我有一个安装了LetsEncrypt证书和apache conf设置的域，可以将www转发到非www，将非SSL转发到SSL。一切都运行良好，直到我决定添加一个子域并尝试生成一个新证书来涵盖两者。
现在，当我运行 certbot 时，我得到以下输出：
root@arthas:~# certbot

You have an existing certificate that contains a portion of the domains you
requested (ref: /etc/letsencrypt/renewal/domain.com.conf)
It contains these names: domain.com, www.domain.com
You requested these names for the new certificate: domain.com,
playground.domain.com, www.playground.domain.com, www.domain.com.
Do you want to expand and replace this existing certificate with the new
certificate?

An unexpected error occurred:
ValueError: Unable to set value to path!
Please see the logfiles in /var/log/letsencrypt for more details.
IMPORTANT NOTES:
- Unable to install the certificate
- Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/domain.com/fullchain.pem
Your key file has been saved at: /etc/letsencrypt/live/domain.com/privkey.pem
Your cert will expire on 2019-07-19.
To obtain a new or tweaked version of this certificate in the future, simply run certbot again with the "certonly" option.
To non-interactively renew *all* of your certificates, run "certbot renew"
- Some rewrite rules copied from /etc/apache2/sites-enabled/000-default.conf were disabled in the vhost for your HTTPS site located at /etc/apache2/sites-enabled/000-default-le-ssl.conf because they have the potential to create redirection loops.
另外，我在下面复制了我的 000-default.conf 文件的内容：
# Added to mitigate CVE-2017-8295 vulnerability

</VirtualHost>
尝试一次性为多个域安装证书时，我会收到相同的错误消息。如果您将所有 VirtualHost 都放在同一个配置文件中，并且不想将它们分开，请尝试单独为域安装证书。
例：
当您需要为以下域安装证书时
- domain01.com
- www.domain01.com
- domain02.com
- www.domain02.com
在台阶上
Select the appropriate numbers separated by commas and/or spaces, or leave input blank to select all options shown (Enter 'c' to cancel): 1,2,3,4
输入 1， 2 而不是 1,2,3,4，然后重复以安装 3， 4
运行此命令时，请确保顺序也正确。 例如：example.org 应该在请求中的 mail.example.org 之前。 否则，尤其是在使用 Route 53 选项时，会收到奇怪的区域错误消息。
看起来您有几个可能导致冲突的.conf文件。
- 方法1：放置所有
<VirtualHost *:80>并<VirtualHost *:443>同一配置文件中的规则 - 方法 2：将它们分开并将
Include /path/to/httpd-le-ssl.conf添加到000-默认.conf
运行$ sudo certbot renew --dry-run以检查修改后的配置是成功还是失败。
使用 --dry-run 不会影响故障排除和修复配置时的限制。成功完成后，您可以以各种方式运行certbot并期望一切正常。
我遇到了同样的问题。以下步骤已解决我的问题。
-
如果您已尝试设置 SSL，请删除所有现有的 certbot 文件。点击此链接如何从系统中删除现有的Certbot文件https://askubuntu.com/a/1195603/871518
-
将所有单个域与单个 vhost.conf 文件分开。例：
domain1.conf domain2.conf
Enable vhost in your created two new file by typing :
a2ensite domain1.conf a2esnite domain2.conf
- 运行 certbot 命令：
sudo certbot --apache
如果虚拟列表中包含"服务器别名"，您可能会看到 4 个域列表：
1. domain1.com 2. domain2.com 3. www.domain1.com 4. www.domain2.com
在第一个旅程中仅选择 1 和 3
- 是的，您已成功完成 domain1.com SSL 支持，并再次遵循相同的 SSL 支持 domain2.com：
