my subdomain is whitelotus.tibinfotech.com is pointing to main domain tibinfotech.com even after setting up virtual host.

DNS settings for subdomain as :

A record

whitelotus : IP address

CNAME

*.whitelotus : whitelotus.tibinfotech.com.

document directory path is /var/www/whitelotus.tibinfotech.com/public_html

virtual hosting settings is:

ServerName whitelotus.tibinfotech.com
ServerAlias whitelotus.tibinfotech.com

    ServerAdmin: email address
    DocumentRoot /var/www/whitelotus.tibinfotech.com/public_html

i restart the apache after setting is done. still i couldn't link subdomain to subfolder whitelotus.tibinfotech.com's public_html.
