Installing Eucalyptus Nightly Packages on CentOS 6

To install Eucalyptus nightly builds on servers running CentOS 6

On all servers, run the following commands:

yum --nogpg install -y http://downloads.eucalyptus.com/
software/eucalyptus/nightly/3.1/centos/6/x86_64/eucalyptus-release-nightly-3.1.noarch.rpm

On all systems that will run either Eucalyptus or Euca2ools, run the following commands:

yum install -y http://downloads.eucalyptus.com/software/
euca2ools/nightly/2.1/centos/6/x86_64/euca2ools-release-2.1.noarch.rpm

Install the ELRepo repository on the machine that will run Walrus:

yum --nogpg install http://downloads.eucalyptus.com/
software/eucalyptus/nightly/3.1/centos/6/x86_64/elrepo-release-6.noarch.rpm

Configure the EPEL repository:
1. Go to http://fedoraproject.org/wiki/EPEL
2. Navigate to How can I use these extra packages? and select the newest version for EPEL6.
3. Click the package link to download the RPM.
4. Install the resultant RPM package with the following command, as root:
```
rpm -Uvh epel-release-X-Y.noarch.rpm
```
On all servers, enter:
```
yum update
```

Install Eucalyptus packages. The following example shows most components being installed all on the same server. You can use different servers for each component.

yum groupinstall eucalyptus-cloud-controller
yum install eucalyptus-cc eucalyptus-sc eucalyptus-walrus

High Availability

If you are deploying HA, you must install these packages on pairs of systems. For instance, “eucalyptus-cloud” is installed on the primary CLC and the secondary CLC.

On each planned NC server, install the NC package:

yum install eucalyptus-nc

Important

If you are using VMware, you can skip this step. Eucalyptus software is not installed on these machines. They are running VMware.

Your installation is complete.

You are now ready to Configure Eucalyptus.
