无法使用certbot续订SSL证书

Question

我正在尝试在AWS EC2服务器中续订我的SSL证书，但是我会遇到以下错误，因此经过大量的研究，我找不到解决方案。

我运行的命令：

$ sudo certbot renew --dry-run

错误：

Answer 1

在我的情况下，我将默认用作/etc/nginx/sites-sites-enabled文件夹的文件名。将其更改为yoursite.com，您是您的网站地址。 sudo certbot续订 - 直接运行开始工作正常。
也许对某人有帮助：

# Rename file
cd /etc/nginx/sites-enabled
mv ./default ./yoursite.com
# Update certs, don't forget to replace yoursite.com with your address
sudo certbot --nginx -d yoursite.com -d www.yoursite.com
# Check nginx config
nginx -t
# Restart nginx to apply certs
sudo systemctl reload nginx
# Check renew
sudo certbot renew --dry-run

Answer 2

如果您刚刚添加了证书，并且正在测试续订过程，则需要重新启动Web服务器以在尝试续订之前激活/应用新证书。

Answer 3

根据给出的错误，您需要确保您试图创建证书的域名指向服务器。

您可能需要a DNS条目mydmain.com指向您的服务器IP。

我相信这就是Letsencrypt确保域名的所有权。
