RDO Quickstart
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.
If you just want to try it out without installing anything, check out TryStack. See also Installation for alternate deployment methods.
These instructions are to install the current ("Juno") release.
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 20 or later. 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.
Fedora 21 is still in development and running RDO Juno on Fedora 21 is not recommended at this time. A separate announcement will be made on the rdo-list mailing list when RDO Juno on Fedora 21 is ready.
Hardware: Machine with at least 2GB 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.
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>
DEVICE="<interface_name>"
where <interface_name> is usually "eth0" or "em1".
Take down all interfaces (but the one via you're connected to themachine) with:
ifdown <interface_name>
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://rdo.fedorapeople.org/rdo-release.rpm
Looking for Icehouse? Use http://rdo.fedorapeople.org/openstack-icehouse/rdo-release-icehouse.rpm instead. Looking for an older version? See http://rdo.fedorapeople.org/ 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.
packstack --allinone
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.
Next Steps
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.
