![在 Debian8.7-Jessie Linux 上安装 Certbot 时获取验证数据时出错](https://linux22.com/image/710116/%E5%9C%A8%20Debian8.7-Jessie%20Linux%20%E4%B8%8A%E5%AE%89%E8%A3%85%20Certbot%20%E6%97%B6%E8%8E%B7%E5%8F%96%E9%AA%8C%E8%AF%81%E6%95%B0%E6%8D%AE%E6%97%B6%E5%87%BA%E9%94%99.png)
我刚刚设置了我的服务器,但我无法使我的配置与 Certbot 配合使用。总是这样。我尝试了一些不同的配置,但都不起作用。这是我的最后一次尝试。它总是说:“获取验证数据时出错”有人知道为什么这不起作用吗?

答案1
您的 apache 服务器是否可在 vhost 的域中外部(更大的互联网)使用?当您请求证书时,certbot 会修改您的 apache 配置以将验证令牌发送到您网站上的特殊 URL(通常是)/.well-known/acme-challenge/<sometoken>
。然后,Let's Encrypt 将尝试使用您正在为其请求证书的域名来访问该路径。这就是他们确认您公开拥有您正在为其请求证书的域的方式。
如果该网络服务器不是公共的,或者没有与指向它的虚拟主机匹配的公共 DNS 条目,Let's Encrypt 将无法请求其授权令牌。

我需要使用以下行来配置 iptables:
sudo iptables -I INPUT 1 -p tcp --dport 443 -j ACCEPT
答案3
将我的网站从一台服务器迁移到另一台服务器后也遇到了类似的问题。问题是 HTTP 被重定向到 HTTPS,而 HTTPS 尚未正确配置。删除重定向后,可以certbot

为了记录,我得到了
