More Components

27. ● Setup DevStack
○ git clone https://git.openstack.org/openstack-dev/devstack
○ Update local.conf
■ [[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
○ ./stack.sh (This is will install all basic components like Nova, Glance, Swift, Neutron)
● If everything is a success and If you get an IP to access Horizon, Your machine is ready to manage your cloud.
○ screen -x (To monitor all the different component Logs)
