javascript - Let's encrypt auto renewal (Nginx) 错误

Question

我正在尝试设置 greenlock-express在 nginx 代理后面运行。

这是我的nginx配置

# redirect
server {
    listen 80;
    listen [::]:80;
    server_name mydomain.com;

    location / {
        return 301 https://$server_name$request_uri;
    }
}

    }
}
...

我有 Node 服务器在端口 3000 (http) 和端口 3001 (https) 上运行。其他一切似乎都正常，但证书不会更新并在 3 个月后过期。

如果我关闭 nginx 并在端口 80 (http) 和端口 443 (https) 上运行 Node 服务器，那么它会更新证书。

我确保 .well-known/acme-challenge 被转发到 Node 服务器，即当我转到 url http(s)://mydomain.com/.well -known/acme-challenge/randomstr 我得到以下响应:

{ 
  "error": { 
    "message": "Error: These aren't the tokens you're looking for. Move along." 
  } 
}

为 ACME 身份验证分离 webroot 的简单方法。

为 ACME 身份验证创建一个 webroot 目录。

C:\www\letsencrypt\.well-known

在nginx配置中，将ACME认证的webroot设置为之前创建的目录。

http://example.com/.well-known/acme-challenge/token -> C:/www/letsencrypt/.well-known/acme-challenge/token

server {
    listen 80;
    listen [::]:80;
    server_name mydomain.com;

    location ^~ /.well-known/acme-challenge/ {
        default_type "text/plain";
        root C:/www/letsencrypt;
    }

    location / {
        return 301 https://$server_name$request_uri;
    }
}

重启 nginx。

您可以在 certbot 中更改您的 webroot 以重新获得身份验证。

certbot certonly --webroot -w C:\www\letsencrypt\ -d exapmle.com --dry-run

First, test it by adding the --dry-run option. Otherwise, you may experience issues limiting the number of authentication attempts.
