Certbot - DNS 问题:NXDOMAIN 为 xxx 查找 A - 检查此 DNS 记录是否存在 [英] Certbot - DNS problem: NXDOMAIN looking up A for xxx - check that a DNS records exists for this

问题描述

所以我尝试运行以下

sudo certbot certonly --nginx --dry-run -d subdomain.domain.com -d www.subdomain.domain.com

这给了我一个 DNS 问题，但是，它在运行时有效

That gave me a DNS problem, however, it worked when running

sudo certbot certonly --nginx --dry-run -d subdomain.domain.com

我的 DNS 记录中是否遗漏了什么?

Am I missing something in my DNS records?

我已经成功运行

sudo certbot certonly --nginx --dry-run -d domain.com -d www.domain.com

如果我使用子域，是否需要为www"部分创建特定的 DNS 记录?

Do I need to make a specific DNS record for the ´´www´´ part if I use subdomains?

编辑运行dig subdomain.domain.com"的结果

Edit Result of running ´´dig subdomain.domain.com´´

回答

使用主机www.subdomain"创建一个 A 类条目，您就很好

Create an type A entry with the host ´´www.subdomain´´ and you're good

推荐答案

从问题中添加正确答案:

Adding proper answer from the question:

使用主机www.subdomain"创建一个 A 类条目，您就可以了

Create an type A entry with the host "www.subdomain" and you're good

根据我的经验，我想再等 5 分钟到一个小时，让记录生效，让 certbot 能够看到它.

I'd add to wait anywhere between 5 minutes to an hour for the record to take effect and for certbot to be able to see it, from my experience.
