LetsEcrypt SSL証明書の更新(2022/04/01実施)

Saturday, April 2nd, 2022

LetsEncrypt SSL証明書を更新した。

前回、前々回の更新と同様、ディレクトリ /etc/letsencryptを削除後、新たにletsencryptを作成する手順で更新。

新規作成後、httpd を再起動。その後、証明書の有効期限を確認。

以下、更新時ログ:

Please deploy a DNS TXT record under the name:

_acme-challenge.yamasnet.com.

with the following value:

*******************************************

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 2022-06-30.
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.
