早いもので，最初にLet’s Encryptを導入<\/a>した，私が管理するサイトの証明書の有効期限まであと19日だというメールが，Let’s Encryptのシステムから来ました．<\/p>\n

そこで，以前調べた，<\/p>\n

certbot renew<\/pre>\n
を実行しましたがエラーが出ます．ネット検索してもこれだっ! ていう解決策は見つからず，どうしようか迷っていました．<\/p>\n
まだ19日あるんですが，それまでずるずると解決策を探して試みるのも嫌なので，即決すべく，もう少し検索をしてみたところ，renewにこだわらず，新規に証明書を得た時の方法をもう一度実行すれば良いのだ，という情報を得ました．<\/p>\n
で，そのようにしてみました．新しい証明書は，ファイル名に2が付いて，古い証明書に上書きされることもありません．<\/p>\n
当サイトはそのサイトより少し遅れてLet’s Encryptを導入したのでまだ1か月くらいは余裕があるはずなのですが，ずらして更新するのもめんどくさいので，続けて，同じく新規に得る手続きで，更新しました．<\/p>\n","protected":false},"excerpt":{"rendered":"
