取得 certbot-auto 及執行
|
1 2 |
# wget https://dl.eff.org/certbot-auto # chmod a+x ./certbot-auto |
單一網站
|
1 |
# certbot certonly --webroot -w /WEBSite/www/WWW/ -d hoyo.idv.tw |
通配網址
|
1 |
# ./certbot-auto certonly --manual --preferred-challenges dns -d *.hoyo.idv.tw |
執行，記得產生一個通配網域一個只有網域名稱證書，如此單獨使用網域名稱時才不會 SSL_ERROR_BAD_CERT_DOMAIN 證書問題

通配網域使用 DNS 認證
|
1 |
# ./certbot-auto certonly --manual --preferred-challenges dns -d *.hoyo.idv.tw -d hoyo.idv.tw |
--
網頁認證
不過認證之前必須注意要把網址 Rewrite 關閉，例如 http 轉 https，否則會失敗
--
Online dig
--
--
自動更新證書
- BIND9 DNS Challenge自动配置Letsencrypt通配符(Wildcard)HTTPS证书
- Let's Encrypt 证书生成，certbot-auto 生成 ssl 通用证书 配置 https 自动续期
- certbot
-目前手動更新中-
--
其他注意事項
- 失敗的指令也會算在 Rate Limits
- SSL_ERROR_BAD_CERT_DOMAIN : hoyo.idv.tw 不等於 *.hoyo.idv.tw ，必須使用 hoyo.idv.tw 證書或是將 hoyo.idv.tw 轉到 www.hoyo.idv.tw 才能套用通配網域證書
