ubuntu上codeigniter设置的htaccess问题

Question

    My website open properly when I type `www.abc.com` on browser but when I type `abc.com` it opens page of subdomain which I have hosted which is `admin.abc.com`.

    But the url still says `abc.com`

    Here is my .htaccess code:

    <!-- language: lang-bash -->

        RewriteEngine on
        RewriteBase /
        RewriteCond %{HTTP_HOST} !^www\. [NC]
        RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

    I am using Ubuntu 14.04 with Apache and have configured virtual hosts for both domains.
    Any guidance will be highly appreciated.

这是我为 abc.com 上传到服务器上的域和子域的 conf 文件。

    <!-- language: lang-bash -->
    # domain: abc.com
    # public: /var/www/abc.com/public_html/

    <VirtualHost *:443>
      SSLEngine On
      SSLCertificateFile /etc/ssl/localcerts/c8d39f3574580de6.crt
      SSLCertificateKeyFile /etc/ssl/localcerts/abc.key
      SSLCertificateChainFile /etc/ssl/localcerts/gd_bundle-g2-g1.crt

      <Directory /var/www>
      Options Indexes FollowSymLinks MultiViews
      AllowOverride All
      Order allow,deny
      allow from all
      </Directory>

      # Admin email, Server Name (domain name), and any aliases
      ServerAdmin admin@abc.com
      ServerName  abc.com
      ServerAlias abc.com

      # Index file and Document Root (where the public files are located)
      DirectoryIndex index.html index.php
      DocumentRoot /var/www/abc.com/public_html
      # Log file locations
      LogLevel warn
      ErrorLog  /var/www/abc.com/log/error.log
      CustomLog /var/www/abc.com/log/access.log Combined
    </VirtualHost>

这是 admin.abc.com 的 conf 文件

<!-- language: lang-bash -->

# domain: admin.abc.com
# public: /var/www/admin.abc.com/public_html/

<VirtualHost *:80>
  # Admin email, Server Name (domain name), and any aliases
  ServerAdmin admin@abc.com
  ServerName  admin.abc.com
  ServerAlias admin.abc.com

  # Index file and Document Root (where the public files are located)
  DirectoryIndex index.html index.php
  DocumentRoot /var/www/admin.abc.com/public_html
  # Log file locations
  LogLevel warn
  ErrorLog  /var/www/admin.abc.com/log/error.log
  CustomLog /var/www/admin.abc.com/log/access.log combined
</VirtualHost>

如果上述配置文件有助于确定问题，请告诉我们，期待您的回复。

您的虚拟主机配置是否正确配置？

如果可以的话，我建议您使用配置文件而不是 .htaccess。

（在：/etc/apache2/sites-enabled 或 sites-available，如果尚未激活） p>

<VirtualHost *:80>

        # With this configuration when you try to reach both www.abc.com
        # and abc.com it directs you to the same place.
        # If you got a subdomain, you should create a separate .conf file
        # with the correct configurations as well.

        ServerAdmin admins@email.com
        ServerName www.abc.com
        ServerAlias abc.com
        DocumentRoot /var/www/path/to/websites/folder

        # Some more comments...

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

        # More comments... 
</VirtualHost>

编辑完后，别忘了重启 Apache 服务器：

sudo service apache2 restart 

或

sudo systemctl restart apache2.service

希望对你有帮助。
