| 46 | <h1>Stack-in-a-Box: Try before you mkfs</h1> |
| 47 | <p>Run DevStack from a RAM disk to give it a whirl before making the |
| 48 | commitment to install it. We'll cover booting from a USB drive or |
| 49 | over the network via PXE. We'll even thow in configuring a home |
| 50 | router to handle the PXE boot. You will need a minimum of 3GB |
| 51 | for both of these configurations as the RAM disk itself is 2GB.</p> |

| 59 | <h3>USB Boot</h3> |
| 60 | <p><a href="usb-boot.html">This guide</a> covers the creation of a bootable USB drive. Your |
| 61 | computer BIOS must support booting from USB.</p> |
| 62 | |
| 63 | <h3>PXE Boot</h3> |
| 64 | <p><a href="pxe-boot.html">This guide</a> covers the installation of OpenWRT on a home router |
| 65 | and configuring it as a PXE server, plus the creation of the |
| 66 | boot images and PXE support files. |

| 73 | |
| 74 | <h3>Install DevStack</h3> |
| 75 | <p>Grab the latest version of DevStack via https:</p> |
| 76 | <pre>sudo apt-get install git -y |
| 77 | git clone https://github.com/openstack-dev/devstack.git |
| 78 | cd devstack</pre> |
| 79 | |
| 80 | <h3>Prepare the Boot RAMdisk</h3> |
| 81 | <p>Pick your boot method and follow the guide to prepare to build |
| 82 | the RAM disk and set up the boot process:</p> |
| 83 | <ul> |
| 84 | <li><a href="usb-boot.html">USB boot</a></li> |
| 85 | <li><a href="pxe-boot.html">PXE boot</a></li> |
| 86 | </ul> |
| 87 | |
| 88 | <h3>Fire It Up</h3> |
| 89 | <ul> |
| 90 | <li>Boot the computer into the RAM disk. The details will vary from |
| 91 | machine to machine but most BIOSes have a method to select the |
| 92 | boot device, often by pressing F12 during POST.</li> |
| 93 | <li>Select 'DevStack' from the Boot Menu.</li> |
| 94 | <li>Log in with the 'stack' user and 'pass' password.</li> |
| 95 | <li>Create <code>devstack/localrc</code> if you wish to change any |
| 96 | of the configuration variables. You will probably want to at |
| 97 | least set the admin login password to something memorable rather |
| 98 | than the default 20 random characters: |
| 99 | <pre>ADMIN_PASSWORD=openstack</pre> |
| 100 | </li> |
| 101 | <li>Fire up OpenStack! |
| 102 | <pre>./run.sh</pre> |
| 103 | </li> |
| 104 | <li>See the processes running in screen: |
| 105 | <pre>screen -x</pre> |
| 106 | </li> |
| 107 | <li>Connect to the dashboard at <code>http://<ip-address>/</code></li> |
| 108 | </ul> |
