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 enabled_services=q-l3

   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
   language text

4. Upgrade OVS to version 2.3.2
   Unload existing openvswitch modules

   Code Block
   language bash
   $ sudo rmmod openvswitch

   Check if openvswitch modules are unloaded.

   Code Block
   language bash
   $ sudo lsmod

   Uninstall openvswitch 2.0.2.

   Code Block
   language bash
   $ sudo apt-get remove openvswitch-common

   Then, follow the steps "Install Openvswitch" steps below.

5. Create a br-ex bridge

   The br-ex bridge is created by the devstack, but we need to create it again after installing the new openvswitch because it was removed when we remove the old version of openvswitch.

   Code Block
   language bash
   sudo ovs-vsctl add-br br-ex

Set up Compute node

1. Install Openvswitch

   Even though any version higher than 2.0 would work, but we have tested with 2.3.2.

   Code Block
   language bash
   $ wget http://openvswitch.org/releases/openvswitch-2.3.2.tar.gz $ tar xzvf openvswitch-2.3.2.tar.gz $ cd openvswitch-2.3.2/ ~/openvswitch-2.3.2$ ./configure ~/openvswitch-2.3.2$ make ~/openvswitch-2.3.2$ sudo make install ~/openvswitch-2.3.2$ sudo modprobe openvswitch

   You can check if openvswitch is loaded properly

   Code Block
   language bash
   ~/openvswitch-2.3.2$ sudo lsmod Module Size Used by openvswitch 71004 0 vxlan 37619 1 openvswitch ip_tunnel 23768 1 vxlan gre 13796 1 openvswitch libcrc32c 12644 1 openvswitch

2. Set up OVS
   Please see the following link for detail, but here are the simple way to set up the OVS.
   https://github.com/openvswitch/ovs/blob/master/INSTALL.md

   Code Block
   language bash
   ~/openvswitch-2.3.2$ mkdir -p /usr/local/etc/openvswitch ~/openvswitch-2.3.2$ sudo ovsdb-tool create /usr/local/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema ~/openvswitch-2.3.2$ sudo ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \ --remote=db:Open_vSwitch,Open_vSwitch,manager_options \ --private-key=db:Open_vSwitch,SSL,private_key \ --certificate=db:Open_vSwitch,SSL,certificate \ --bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \ --pidfile --detach ~/openvswitch-2.3.2$ sudo ovs-vsctl --no-wait init ~/openvswitch-2.3.2$ sudo ovs-vswitchd --pidfile --detach

   You can check if it is installed correctly

   Code Block
   language bash
   ~/openvswitch-2.3.2$ sudo ovs-vsctl --version ovs-vsctl (Open vSwitch) 2.3.2 Compiled Dec 3 2015 14:49:51 DB Schema 7.6.2

   Set manager as ptcp:6640 so that ONOS can detect the OVSDB

   Code Block
   language bash
   ~/openvswitch-2.3.2$ sudo ovs-vsctl set-manager ptcp:6640

3. Install devstack on the Compute node

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

4. Please use the following local.conf for the compute nodes

   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=1.1.1.1 ADMIN_PASSWORD=nova DATABASE_PASSWORD=$ADMIN_PASSWORD RABBIT_PASSWORD=$ADMIN_PASSWORD SERVICE_PASSWORD=$ADMIN_PASSWORD SERVICE_TOKEN=$ADMIN_PASSWORD DATABASE_TYPE=mysql #Images IMAGE_URLS="http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img,http://jaist.dl.sourceforge.net/project/gns-3/Qemu%20Appliances/linux-tinycore-3.4.img" # Log NOVA_VNC_ENABLED=true VNCSERVER_PROXYCLIENT_ADDRESS=$HOST_IP VNCSERVER_LISTEN=$HOST_IP SCREEN_LOGDIR=/opt/stack/logs/screen LIBVIRT_TYPE=qemu # Services ENABLED_SERVICES=n-cpu,neutron

   HOST_IP should be the IP address of the compute node host, and Controller node IP address needs to be set for other settings.

5. Set up another compute node in the same way.
