Let's Encryptでワイルドカード証明書を取得する方法

Last updated at Posted at 2018-03-14

数時間前にアナウンスされたコミュニティの投稿で、ワイルドカードが緑色で有効になったとのニュースが!やったね

下の環境でできました

  • CentOS 7.4(新規で入れる方法はここ)
  • certbot 0.22.0(yum updateで降ってきた)

上記環境でなくてもpipとかgit cloneすればいけそう

sudo certbot certonly --manual -d *.example.com \
--preferred-challenges dns-01 \
--server https://acme-v02.api.letsencrypt.org/directory \
-m yourname@example.com

Ubuntuについて

PPA入れた状態でaptを更新しても0.21系なので調べたら以下の記事を見つけた

この投稿によると、しばらく(数週間)かかりそうやわすまんやでって書いてある。
