Hi

I am new to cloud and openstack. Please give detailed steps as to how i can install and configure compute node and a controller node on 2 separate host machines running on centos 7 operating system.

I have already installed openstack juno version using packstack as per the following url: https://openstack.redhat.com/Quickstart

Please suggest further steps to add a new compute node on a different host machine with details so that i can monitor the VM's created on 2nd Host Machine from my controller node.

hi dbaxps.. i hav successfully installed & configured 2 hosts Controller+Network Node && Compute Node. Now how do i deploy VM's on the Compute node and later be able to monitor them from the Controller ? Do i need to deploy the Vm's from the Controller node to the Compute node or directly on compute

Nova networking is deprecated on RDO Juno,IceHouse,Havana. Only Neutron networking , view :

Just ignore cinder backend set up with Gluster or ISCSI LVM. Set up above installs Controller && Compute via one run on Controller.
If you insist on adding procedure view :-

Launch browser to http://controller-ip/dashboard as admin or demo on Controller.
Passwords in keystonerc_admin (demo ) files.

1. Login as demo and remove external gateway to public network.
2. Login as admin and recreate public network matching your real LAN say 192.168.1.0/24 with Gateway
    matching IP or your real gateway.  Make public network shared.
3. Login as demo and create demo_network say 40.0.0.0/24 with DHCP enabled and DNS server
4. Create new router say RouterDemo
5. Create external gateway to new public && and interface to demo_network for RouterDemo.
6. Enable security rules for demo tenant
7. Create ssh-keypair
8. Try launch Cirros VM

Thanks for help. Do i run these commands only on the controller node or on both the controller as well as compute nodes ? And will i be able to monitor VM's created on compute node from the controller node by this ?

If you are going to follow http://bderzhavets.blogspot.com/2014/...
You grab answer-file from post, put on Controller ( clean ) and run just once:

packstack --answer-file=./answerTwoNode.txt

It will result two clean hosts become Controller+NetworkNode && Compute Node after successful completition of packstack. Actually, it is production style approach. You will be able monitor VMs running on Compute via dashboard on Controller.
