php - 使用 httpd 将 www.domain.com 和 domain.com 重定向到 subdomain.domain.com

Question

我想重定向:

情况一、example.com到subdomain.example.com

情况2.www.example.com到subdomain.example.com

我已将这两段代码放入我的 httpd.conf 中。只有情况 2 有效，但情况 1 无效。

<VirtualHost *:80>
     DocumentRoot "/var/www/html/foo"
     ServerName domain.com
     ServerAlias subdomain.example.com
     <Directory "/var/www/html/foo">
                Options Indexes FollowSymLinks Includes
                Options +ExecCGI
                AllowOverride All
                Order allow,deny
                Allow from All
     </Directory>
     Redirect permanent http://example.com/ http://subdomain.example.com/
</VirtualHost>

<VirtualHost *:80>
     DocumentRoot "/var/www/html/foo"
     ServerName www.example.com
     ServerAlias subdomain.example.com
     <Directory "/var/www/html/foo">
                Options Indexes FollowSymLinks Includes
                Options +ExecCGI
                AllowOverride All
                Order allow,deny
                Allow from All
     </Directory>
     Redirect permanent / http://subdomain.example.com/
</VirtualHost>

Answer 1

我找到了答案。将example.com和www.example.com重定向到subdomain.example.com，然后只设置子域的文档根。 example.com

<VirtualHost *:80>
     ServerName example.com
     ServerAlias www.example.com example.com
     Redirect permanent / http://subdomain.example.com/
</VirtualHost>

<VirtualHost *:80>
     DocumentRoot "/var/www/html/foo"
     ServerName subdomain.example.com
     ServerAlias subdomain.example.com
     <Directory "/var/www/html/foo">
                Options Indexes FollowSymLinks Includes
                Options +ExecCGI
                AllowOverride All
                Order allow,deny
                Allow from All
     </Directory>
</VirtualHost>

通过在 httpd.conf 中使用这些代码，我能够:

1. 将 example.com 重定向到 subdomain.example.com

2. 将 www.example.com 重定向到 subdomain.example.com
