来自 .well-known/acme-challenge/<token> 的无效响应：404 + nginx

  • 772

我看过这些问题（^，^，^，^），但不幸的是它们都不能解决我的问题。

我正在尝试使用 certbot 为我的子域之一获取 SSL 证书。但是，在测试 .well-known/acme-challenges/ 时，挑战失败。Web服务器（nginx）返回404。准确的错误是：

Waiting for verification...                                                                      
Challenge failed for domain api.example.com                                                        
http-01 challenge for api.example.com             
                        
Certbot failed to authenticate some domains (authenticator: manual). The Certificate Authority reported these problems:                          
  Domain: api.example.com                         
  Type:   unauthorized  
  Detail: 139.x.x.x: Invalid response from http://api.example.com/.well-known/acme-challenge/7AujpY6MnpBkHAmVihpVSQXcEMYuMZFHjywSsAICtvQ: 404                                                 

Hint: The Certificate Authority failed to verify the manually created challenge files. Ensure that you created these in the correct location.

我什至从单独的系统手动运行以下命令来获取证书：

certbot -v certonly --manual --dry-run -d api.example.com

但是，我又遇到了同样的错误。我根据相应文件夹（/var/www/certbot/）中的说明创建了该文件并复制了其内容。我什至给了文件和certbot文件夹777权限并重新启动了Web服务器，但仍然不起作用。

Create a file containing just this data:                                                         

7AujpY6MnpBkHAmVihpVSQXcEMYuMZFHjywSsAICtvQ.HQdAzFVYjmgUdQRvdJTBMm2eC2ZLOw-G-4TZr6JB0ak                                                          
And make it available on your web server at this URL:

似乎根本无法访问/.well-known/acme-challenge/。即使我在 中创建了一个普通的 HTML 文件/.well-known/acme-challenge/，仍然无法访问它。

我为域本身 ( http://example.com/.well-known/acme-challenge/) 执行此操作，该域的证书已收到，但我仍然无法访问/.well-known/acme-challenge/.

    Certbot 使用 URLhttp://example.com/.well-known/acme-challenge/...查找其质询/响应文件。

    Nginx 使用该root指令root通过将值与URL 的“路径”部分连接起来将 URL 转换为文件名。

    给定location块：

    location /.well-known/acme-challenge/ {
    allow all;
    root /var/www/certbot;
}

    URLhttp://example.com/.well-known/acme-challenge/foo期望foo在目录中找到该文件：

    /var/www/certbot/.well-known/acme-challenge

    您可以certbot使用-w命令行选项进行调用，为质询/响应文件指定相同的路径。例如：

    certbot certonly --webroot -w /var/www/certbot -d api.example.com
