December 13, 2024 – 2:32 pm

LetsEccrypt SSl の有効期限が近付いたので更新した。

以下、更新時のLogを掲載:

[root@Server02 ~]# certbot certonly --manual
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Please enter the domain name(s) you would like on your certificate (comma and/or
space separated) (Enter 'c' to cancel): *.yamasnet.com

Please deploy a DNS TXT record under the name:

_acme-challenge.yamasnet.com.

with the following value:

k2rEXXymL_zXYT8v4yHy5rp7PsuaNHwMA-8hwGsTrs8

Before continuing, verify the TXT record has been deployed. Depending on the DNS
provider, this may take some time, from a few seconds to multiple minutes. You can
check if it has finished deploying with aid of online tools, such as the Google
Admin Toolbox: https://toolbox.googleapps.com/apps/dig/#TXT/_acme-challenge.yamasnet.com.
Look for one or more bolded line(s) below the line ';ANSWER'. It should show the
value(s) you've just added.

Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/yamasnet.com/fullchain.pem
Key is saved at:         /etc/letsencrypt/live/yamasnet.com/privkey.pem
This certificate expires on 2025-03-13.
These files will be updated when the certificate renews.

NEXT STEPS:
- This certificate will not be renewed automatically. Autorenewal of --manual certificates requires the use of an authentication hook script (--manual-auth-hook) but one was not provided. To renew this certificate, repeat this same certbot command before the certificate's expiry date.
