使用certbot更新证书以添加子域

时间:2019-04-21 00:01:42

标签: ssl apache2 certbot

我有一个安装了LetsEncrypt证书和apache conf设置的域,用于将www转发到非www并将non-ssl转发到ssl。一切正常,直到我决定添加一个子域并尝试生成一个新证书来覆盖这两个域。

现在,当我运行certbot时,将得到以下输出:

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?

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.

此外,我还复制了下面的000-default.conf文件的内容:

您似乎有几个.conf文件可能会引起冲突。

  • 方法1:放置所有VirtualHost *:80><VirtualHost *:443> 相同配置文件中的规则
  • 方法2:将它们分开并 将Include /path/to/httpd-le-ssl.conf添加到 000-default.conf

运行$ sudo certbot renew --dry-run来检查修改后的配置是成功还是失败。

在进行故障排除和修复配置时,使用--dry-run不会影响您的限制。成功完成后,您可以再次运行renew命令,而无需使用--dry-run

一次尝试为多个域安装证书时,出现相同的错误消息。如果所有VirtualHost都位于同一配置文件中,并且不想分开它们,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

  1. domain01.com
  2. www.domain01.com
  3. domain02.com
  4. 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

我遇到了同样的问题。下面的步骤已经解决了我的问题。

  1. 如果您已经尝试设置 SSL,请删除所有现有的 certbot 文件。 按照此链接如何从系统中删除现有的 Certbot 文件 https://askubuntu.com/a/1195603/871518

  2. 将所有单个域与单个 vhost.conf 文件分开。 示例:

<块引用>
          domain1.conf
          domain2.conf
Enable vhost in your created two new file by typing : 
<块引用>
   a2ensite domain1.conf
   a2esnite domain2.conf
  1. 运行 certbot 命令:
<块引用>
    sudo certbot --apache
  1. 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
    

在第一次旅程中只选择 1 和 3

  1. 是的,您已成功完成对 domain1.com SSL 的支持,并再次遵循相同的 SSL 支持操作domain2.com
<块引用>

sudo certbot --apache

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。
