Install Nightly Release Packages

To install Eucalyptus from nightly builds, perform the tasks listed in this topic.

Prerequisites

You should have an existing Eucalyptus deployment in a QA test or development environment.
The prerequisite hardware and software should be in place and available to Eucalyptus.

Important: Eucalyptus nightly packages are the latest Eucalyptus builds. They should be considered unstable/"bleeding edge" software and should not be installed in a production environment. In addition, upgrades from nightlies to released software are not supported.

To install Eucalyptus nightly builds:

On all host machines, run the following command:

yum install http://downloads.eucalyptus.com/software/eucalyptus/nightly/4.4/rhel/7/x86_64/eucalyptus-release-nightly-4.4-1.el7.noarch.rpm

Enter y when prompted to install this package.

On all host machines that will run either Eucalyptus or Euca2ools, run the following commands:
```
yum install http://downloads.eucalyptus.com/software/euca2ools/nightly/3.4/rhel/7/x86_64/euca2ools-release-nightly-3.4-1.el7.noarch.rpm
```
Enter y when prompted to install this package.
On all host machines, enter:
```
yum update
```
Install Eucalyptus packages. The following example shows most services being installed all on the same host machine. You can use a different host for each service.
```
yum install eucalyptus-cloud eucalyptus-cluster eucalyptus-sc eucalyptus-walrus
```
Install the backend service image package on the machine hosting the CLC:
```
yum install eucalyptus-service-image
```
This installs worker images for both the load balancer and imaging services.
On each planned NC host, install the NC package:
```
yum install eucalyptus-node
```

The nightly package installation is complete.

You are now ready to Configure Eucalyptus.
