Apache2重定向到主服务器而不是确切的服务器名

Question

我的网站（生产和分期）都托管在Apache服务器（IP-12.345.456.678）中

DNS映射 12.345.456.678-www.site1.com ， 12.345.456.678-staging.site1.com

我现在需要将托管在不同apache服务器（IP-87.65.654.​​321）中的另一个站点（产品和登台）重定向到上面，以便我可以关闭此服务器。

DNS映射 87.65.654.​​321-www.site2.in ， 87.65.654.​​321-staging.site2.in

因此，我要做的是将 staging.site2.in 中的DNS映射到 12.345.456.678 。

截至目前，它正在重定向到“ www.site1.com”，而不是“ staging.site1.com”

我启用了如下所示的新配置文件，但仍然无法重定向。

<VirtualHost *:80>
   ServerName staging.site2.in
   Redirect permanent / https://staging.site1.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName staging.site2.in
    DocumentRoot /var/www/html/site1staging

    <Directory /var/www/html/site1staging>
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

    Protocols h2 h2c http/1.1

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

Ubuntu-16.04，Apache服务器-v2.4
