Lightsailに移行後放置していたらいつの間にか証明書の期限が切れていた。
期限切れのメールはこちら
Hello,
Your certificate (or certificates) for the names listed below will expire in 18 days (on 22 Jul 22 23:00 +0000). Please make sure to renew your certificate before then, or visitors to your web site will encounter errors.
We recommend renewing certificates automatically when they have a third of their total lifetime left. For Let's Encrypt's current 90-day certificates, that means renewing 30 days before expiration. See https://letsencrypt.org/docs/integration-guide/ for details.

For any questions or support, please visit: https://community.letsencrypt.org/ Unfortunately, we can't provide support by email.
For details about when we send these emails, please visit: https://letsencrypt.org/docs/expiration-emails/ In particular, note that this reminder email is still sent if you've obtained a slightly different certificate by adding or removing names. If you've replaced this certificate with a newer one that covers more or fewer names than the list above, you may be able to ignore this message.
If you are receiving this email in error, unsubscribe at:
You've been unsubscribed
Please note that this would also unsubscribe you from other Let's Encrypt service notices, including expiration reminders for any other certificates.
Regards,
The Let's Encrypt Team
どうやら証明書は3ヶ月間のみ有効だったらしい。
証明書の更新方法
更新方法は2つあり、ELBを利用して証明書を適用する方法と、無料の証明書(Let’s Encrypt)を利用する方法。
ELBはそれなりに料金がかかるので、今回はLet’s Encryptを採用。
調べたところ、LightsailのWordPressをHTTPS化する方法はいくつかあり、
・Certbotコマンドを利用
・Bitnami HTTPS 設定ツール(bncert)を利用
の2種類があるBitnamiは自動更新も可能なのでこちらでやっていきます。
