Installing Eucalyptus (1.5.1)
| Before you proceed with the installation, be sure to take a look at the list of Eucalyptus' prerequisites. |
A Eucalyptus cloud setup consists of three components -- the cloud controller, the cluster controller(s) and node controller(s). The cloud controller is a Java program that, in addition to high-level resource scheduling and system accounting, offers a Web services interface and a Web interface to the outside world. Cluster controller and node controller are written in C and deployed as Web services inside Apache.
Communication among these three types of components goes over SOAP with WS-security. There is one cluster controller per cluster, running on the head node; there is one node controller per each compute node. So, if you are installing Eucalyptus on one cluster, then one cloud and one cluster controller should be deployed on the head node and one node controller should be deployed on each compute node.
| If you are upgrading from a previous version of Eucalyptus, please follow the instructions in the Upgrade Document. |
Eucalyptus can be installed from source or using a set of packages (RPM and DEB). The former method is more general and should work on practically any Linux system, the latter should work on distribution which we support (at the moment Ubuntu 9.04, Debian squeeze/lenny, CentOS 5.3 and openSUSE 11). Furthermore, we have special advice for those using Rocks-based clusters.
If run into any problems, be sure to check the troubleshooting guide for solutions to commonly encountered problems.
