not different.
(b) Location (1) does not contain and iteration of renew.
Both certificates were obtained differently (1) DNS challenge TXT RR and (2) certbot. How are the certificates renewed and what are the proper commands / procedures to renew the certificates?
