To install Eucalyptus from release packages, perform the tasks listed in this topic.

Prerequisites

  • The prerequisite hardware and software should be in place.

To install Eucalyptus from release packages

Configure the Eucalyptus package repository on each host machine that will run a Eucalyptus service:

yum install https://downloads.eucalyptus.cloud/software/eucalyptus/5/rhel/7/x86_64/eucalyptus-release-5-1.11.as.el7.noarch.rpm

Enter y when prompted to install this package.

Configure the Euca2ools package repository on each host machine that will run a Eucalyptus service or Euca2ools:

yum install https://downloads.eucalyptus.cloud/software/euca2ools/3.4/rhel/7/x86_64/euca2ools-release-3.4-2.2.as.el7.noarch.rpm

Enter y when prompted to install this package.

Configure the EPEL package repository on each host machine that will run a Eucalyptus service or Euca2ools:

yum install epel-release

Enter y when prompted to install this package.

If you are installing on RHEL 7, you must enable the Optional repository in Red Hat Network for each NC, as follows: Go to http://rhn.redhat.com and navigate to the system that will run the NC. Click Alter Channel Subscriptions . Make sure the RHEL Server Optional check-box is selected. Click Change Subscriptions .

On CentOS enable the QEMU Enterprise Virtualization repository for each NC:

yum install centos-release-qemu-ev

The following steps should be performed on each NC host machine. Install the Eucalyptus Node Controller software on each NC host:

yum install eucalyptus-node

Remove the default libvirt network. This step allows the eucanetd dhcpd server to start.

virsh net-destroy default
virsh net-autostart default --disable

Check that the KVM device node has proper permissions. Run the following command:

ls -l /dev/kvm

Verify the output shows that the device node is owned by user root and group kvm.

crw-rw-rw- 1 root kvm 10, 232 Nov 30 10:27 /dev/kvm

If your KVM device node does not have proper permissions, you need to reboot your NC host.

On each CLC host machine, install the Eucalyptus Cloud Controller software.

yum install eucalyptus-cloud

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 the UFS host machine, install the Eucalyptus Cloud Controller software.

yum install eucalyptus-cloud

(Optional) On the UFS host machine, also install the Management Console.

yum install eucaconsole

The Management Console can run on any host machine, even one that does not have other Eucalyptus services . Install the software for the remaining Eucalyptus services. The following example shows services being installed on the same host machine.

yum install eucalyptus-cluster eucalyptus-sc eucalyptus-walrus

This installs the cloud controller (CC), storage controller (SC), and Walrus Backend (Optional) services.

Your package installation is complete. You are now ready to Configure Eucalyptus .
