I follow this tutorial: http://docs.openstack.org/mitaka/inst... , can i use packstack to install 2 nodes (compute - controller).

Packstack on RDO Mitaka was not dropped yet , on Newton feature to separate Controller and Storage Server was dropped . You can do almost any multi-node deployment , except HA Controller's Cluster and Swift multi node. Just one Swift Server ( 3 replicas - yes ) on landscape.

@dbaxps: Packstack doesn't support deploy HA Controller's cluster? I want to build openstack production using packstack, my topology include 2 controller nodes (HA - with controller's serivce and network), others node will run compute. Can I use packstack to do that? Thanks

I guess RHOSP 9 is only safe choice, you might fail with attempt of TripleO Bare Metal on RDO Mitaka. TripleO Bare Metal docs go only with commercial version
Check http://tripleo.org/index.html, but it seems to be outdated even for VENV set ups

Check RDO archives starting 03/2016 regarding TripleO Bare Metal on Mitaka.

No sir, I want to install 2 node (controller - compute). install allinone make me confuse to understand.

Can you teach me install on multi nodes (controller - compute). thanks
