RDO Neutron Quickstart
Deploying RDO is a quick and easy process. Setting up an OpenStack Grizzly 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.
Step 0: Prerequisites
Software: Red Hat Enterprise Linux (RHEL) 6.4, or the equivalent version of one of the RHEL-based Linux distributions such as CentOS, Scientific Linux, etc., or Fedora 18 or later. See also RDO repository info for details on required repositories. Start from a minimal installation.
Hardware: Machine with at least 2GB RAM, processors with hardware virtualization extensions, and at least one network adapter.
Step 1: Software repositories
Run the following command:
sudo yum install -y http://rdo.fedorapeople.org/openstack-grizzly/rdo-release-grizzly.rpm
or to try the Havana release:
sudo yum install -y http://rdo.fedorapeople.org/openstack-havana/rdo-release-havana.rpm
Note: For Neutron to work properly, a network namespaces-enabled kernel is required. On RHEL systems, please do an update and reboot prior to continuing.
yum -y update reboot
Due to the quantum/neutron rename, SELinux policies are currently broken for Havana, so SELinux must be permissive (and please report the SELinux AVCs as bugs, if they're not already reported) on machines running neutron services, edit /etc/selinux/config to set SELINUX=permissive.
(NOTE: In production setups, it's strongly recommended to run SELinux in enforcing mode.)
Step 2: Install Packstack Installer
sudo yum install -y openstack-packstack python-netaddr
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.
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. If the installer had to upgrade your kernel, packstack will inform you that manual reboot will be required.
Once the process is complete, you can log in to the OpenStack web interface "Horizon" by going to http://$YOURIP/dashboard. The username is "demo". The password can be found in the file keystonerc_demo in the /root/ directory of the control node.
You can find the demo network topology here: http://$YOURIP/dashboard/project/network_topology/
Now that your single node OpenStack instance is up and running, you can read on about running an instance with Neutron, configuring a floating IP range, or about expanding your installation by adding a compute node.
Note: There is currently a known issue where the IP address on the br-ex interface is not persistent across reboots. As a workaround, after rebooting re-run packstack and pass the answer file that was generated by packstack --allinone with the --answer-file= option.
If you installed the updated kernel and rebooted prior to running packstack, everything should work. If you installed the updated kernel as part of running packstack, you will need to reboot when packstack completes to boot into the new kernel. This reboot will cause br-ex to reset, so after the reboot you will need to re-run packstack as shown below:
