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.

Set up ONOS node

1. Install ONOS
   We strongly recommend to follow the link to set the ONOS node and install the ONOS development environment : ONOS from Scratch
