1. Install devstack on the Openstack Network node

   Code Block
   language bash
   $ git clone git://github.com/openstack-dev/devstack.git

2. Creates local.conf file using the following options

   Code Block
   language text
   [[local|localrc]] HOST_IP=2.2.2.2 SERVICE_HOST=1.1.1.1 RABBIT_HOST=1.1.1.1 DATABASE_HOST=1.1.1.1 Q_HOST=2.2.2.2 ADMIN_PASSWORD=nova DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD SERVICE_TOKEN=$ADMIN_PASSWORD DATABASE_TYPE=mysql # Log SCREEN_LOGDIR=/opt/stack/logs/screen # Images IMAGE_URLS="http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img" LIBVIRT_TYPE=qemu #vnc NOVA_VNC_ENABLED=True VNCSERVER_PROXYCLIENT_ADDRESS=$HOST_IP VNCSERVER_LISTEN=$HOST_IP # Services disable_service q-svc disable_service q-agt enable_service q-l3 disable_service n-cpu disable_service n-net disable_service n-cpu disable_service tempest disable_service c-sch disable_service c-api disable_service c-vol

   We need to specify the Network node IP address in HOST_IP and Q_HOST, and the Control node IP address in others. Also, we just need to enable L3 service. Later, when OpenstackRouter app is implemented, Network node itself will not be necessary.

3. Install devstack

   Code Block
   language bash
   ~/devstack$ ./stack.sh

   When it is installed successfully, you will see the message below.

   Code Block
