Nginx 不存在的域名无法路由到404页面

我的 Nginx 配置文件包含几个服务器块，如下所示。使用以下配置，它会将不存在的域重定向到配置文件中的第一个服务器块。但是我想将不存在的域重定向到 404 页面。

 server 
{    
listen      443 ssl http2;
server_name     test-domain.no;
access_log  /var/log/nginx/nginx.access.log;
error_log   /var/log/nginx/nginx.error.log;
ssl    on;
ssl_certificate    /etc/nginx/ssl/certificates.pem;

ssl_session_timeout 1d;
ssl_session_cache builtin:1000 shared:SSL:10m;
ssl_session_tickets off;

location /

    proxy_pass         http://test-domain-sps.3fcf2715.cont.dockerapp.io:80/;
    proxy_redirect     off;

    ##proxy_set_header   Host             $host;
    proxy_set_header   X-Real-IP        $remote_addr;
    proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

    client_max_body_size       10m;
    client_body_buffer_size    128k;

    proxy_connect_timeout      90;
    proxy_send_timeout         90;

    proxy_busy_buffers_size    64k;
    proxy_temp_file_write_size 64k;
}
}

# Redirect from HTTP to HTTPS
server { 
 listen 80;
 server_name test-domain.no; 
 return 301 https://test-domain.no$request_uri;
 #rewrite ^/(.*) https://test-domain.no/$1 permanent; 
}

#others server blocks...

如果您能告诉我如何将配置文件中不存在的域路由到 404 页面，我将不胜感激。

答案1

您应该使用以下配置来返回 404 标头。

server {
  server_name _;
  listen 80 default_server;
  return 404;
}

如果你需要添加自定义 404 页面，则可以使用以下命令

server {
  server_name _;
  listen 80 default_server;
  error_page 404 http://example.com/404.html;
  return 404;
}

答案2

我在配置文件末尾为不存在的 HTTPS 域设置了以下几行，它工作正常。因为它可能对某些人有帮助，所以我把它发布在这里：

server {
 server_name _;
 listen 443 ssl;
 ssl_certificate    /etc/nginx/ssl/cert.pem;
 ssl_certificate_key    /etc/nginx/ssl/serve.key;
 return 404;
}
