ubuntu - Nginx 在配置中找不到时重定向到第一个按字母顺序排列的站点

Question

我有几个网站，当我输入一个不存在的子域时，Nginx 会重定向到/etc/nginx/sites-enabled 中的第一个可用网站。我的网站配置如下:

server { 
  listen 80; 
  listen [::]:80; 
  server_name *.example.com; 
  return 301 https://$host$request_uri; 
} 

server { 
   listen 443 ssl; 
   server_name *.example.com; 
   
   ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; 
   ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; 
   include /etc/letsencrypt/options-ssl-nginx.conf; 
   ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; 
   
   root /var/www/app_name/build;
   
   index index.html index.htm;
   
   location / {
      try_files $uri /index.html =404;
   }
}

完美，Ivan Shatsky 关于 default_server 的评论修复了它。但是我有一个错误 duplicate default_server error ，我用以下方法修复:

cd /etc/nginx/sites-enabled
unlink default
