===================================
Setting Up Open Daylight Controller
===================================
For exemplary purpose, we assume:
* The hostname of Open Daylight Controller Node is ``opnfv-odl-controller``
* CentOS 7 is installed
* We use ``opnfv`` as username to login.
* Java 7 is installed in directory ``/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85-2.6.1.2.el7_1.x86_64/``
**ODL-1**: Login to Open Daylight Controller Node with username ``opnfv``.
**ODL-2**: Download the ODL Lithium distribution from
``http://www.opendaylight.org/software/downloads``
.. code-block:: bash
wget https://nexus.opendaylight.org/content/groups/public/org/opendaylight/integration/distribution-karaf/0.3.3-Lithium-SR3/distribution-karaf-0.3.3-Lithium-SR3.tar.gz
**ODL-3**: Extract the tar file
.. code-block:: bash
tar -zxvf distribution-karaf-0.3.3-Lithium-SR3.tar.gz
**ODL-4**: Install Java7
.. code-block:: bash
sudo yum install -y java-1.7.0-openjdk.x86_64
**ODL-5 (OPTIONAL)**: We are using ``iptables`` instead of
``firewalld`` but this is optional for the OpenDaylight Controller
Node. The objective is to allow all connections on the internal
private network (ens160). The same objective can be achieved using
firewalld as well. **If you intend to use firewalld, please skip this step and directly go to next step**:
.. code-block:: bash
sudo systemctl stop firewalld.service
sudo yum remove -y firewalld
sudo yum install -y iptables-services
sudo touch /etc/sysconfig/iptables
sudo systemctl enable iptables.service
sudo systemctl start iptables.service
sudo iptables -I INPUT 1 -i ens160 -j ACCEPT
sudo iptables -I INPUT -m state --state NEW -p tcp --dport 8181 -j ACCEPT # For ODL DLUX UI
sudo iptables-save > /etc/sysconfig/iptables
**ODL-6**: Open a screen session.
.. code-block:: bash
screen -S ODL_Controller
**ODL-7**: In the new screen session, change directory to where Open
Daylight is installed. Here we use ``odl`` directory name and
``Lithium SR3`` installation as an example.
.. code-block:: bash
cd ~/odl/distribution-karaf-0.3.3-Lithium-SR3/bin
**ODL-8**: Set the JAVA environment variables.
.. code-block:: bash
export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85-2.6.1.2.el7_1.x86_64/jre
export PATH=$PATH:/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.85-2.6.1.2.el7_1.x86_64/jre/bin
**ODL-9**: Run the ``karaf`` shell.
.. code-block:: bash
./karaf
**ODL-10**: You are now in the Karaf shell of Open Daylight. To explore the list of available features you can execute
``feature:list``. In order to enable Open Daylight with OpenStack, you have to load the ``odl-ovsdb-openstack``
feature.
.. code-block:: bash
opendaylight-user@opnfv>feature:install odl-ovsdb-openstack
**ODL-11**: Verify that OVSDB feature is installed successfully.
.. code-block:: bash
opendaylight-user@opnfv>feature:list -i | grep ovsdb
odl-ovsdb-openstack | 1.1.1-Lithium-SR1 | x | ovsdb-1.1.1-Lithium-SR1 | OpenDaylight :: OVSDB :: OpenStack Network Virtual
odl-ovsdb-southbound-api | 1.1.1-Lithium-SR1 | x | odl-ovsdb-southbound-1.1.1-Lithium-SR1 | OpenDaylight :: southbound :: api
odl-ovsdb-southbound-impl | 1.1.1-Lithium-SR1 | x | odl-ovsdb-southbound-1.1.1-Lithium-SR1 | OpenDaylight :: southbound :: impl
odl-ovsdb-southbound-impl-rest|1.1.1-Lithium-SR1 | x | odl-ovsdb-southbound-1.1.1-Lithium-SR1| OpenDaylight :: southbound :: impl :: REST
odl-ovsdb-southbound-impl-ui | 1.1.1-Lithium-SR1| x | odl-ovsdb-southbound-1.1.1-Lithium-SR1| OpenDaylight :: southbound :: impl :: UI
opendaylight-user@opnfv>
**ODL-12**: To view the logs, you can use the following commands (or alternately the file data/log/karaf.log).
.. code-block:: bash
opendaylight-user@opnfv>log:display
opendaylight-user@opnfv>log:tail
**ODL-13**: To enable ODL DLUX UI, install the following features.
Then you can navigate to
``http://<opnfv-odl-controller IP address>:8181/index.html`` for DLUX
UI. The default user-name and password is ``admin/admin``.
.. code-block:: bash
opendaylight-user@opnfv>feature:install odl-restconf odl-l2switch-switch odl-mdsal-apidocs odl-dlux-core
**ODL-14**: To exit out of screen session, please use the command ``CTRL+a`` followed by ``d``
**Note: Do not kill the screen session, it will terminate the ODL controller.**
At this moment, Open Daylight has been started successfully.
