when you install open-stack on a server and you want to expand a compute node, it is simple, just install nova-compute in the new machine and do some configure, then it done! following my steps:

step 1:

root@:apt-get install ntp bridge-utils
root@:vim /etc/ntp.conf
# before server ntp.ubuntu.com, insert ip with your control node ip
server $CONTROL_NODE_IP
root@:service ntp restart
root@:apt-get install nova-compute

you may need psycopg2 module, if you cannot run nova-compute successfully, or just be sure:

root@:apt-get install python-psycopg2

step 2:

root@:vim /etc/nova/nova.conf

everything just like the original server you have, except:

# overwrite the following arguments with you real environment
--vncserver_proxyclient_address=$COMPUTE_NODE_IP
--vncserver_listen=$COMPUTE_NODE_IP
root@:vim /etc/nova/api-paste.ini
#overwrite the 3 lines in the bottom, put the value associated with your configure
admin_tenant_name = some_tenant
admin_user = some_user
admin_password = your_password

step 3:

root@:service nova-compute restart
