はじめに
ConoHaVPSでKUSANAGI動かしてWordPress動かしてますが、なぜかhttpsで無効な証明書と出てきてしまいました。
とりあえず回復までの道のりを書いていきます。
一体何が起こっていたのか？
とにかく自分のWPサイトが証明書のエラーになるので、 /home/kusanagi/（省略）/DocumentRoot/ を調べたところ .well-known フォルダが無い事に気づきました。
…ということは、更新が出来てないということで、とりあえず yum -y update をかけましたが、アップデートは無いようで、仕方が無いので kusanagi update cert をすると、エラーの嵐。
いったいどうすれば？と悩みました。
まずnginxをチェック
# nginx -t -c /etc/nginx/nginx.conf
と入れてみたところ、エラー吐いていたので、とりあえずエラーの元を修正しました。
Let's Encryptの証明書を強制的に更新してみた。
KUSANAGIの場合、 certot-auto にパスが通ってないので、調べてみたら、 /usr/local/certbot/certbot-auto にありました。
下記のコマンドで強制的に証明書を更新させました。
# /usr/local/certbot/certbot-auto --force-renew
# /usr/local/certbot/certbot-auto --force-renew
