Three Node Install of RDO OpenStack Using PackStack

Install of distributed compute, controller and storage nodes of OpenStack

Following my single server installation of RDO OpenStack using PackStack, here is my install of OpenStack across three nodes.

What's key here is the answer files used with packstack. For a single node its trivial since you just accept nearly all the defaults.

A distributed install requires a bit of planning.

First I installed on two nodes, using packstack from one node (sudo packstack --answer-file=/root/grizzly_openstack.cfg)

The answer file for this installation is here, it specifies the location of each component: cinder on one server (.110) with this line:

# The IP address of the server on which to install Cinder
CONFIG_CINDER_HOST=10.202.183.110

and keystone, swift, nagios, nova, horizon and quantum on a second server (.29)

Initial install looked like this:

 

Now, to add a second compute (NOVA) node to the installation, I ran packstack (sudo packstack --answer-file=/root/grizzly_openstack.cfg) from the NOVA node and used this answer file.

Note that while the answer to nearly all the parameters is "n" for 'no', though installing Nova on a new compute node also requires installing Glance as follows

# Set to 'y' if you would like Packstack to install Glance
CONFIG_GLANCE_INSTALL=y
# Set to 'y' if you would like Packstack to install Nova
CONFIG_NOVA_INSTALL=y

And the dashboard reflects this architecture
