Let's Encrypt 的 NXDOMAIN 机制到底是怎样的

loveminds

程序是这个 https://oneinstack.com/faq/letsencrypt/ 基于 ACME
直接添加单一的不带 www 的域名是没有问题的，一加 www 马上根就 NX，加泛域名根也 NX

What Are You Doing?
1. Use HTTP Only
2. Use your own SSL Certificate and Key
3. Use Let's Encrypt to Create SSL Certificate and Key
q. Exit
Please input the correct option: 3

Please input domain(example: www.example.com): aaa.com
domain=aaa.com

Please input the directory for the domain:aaa.com :
(Default directory: /data/wwwroot/aaa.com):
Virtual Host Directory=/data/wwwroot/aaa.com

Create Virtul Host directory......
set permissions of Virtual Host directory......

Do you want to add more domain name? [y/n]: y

Type domainname or IP(example: example.com other.example.com): www.aaa.com
domain list=www.aaa.com

Let's Encrypt Verify error! DNS problem: NXDOMAIN looking up A for aaa.com


# dig aaa.com

; > DiG 9.9.4-RedHat-9.9.4-51.el7_4.2 > aaa.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER> DiG 9.9.4-RedHat-9.9.4-51.el7_4.2 > www.aaa.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER

写的好复杂。API key添加即可。
就是通过acme.sh添加出现频繁的NXDOMAIN，DNS本身没有问题

Jetso

直接用  acme.sh  ，不要瞎折腾

太高深不懂 ，我是VPS装了acme.sh，全自动的。

一直非常奇怪的一件事，不加www这个第二域名的情况下，并不会NX

我的也是，确定不是dns问题。第一个直接abc.com,第二个*.abc.com，但是签出来的是abc.com的证书，并不是*.abc.com的
