I try RDO to install openstack on CentOS6.3, and record the steps here.

Refer URL:

Env : CentOS6.3 X86_64

Install Steps:

1. Config Repo:

a) Only leave /etc/yum.repo.d/CentOS-Base.repo, and remove other *.repo

b) yum install http://ftp.jaist.ac.jp/pub/Linux/Fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm

   Then we will have the following repo:

    -rw-r--r-- 1 root root  957 Nov  5  2012 epel.repo

    -rw-r--r-- 1 root root 1056 Nov  5  2012 epel-testing.repo

c) yum install -y http://rdo.fedorapeople.org/openstack/openstack-grizzly/rdo-release-grizzly.rpm

   Then we will have the following repo:

    -rw-r--r-- 1 root root  244 Jul 13 14:44 rdo-release.repo

2. Upgrade kernel:
