How to install and configure Two-node architecture with legacy networking (compute controller services) on openstack using packstack on centos 7 ?

anonymous user



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:

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 with Gateway
    matching IP or your real gateway.  Make public network shared.
3. Login as demo and create demo_network say 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
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.
