The "instance" is the virtual Cloud Server that will run your infrastructure. Once you have an instance you can configure it anyway you like.

Server Name

This name will be displayed when interacting with it through the Control Panel and API. This example uses WPMaster01, shorthand for WordPress Master Server.

Give your Server a name, "WPMaster01″<br>

Region

Select the same region we used with your Cloud Databases instance (DFW). Both resources must be in the same datacenter in order to communicate. Resources in the same datacenter reside on the same private network.

Give the Server a Region, "Dallas (DFW)"<br>

Image

The Image is the operating system used to create the Cloud Server. We use the Ubuntu 12.04 LTS distribution in this walkthrough because:

• Ubuntu is widely accepted as an easy to use Linux distribution.
• Security and update management is rapid on the Ubuntu platform.
• By using a long term support (LTS) distribution, we ensure the OS will be supported well into the future.

Select the "Ubuntu 12.04 LTS (Precise Pangolin)" Image

Size

Select how much RAM and Disk to assign to your server. Our goal is to scale starting with low-power servers. We'll begin with a configuration that is smaller, but more cost effective.

Select a server size, 512MB / 30GB<br>

Networks

By default, each server is given a Public address on "Publicnet" (the public facing network available to the Internet) and a Private address on "Servicenet" (the private, internal RackSpace network available to machines physically in the same datacenter). You don't have to change anything here.

Leave the "Publicnet" and "Servicenet" Networks Selected

Click "Create Server"

When you click the Create Server button, your server goes into the build process. The image selected will be loaded onto the server and an IP address will be assigned. Once completed, the Server Status will change to "Active".

Estimated Time: This can take up to 20 minutes depending on the server size.

Let's change the server password to something you can easily remember. Make sure you are on the Cloud Servers screen in the control panel.

Click the Actions Cog and Select "Change Password"

Enter a strong password for your Cloud Server

You will use the new password when logging in via SSH through the terminal. This will be done in a moment.

You may want to use an online utility like strongpasswordgenerator to help create a strong, unique password.

To log in to your Cloud Server, you will need to use the secure shell (SSH) protocol. Open a terminal window and enter the following command, inserting the IPv4 address corresponding to the server and using the password you just set.

ssh root@192.0.2.1

Type yes to verify the identity of your Cloud Server. This will prompt the RSA key to be stored in your computers list of known hosts. This message will not be presented upon subsequent logins.
