<h1>All-In-One: Dedicated Hardware</h1>
|
|
<p>Things are about to get real! Using OpenStack in containers or VMs is nice for kicking the tires, but doesn't compare to the feeling you get with hardware.</p>

<h2>Prerequisites <small>Linux & Network</small></h2>
|
|
</div>
|
|
|
|
<h3>Minimal Install</h3>
|
|
<p>You need to have a system with a fresh install of Linux. You can download the <a href="https://help.ubuntu.com/community/Installation/MinimalCD">Minimal CD</a> for Ubuntu releases since DevStack will download & install all the additional dependencies. The netinstall ISO is available for <a href="http://mirrors.kernel.org/fedora/releases/18/Fedora/x86_64/iso/Fedora-20-x86_64-netinst.iso">Fedora</a> and <a href="http://mirrors.kernel.org/centos/6.5/isos/x86_64/CentOS-6.5-x86_64-netinstall.iso">CentOS/RHEL</a>. You may be tempted to use a desktop distro on a laptop, it will probably work but you may need to tell Network Manager to keep its fingers off the interface(s) that OpenStack uses for bridging.</p>
|
|
|
|
<h3>Network Configuration</h3>
|
|
<p>Determine the network configuration on the interface used to integrate your
|
|
OpenStack cloud with your existing network. For example, if the IPs given out on your network
|
|
by DHCP are 192.168.1.X - where X is between 100 and 200 you will be able to use IPs
|
|
201-254 for <b>floating ips</b>.</p>
|
|
<p>To make things easier later change your host to use a static IP instead of DHCP (i.e. 192.168.1.201).</p>

</div>
|
|
|
|
<h3>Add your user</h3>
|
|
<p>We need to add a user to install DevStack. (if you created a user during install you can skip this step and just give the user sudo priviledges below)</p>
|
|
<pre>adduser stack</pre>
|
|
<p>Since this user will be making many changes to your system, it will need to have sudo priviledges:</p>
|
|
<pre>apt-get install sudo -y || yum install -y sudo
|
|
echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers</pre>
|
|
<p>From here on you should use the user you created. <b>Logout</b> and <b>login</b> as that user.</p>
|
|
|
|
<h3>Download DevStack</h3>
|
|
<p>We'll grab the latest version of DevStack via https:</p>
|
|
<pre>sudo apt-get install git -y || yum install -y git
|
|
git clone https://github.com/openstack-dev/devstack.git
|
|
cd devstack</pre>
|
|
|
|
<h3>Run DevStack</h3>
|
|
<p>Now to configure <code>stack.sh</code>. DevStack includes a sample in <code>devstack/samples/local.conf</code>. Create <code>local.conf</code> as shown below to do the following:</p>
|
|
<ul>
|
|
<li>Set <code>FLOATING_RANGE</code> to a range not used on the local network, i.e. 192.168.1.224/27. This configures IP addresses ending in 225-254 to be used as floating IPs.</li>
|
|
<li>Set <code>FIXED_RANGE</code> and <code>FIXED_NETWORK_SIZE</code> to configure the internal address space used by the instances.</li>
|
|
<li>Set <code>FLAT_INTERFACE</code> to the Ethernet interface that connects the host to your local network. This is the interface that should be configured with the static IP address mentioned above.</li>
|
|
<li>Set the administrative password. This password is used for the <b>admin</b> and <b>demo</b> accounts set up as OpenStack users.</li>
|
|
<li>Set the MySQL administrative password. The default here is a random hex string which is inconvenient if you need to look at the database directly for anything.</li>
|
|
<li>Set the RabbitMQ password.</li>
|
|
<li>Set the service password. This is used by the OpenStack services (Nova, Glance, etc) to authenticate with Keystone.</li>
|
|
</ul>
|
|
<p><code>local.conf</code> should look something like this:</p>
|
|
<pre>[[local|localrc]]
|
|
FLOATING_RANGE=192.168.1.224/27
|
|
FIXED_RANGE=10.11.12.0/24
|
|
FIXED_NETWORK_SIZE=256
|
|
FLAT_INTERFACE=eth0
|
|
ADMIN_PASSWORD=supersecret
|
|
MYSQL_PASSWORD=iheartdatabases
|
|
RABBIT_PASSWORD=flopsymopsy
|
|
SERVICE_PASSWORD=iheartksl</pre>
|
|
|
|
<p>Run DevStack:</p>
|
|
<pre>./stack.sh</pre>
|
|
<p>A seemingly endless stream of activity ensues. When complete you will see a summary of
|
|
<code>stack.sh</code>'s work, including the relevant URLs, accounts and passwords to poke at your
|
|
shiny new OpenStack.</p>
|
|
|
|
<h3>Using OpenStack</h3>
|
|
<p>At this point you should be able to access the dashboard from other computers on the
|
|
local network. In this example that would be http://192.168.1.201/ for the dashboard (aka Horizon).
|
|
Launch VMs and if you give them floating IPs and security group access those VMs will be accessable from other machines on your network.</p>
|
|
|
|
<p>Some examples of using the OpenStack command-line clients <code>nova</code> and <code>glance</code>
|
|
are in the shakedown scripts in <code>devstack/exercises</code>. <code>exercise.sh</code>
|
|
will run all of those scripts and report on the results.</p>
