我從 Nginx 開始。

我安裝在我的伺服器上：

• 1 www.example.com 上的 Drupal 站點
• 1 Analytics.example.com 上的 GoAccess 站點
• 1 monitoring.example.com 上的網路數據站點

IP 地址和 example.com 必須重定向到 www.example.com

所有域和子域 dovent 重定向到 https

在我的 OVH 網路主機上，我創建了域 example.com www.example.com analytics.example.com monitoring.example.com 指向我的伺服器的 IP 地址。

當我在瀏覽器的地址欄中輸入伺服器的 IP 地址時，它會重定向到 analytics.example.com 為什麼？

如何重定向到 www.example.com ？

在為 analytics.example.com 和 monitoring.example.com 創建配置之前，它起作用了。

當我測試我的配置時：

您需要使用 default_server 指令。我認為您需要在一個 http 和一個 https 塊上使用它。

server {
 listen 443 ssl http2;
 listen [::]:443 ssl ipv6only=on http2;
 server_name www.domaine.com default_server;
 root /var/www/www-domaine-com/web;
 // etc
}

server {
 listen 80;
 server_name www.domaine.com default_server;
 root /var/www/www-domaine-com/web;
 // etc
}

在我的伺服器上，我拒絕所有對沒有域的 IP 的請求，我看不到為這些請求提供服務有任何價值。

server {
 listen      80 default_server;
 server_name _; # Wildcard, any domain is served
 return      444; # This means "go away", effectively
 access_log off; log_not_found off;
}

由於 SSL/TLS 需要有效的域名證書，我認為使用 https 不可能做到這一點。
