quick openstack installation

I'm installation OpenStack on a lot of servers based on CentOS 7. Say I have 10 nova nodes. For each nodes, I have to make it Internet reachable, and use yum to install packages.

Is there a method to allow nova compute node to not have to access Internet? For example, something like YUM proxy/relay server, so that only this server need Internet access, and all openstack nodes need only to access this server from intranet.

The other option might be a easy clone disk method. So that once I have installed a nova compute node, then I can clone the disk to the rest 9 nodes, that is also acceptable. (For this option, I mean physical server rather than vm.)

Any suggestion and experience sharing? Thanks in advance!

Yes with out having internet access you can install OpenStack packages in one of the following ways:

  1. You can create a local yum repository of OpenStack packages, so that you can point your compute nodes to this machine to get OpenStack packages. ( http://www.unixmen.com/setup-local-yu... )

  2. You can install Compute packages in a single machine, then you can create clones of that image. Here you need to change the IP address in (/etc/nova/nova.conf) file.

  3. When you install a package in your repository, yum will download that package(rpm file) and store it in "/var/cache/yum/x86_64/20/" folder. You can copy these cached rpm files to new machine so that when you try to install the same package it won't go to Internet.
