OpenStack快速安装

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 ("Liberty") release.

Summary for the Impatient

** Make sure your /etc/environment is populated. In case it is not, as a suggestion, add the following content:

LANG=en_US.utf-8
LC_ALL=en_US.utf-8

Next, enter the commands:

sudo yum install -y https://www.rdoproject.org/repos/rdo-release.rpm
sudo yum update -y
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. 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.

Network: In case you are planning on having external network access to the server and instances, this is a good moment to properly configure your network settings. A static IP address to you network card and disabling NetworkManager are sound advices. If you are planing on something more fancy, you might want to check this topic about advanced networking BEFORE PROCEDING https://www.rdoproject.org/networking/neutron-with-existing-external-network/.

Step 1: Software repositories

Setup the RDO repositories:

sudo yum install -y https://rdoproject.org/repos/rdo-release.rpm

Update your current packages:

sudo yum update -y

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.

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 (e.g.: 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.
