在httpd.conf裡新增如下內容：

<VirtualHost *:80>  
DocumentRoot "/var/www/html"#域名繫結的目錄
ServerName piaocoder.com  
	<ifModule mod_rewrite.c>  
		RewriteEngine On  
		RewriteCond %{HTTP_HOST} ^piaocoder.com [NC]  
		RewriteRule ^/(.*)$ http://www.piaocoder.com/$1 [L,R=301]  
	</ifModule>  
	ErrorLog "logs/piaocoder.com-error_log"  
	CustomLog "logs/piaocoder.com-access_log" common  
</VirtualHost>
#以上piaocoder.com替換成相應的域名即可
