LetsEncrypt SSL証明書の更新(2022/06/14実施)

Tuesday, June 14th, 2022

単なる更新履歴。

LetsEncriptにはお世話になっているが、SSL証明書の更新期限が3か月であることが大変。

前回更新したのが4月1日だったので6月までには更新する必要ある。

スクリプトを書いて自動更新できればいいと思うが、wild card の照明書を用いているので、更新ごとにDNSレコードの書き換えをマニュアルで行なっている。

結果、システム維持には、煩雑な更新作業が3か月ごとに必要。

更新の手順は前回と全く同じ。

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:

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.

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.
