nginx 使用 ssl 重定向域

我有一個新域 (my-future-domain.com)，我試圖用它來替換我目前的域 (​​my-current-domain.com)。我在 Ubuntu 上使用 DigitalOcean Nginx 伺服器，並認為我應該採取以下步驟來用我的新域替換目前域，但我之前從未處理過域遷移，這就是為什麼我想就這些步驟提供回饋我打算拿。

**1）**將A記錄指向與目前伺服器關聯的IP，將CNAME指向A記錄

A = my-future-domain.com 指向 100.200.1.90

CNAME = www.my-future-domain.com 是 my-future-domain.com 的別名

**2)**使用 certbot 為 my-future-domain.com 和 www.my-future-domain.com 生成 SSL sudo certbot --nginx -d my-future-domain.com -d www.my-future-domain.com

3)2: Redirect - Make all requests redirect to secure HTTPS access.在 certbot 提示符下選擇

4）server_name為新域名添加新塊並模仿目前伺服器塊

目前區塊：

#This server block will redirect http:// to https://www.my-current-domain.com
server {
   listen 80;
   listen [::]:80;
   server_name my-current-domain.com www.my-current-domain.com;
   return 301 https://www.my-current-domain.com$request_uri;
}

#This server block will redirect https://my-current-domain.com to https://www.my-current-domain.com (expecting that you have a certificate for my-current-domain.com as well as www.my-current-domain.com
server {
   listen 443 ssl http2;
   listen [::]:443 ssl http2;
   include snippets/ssl-www.my-current-domain.com.conf;
   include snippets/ssl-params.conf;
   server_name my-current-domain.com;
   return 301 https://www.$server_name$request_uri;
}

新網站塊：

#This server block will redirect http:// to https://www.my-future-domain.com
server {
   listen 80;
   listen [::]:80;
   server_name my-future-domain.com www.my-future-domain.com;
   return 301 https://www.my-future-domain.com$request_uri;
}

#This server block will redirect https://my-future-domain.com to https://www.my-future-domain.com (expecting that you have a certificate for my-future-domain.com as well as www.my-future-domain.com
server {
   listen 443 ssl http2;
   listen [::]:443 ssl http2;
   include snippets/ssl-www.my-future-domain.com.conf;
   include snippets/ssl-params.conf;
   server_name my-future-domain.com;
   return 301 https://www.$server_name$request_uri;
}

**5)**將來自 my-current-domain.com 和 www.my-current-domain.com 的流量重定向到 www.my-future-domain.com。我是否從第 4 步更新“目前塊”？

**6)**刪除 my-current-domain.com 的 A 和 CNAME 記錄

有什麼我可能會失去的嗎？

DNS 看起來正確。為了簡化 DNS 請求，您可以將 my-current-domain.com 也設置為 www.my-future-domain.com 的 CNAME，而不僅僅是 www.my-current-domain.com。在舊域到期之前，您不需要刪除 DNS；將其留在原處是無害的。（它也將使任何仍然引用舊域的東西受益。重定向應該處理其餘的。）

我將按如下方式配置您的伺服器塊。

server {
       listen 80;
       listen [::]:80;
       server_name my-future-domain.com www.my-future-domain.com my-current-domain.com www.my-current-domain.com;
       return 301 https://www.my-future-domain.com$request_uri;
}

server {
       listen 443 ssl http2;
       listen [::]:443 ssl http2;
       server_name www.my-future-domain.com;
       …

您可以通過組合兩個伺服器塊來清理程式碼。

如果您追求目前的計劃，如果有人請求http://my-current-domain.com>，他們將被重定向到<https://www.my-current-domain.com然後再次重定向到https://www .my-future-domain.com。您可以通過在初始伺服器塊中執行這一切來節省重定向。
