The installation of Eucalyptus cloud system 4.0

I want to tell about the experience install Eucalyptus 4.0. This is the latest version of the AWS compatible cloud system Eucalyptus. Together with a large number of changes and improvements, the company changed its approach to the demo installation. From ISO it was decided to proceed to installation using Chef recipes. It is possible to reduce the system installation is ready for testing and the extension of the solution to a single command line.


All that is necessary for the full testing AWS compatible system is a minimal installation of CentOS 6.5 with 100GB of available disk space in /var.
For installation, at the command prompt to register only
bash < (curl-Ls eucalyptus.com/install)
The system will ask a few simple questions and will offer to go for coffee. After about 15 minutes (depends on the speed of your Internet connection) you have a cloud system with one uploaded image that can be immediately run.
To do this, create a key pair:
euca-create-keypair -f test test
and start the virtual machine:
euca-run-instances `euca-describe-images | grep default | awk {'print $2'}` -k test

At the moment, the Eucalyptus provides a virtual machine with the following OS installations: CentOS 6.5, CentOS 7.0, Fedora 20, Ubuntu 12.04, Debian 7, openSUSE 13. The list is constantly changing and is available along with instructions for installation and creating your own virtual machines on images.
I have used the most simple way to set by calling:
bash < (curl-Ls eucalyptus.com/install-emis)
and I set the desired OC.
Last time I already wrote how to configure a system that would increase the number of virtual machines you can run without adding new hardware. Configure Eucalyptus 3.4 is compatible with Eucalyptus 4.0.
If you need more computing power, you can add a new node by calling:
bash < (curl-Ls eucalyptus.com/install-nc)
on another machine installed with CentOS 6.5 and at least 100GB of available disk space in /var. After this it is necessary to register it in already installed system by calling:
euca_conf --register-nodes < ip of new node>

That's all that is necessary for full testing of the AWS-compatible cloud system.
