Muliple compute node installtions

Asked by Angel

Hi..!

I am doing cactus multiple node installation using deploy.conf. But in installation doc, http://wiki.openstack.org/NovaInstall/NovaDeploymentTool#Installing_Nova_on_Multiple_Servers_by_using_the_Nova_Deployment_Tool,, i noticed that """ When you use Cacus release, nova-compute should be installed into the same machine with nova-objectstore. "". So here i want to know if i am configuring 2 compute controller servers, then do i need to install object store on both servers or on any one of it ?

In current status, if using nova-objectstore, due to the bug in nova you
cannot run instance on the nova-compute which is installed on different
machine from nova-objectstore..

And even if you install multiple nova-objectstores, because you cannot
add the same image to all nova-objectstores, I think the method cannot
be used.

According to the answer from nova, in order to solve the problem, the
method using glance other than nova-objectstore is recommended. I
will show the steps below using glance after finished installation by
nova-deploymento-tool.

1. Install glance on <glance_server>
sudo add-apt-repository ppa:glance-core/trunk
sudo apt-get update
apt-get install glance -y

2. Add settings to /etc/nova/nova.conf on all the machines
--image_service=nova.image.glance.GlanceImageService
--glance_host=<glance_server>

3. Restart nova-compute and nova-api on all the machines
service nova-compute restart
service nova-api restart
