This document provides instructions for installing the latest OpenStack code using DevStack with either Nova network or Neutron network. The instructions include downloading DevStack, adding a stack user, giving permissions to the DevStack folder, and running stack.sh to install with Nova network. Alternatively, a local.conf file can be created to specify configuration options for installing with Neutron network instead.

1. INSTALL OPENSTACK LATEST CODE WITH DEVSTACK:
1. Download DevStack
git clone https://git.openstack.org/openstack­dev/devstack
2. Add Stack User
devstack/tools/create­stack­user.sh; su stack
3. Give stack user permission to devstack folder
chown ­R stack:stack <path to devstack folder>
4. Start the install.
cd devstack; ./stack.sh
Note: Above will install Latest Openstack code with nova­network
5. Do not execute step 4. To have Openstack deployed with neutron, create local.conf
file with below contents.
