Pre-requisites
I generally prefer to set all the password fields in my answer file to a predefined value. I do this using a simple regex search & replace call. You can use the same in your setup.
Note
- CentOS 6.5 (or above) installed on a system with Openstack recommended specs
 - Basic Network Configured and working. If you have used CentOS minimal version then you will need to configure the network manually. You can refer to the steps required here
 
- yum update -y
 - Go to IceHouse Repo and copy the link to the latest *****.noarch.rpm. As of December 2014, the latest rpm is : rdo-release-icehouse-4.noarch.rpm
 - yum install -y https://repos.fedorapeople.org/repos/openstack/openstack-icehouse/**latest**.noarch.rpm
 - yum install openstack-packstack
 - Generate an answer file and configure it as per your requirements
 - packstack --gen-answer-file *filename*
 - Trigger installation using the generated answer file
 - packstack --answer-file *filename*
