OpenStack Havana - Add Compute Nodes2013/11/25 |
|
Add Compute Nodes to run more instanes.
The example below shows to configure a Compute Node on another Computer from Control Node.
|
|
| [1] |
Install KVM Hypervisor first which
needs on Compute Node. It's unnecessarry to set Bridge networking on the section [3] of the link.
|
| [2] | Install Nova-Compute, Nova-Network |
|
# add OpenStack Havana repository first root@node01:~# aptitude -y install nova-network nova-compute-kvm python-novaclient
|
| [3] | Configure Nova |

| [4] | Make sure services are working normally. It's OK if the status of services are like follows. |
