Installing the Frontend

To install a Frontend on a separate system, follow the instructions below. It's strongly recommended that you install any Node Controllers (NCs) before you install the Frontend.

To install the Frontend:

  1. Boot the target system from the Eucalyptus Faststart media. Wait for the boot screen to load. When the boot screen loads, select "Install CentOS 6 with Eucalyptus Frontend".
  2. You may be asked to check the media, to ensure that there are no data issues. You may check the media, or you may Skip to move on to the next step. You will then be asked to select language and keyboard options. (Note that Faststart instructions are currently available in English only.)
  3. Next, you will be asked for network information. For Network Interface, select your ethernet interface (usually eth0). For Mode, Static is recommended; DHCP will work in many cases, but if DHCP leases change, your Eucalyptus cloud will no longer be functional. Also enter IP address, Netmask, Default Gateway, and a list of DNS servers.
  4. Next, you will be asked to select timezone, and after that you will be asked to enter the root password for the system.
  5. Next, you will be asked for cloud configuration options. Most are defaults that you should not touch unless you are an experienced Eucalyptus administrator; see the Administration Guide for details. The one parameter you must enter here is the range of public IP addresses. New virtual instances created by Eucalyptus will receive IP addresses from within this specified range. Enter the lower and higher range of available public IP addresses, a dash between them (e.g.:
  6. Next, you will be asked for disk install options. Eucalyptus is intended to be the primary application on the system; by default, it will take up all disk space on the system. Experienced Linux admins can set up a separate partition for Eucalyptus here.
  7. At this point, the Eucalyptus installation will begin. Software will be installed, and a default Eucalyptus machine image (EMI) will be built. When this process is completed, you will be prompted to reboot the system.
  8. When the system reboots, you will be prompted to accept the license for this installation.
  9. You will now be asked to enter the IP addresses of the Node Controllers that you've previously configured. Enter the IP addresses, separated by spaces, for each NC that you'd like to control with your Eucalyptus frontend.
  10. You will now be asked to create a non-root login, and turn on NTP. Note that NTP is required for Eucalyptus to function properly.

The installation is now complete. You may ascertain that your cloud is running by clicking on the the web browser links from the Desktop.

Normally, you would download a credentials file and use it to configure the client tools. As part of the Faststart process, credentials are downloaded and pre-installed for you. These credentials are available in /root/ on your Frontend system.
