You shouldconfigure your DNS zone files in such a way that they point (for example www host)to the IP address of your web server. You should also configure your apache webserver to the server-specified directory as the home page of the specified host.To enable name-based virtual hosting, you should first modify your httpd.conf fileand uncomment the following line:NameVirtualHost *:80This will enable the functionality. Now you should add appropriate configurationclauses, for each host, to your configuration file. In this example, we have usedApache 2.0 that supports the external configuration files into httpd.conf. Hence,you will not need to modify the httpd.conf file for each virtual host. Instead youcan create a file, for example, example.com.conf, under the Includes directorywhich is under your apache configuration directory. Apache will automaticallyinclude all files with a .conf extension from the Includes directory and append itto the main configuration, during startup. The sample configuration file (for example/usr/local/etc/apache2/Includes/example.com.conf) looks like this:ServerAdmin admin@example.comDocumentRoot /usr/local/www/example.comServerName www.example.comServerAlias example.comErrorLog /var/log/example.com-error_logCustomLog /var/log/example.com-access_log common[ 229 ]
