使用 certbot 更新证书以添加子域

Question

我有一个域，其中安装了 LetsEncrypt 证书和 apache conf 设置，可以将 www 转发到非 www，将非 ssl 转发到 ssl。一切都很好，直到我决定添加一个子域并尝试生成一个新证书来涵盖这两个域。

现在我在运行 certbot 时得到以下输出：

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?

 - 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.

此外，我已将我的 000-default.conf 文件的内容复制到下面：

Answer 1

您似乎有几个 .conf 个文件可能会导致冲突。

方法一：将所有<VirtualHost *:80>和<VirtualHost *:443> 同一配置文件中的规则
方法二：分开放置在末尾添加 Include /path/to/httpd-le-ssl.conf 000-default.conf

运行$ sudo certbot renew --dry-run查看修改配置成功还是失败

使用 --dry-run 不会影响您排除故障和修复配置时的限制。成功完成后，您可以通过各种方式运行 certbot 并期望一切正常。

Answer 2

我在尝试一次为多个域安装证书时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，请尝试分别为域安装证书。

示例：

当您需要为以下域安装证书时

domain01.com
www.domain01.com
domain02.com
www.domain02.com

在步骤

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，然后重复安装 3、4

Answer 3

我遇到了同样的问题。下面的步骤已经解决了我的问题。

如果您已经尝试设置 SSL，请删除所有现有的 certbot 文件。按照此 link 如何从系统中删除现有的 Certbot 文件 https://askubuntu.com/a/1195603/871518
将所有单独的域与单个 vhost.conf 文件分开。示例：

          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“serverAlias”包含在您的虚拟列表中，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
```

Select第一趟只有1和3

是的，您已经成功地完成了 domain1.com SSL 支持，并再次按照相同的方式进行 SSL 支持 domain2.com :

sudo certbot --apache

Answer 4

当您运行此命令时，请确保您的顺序也正确。因此，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。
