I tried the following ways but not working for me http://answers.bitnami.org/questions/580/multiple-domains-on-bitnami-wordpress-for-amazon-ec2
both domain name pointing to the same site even though I've set the documentroot differently one is located in /opt/bitnami/apache2/htdocs/nwp and one site is located in /opt/bitnami/apps/wordpress/htdocs/
both using 1 ec2 with 1 elastic IP and in my godaddy domain name I've setup my host @ my elastic ip
and both domain name point to site1 only..
