Deploying RDO is a quick and easy process. Setting up an OpenStack cloud takes approximately 15 minutes, and can be as short as 3 steps.
Below, we'll explain how to set up OpenStack on a single server. You'll be able to add more nodes to your OpenStack cloud later, if you choose.
These instructions are to install the current ("Kilo") release.
Summary for the Impatient
sudo yum update -y sudo yum install -y https://rdoproject.org/repos/rdo-release.rpm sudo yum install -y openstack-packstack packstack --allinone
Step 0: Prerequisites
Software: Red Hat Enterprise Linux (RHEL) 7 is the minimum recommended version, or the equivalent version of one of the RHEL-based Linux distributions such as CentOS, Scientific Linux, etc., or Fedora 21. x86_64 is currently the only supported architecture. See also RDO repository info for details on required repositories. Please name the host with a fully qualified domain name rather than a short-form name to avoid DNS issues with Packstack.
Hardware: Machine with at least 4GB RAM, processors with hardware virtualization extensions, and at least one network adapter.
In case your system is running with NetworkManager, you need to disable it. (See bz1117277 for discussion of why.)
Stop and disable NetworkManager:
systemctl stop NetworkManager systemctl disable NetworkManager systemctl enable network
Make sure devices are named properly for the network daemon: i.e. the following line must be present in /etc/sysconfig/network-scripts/ifcfg-<interface_name>
where <interface_name> is usually "eth0" or "em1".
Take down all interfaces (but the one via you're connected to the machine) with:
Start the network daemon:
ifdown <interface_name> && systemctl start network
Step 1: Software repositories
Update your current packages:
sudo yum update -y
Setup the RDO repositories:
sudo yum install -y https://rdoproject.org/repos/rdo-release.rpm
Looking for an older version? See http://rdoproject.org/repos/ for the full listing.
Step 2: Install Packstack Installer
sudo yum install -y openstack-packstack
Step 3: Run Packstack to install OpenStack
Packstack takes the work out of manually setting up OpenStack. For a single node OpenStack deployment, run the following command.
If you encounter failures, see the Workarounds page for tips.
If you have run packstack previously, there will be a file in your home directory named something like packstack-answers-20130722-153728.txt You will probably want to use that file again, using the --answer-file option, so that any passwords you've already set (eg, mysql) will be reused.
The installer will ask you to enter the root password for each host node you are installing on the network, to enable remote configuration of the host so it can remotely configure each node using Puppet.
Once the process is complete, you can log in to the OpenStack web interface "Horizon" by going to http://$YOURIP/dashboard. The username is "admin". The password can be found in the file keystonerc_admin in the /root/ directory of the control node.
Now that your single node OpenStack instance is up and running, you can read on about running an instance, configuring a floating IP range, configuring RDO to work with your existing network, or about expanding your installation by adding a compute node.
