Openstack RDO : adding compute nodes with packstack

Here are logs when adding a compute node with RDO packstack.

There are three nodes running, one controller, one neutron and one compute.

After adding a compute node, my environment will be:

from

node	eth0 ( private )	eth1 ( public )
controller	192.168.130.101/24	192.168.131.101/24
network	192.168.130.102/24	192.168.131.102/24
compute	192.168.130.103/24	192.168.131.103/24

to

node	eth0 ( private )	eth1 ( public )
controller	192.168.130.101/24	192.168.131.101/24
network	192.168.130.102/24	192.168.131.102/24
compute	192.168.130.103/24	192.168.131.103/24
compute02	192.168.130.104/24	192.168.131.104/24

on the controller node, copy ssh key to the compute02 so that the controller node can access to the compute02 over SSH without entering password.

[root@controller ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.130.104

on the controller node, edit answer file.

[root@controller ~]# diff myanswers.txt.bak.2016092301 myanswers.txt 98c98 < CONFIG_COMPUTE_HOSTS=192.168.131.103 --- > CONFIG_COMPUTE_HOSTS=192.168.131.103,192.168.131.104
