即使设置了权限，Nginx 403 也被禁止

Question

我想为我的域获取 Letsencrpyt SSL。该过程的一部分是，该站点需要在获得证书之前获得授权。

我创建了文件夹./well-known 并运行了我被要求执行的命令，我得到了；

Nginx 403 forbidden.

我在 nginx/1.10.0 (Ubuntu)

我chown 该目录并授予它755 但仍然相同。查看下面我的目录中的权限。

namei -l /var/www/example.com/.well-known                      

 f: /var/www/example.com/.well-known
 drwxr-xr-x root   root /
 drwxr-xr-x root   root var
 drwxr-xr-x root   root www
 drwxr-xr-x cman sudo example.com
 drwxr-xr-x cman sudo .well-known

我还在/.well-known 文件夹中创建了一个working.html 文件并加载了example.com/.well-known/working.html，我得到了相同的403 Forbidden。

Nginx.conf

 upstream kip_app_server {
   # fail_timeout=0 means we always retry an upstream even if it failed
   # to return a good HTTP response (in case the Gunicorn master nukes a
   # single worker for timing out).

    server unix:/var/www/example.com/src/run/trav.sock fail_timeout=0;
}

server {
      listen 80;
      server_name example.com www.example.com;

  }

   location ~ /\.well-known {
       allow all;
       alias /var/www/example.com/.well-known/;
    }


    location / {
      include proxy_params;
       proxy_pass http://kip_app_server;
       #proxy_set_header X-Forwarded-Host $server_name;
      #proxy_set_header X-Real-IP $remote_addr;
   }
 }

如果您不使用别名，您的代码将可以工作。

试试这个：

location ^~ /.well-known {
   allow all;
   alias /var/www/example.com/.well-known/;
}

或者这个：

location ^~ /.well-known {
    allow all;
    auth_basic off;
    alias /path/to/.well-known/;
}

别名时，^ 是必需的。

这是 Nginx 特定的行为，它们执行匹配的方式。这里有关于匹配逻辑和警告的详细文章，令人困惑：https://github.com/letsencrypt/acme-spec/issues/221
