New to Openstack, Adding a compute node

I have installed RDO and would like to expand what we have on one node by adding more computer nodes. I have followed the instructions on the rdo site to add a compute host, but it never shows and I have no idea where to start troubleshooting.

The rdo system has a public interface that we use to connect to the front end and a private interface on a 172.16.44/22 network that connects to the compute node.

When troubleshooting any problem, the first place to look is generally in the log files for the problematic service. On your new compute node, this probably means starting with /var/log/nova/nova-compute.log.

What a new compute node needs is a keystone,mysql,AMQ So check the related parameters in nova.conf, and api-paste.ini, like

  • nova.conf: sql_connection for mysql
  • nova.conf: qpid_xxx params for amq
  • api-paste.ini: auth_xxx and admin_xxx params for keystone

Copy values from existing node

This is ansible playbook, which add Compute node to our RDO instance.

There are links in comments pointing to two sections in docs.openstack.org , which you may read up.
