OpenStack - Install

I succeeded in installation OpenStack on Sentos6.5,
But I want to stop or restart service.
I don't know that yet.

@ First, you need to install git to get the Devstack Scripts
$ yum install git
@ Make the sudo group
$ /usr/sbin/groupadd sudo

@ Add stack user and grant stack NOPASSWD
$ useradd -U -G sudo -s /bin/bash -m stack
$ echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
@ Input your password you like(openstack)
$ passwd stack

@ Change user and move the home.
$ su - stack
$ cd /home/stack
$ git clone git://github.com/openstack-dev/devstack.git

@ Create the localrc file
$ vim /home/stack/devstack/localrc
