ONOS (Open Networking Operating System) was release publicly Dec 5th -- ONOS Avocet. For details see here:
https://wiki.onosproject.org/display/ONOS/Downloads
The segment routing use case is built on an older internal release of ONOS (Sept 2014). The following instructions do not apply to ONOS 1.0.0 (Avocet), and are meant only for the SPRING-OPEN project.
Following URL has the instructions how to get started with ONOS for spring-open, starting from downloading the pre-built VM:
https://wiki.onosproject.org/display/ONOS/Installation+Guide
Using the instructions on the wiki is recommended.
The instructions below are kept only for historical purposes.
Cleanly build ONOS
$ cd ${ONOS_HOME}/
$ mvn clean compile
Required packages
$ sudo apt-get install maven python-flask python-cmd2 python-pyparsing
ZooKeeper
Download and install apache-zookeeper-3.4.6: http://zookeeper.apache.org/releases.html
By default ONOS expect ZooKeeper to be installed in ~/zookeeper-3.4.6.
This can be changed by specifing the path using ZK_HOME environment variable.
Data directory ZooKeeper uses by default is /var/lib/zookeeper. You will need to give current user permission to write to this directory.
This directory can be changed using specifying ZK_LIB_DIR environment variable and running ./onos.sh setup to generate ${ONOS_HOME}/conf/zoo.cfg.
See Configuration for details about ./onos.sh setup.
./onos.sh setup script is used to generate ONOS related configuration files. This script read configuration from "${ONOS_CONF_DIR}/onos_node.`hostname`.conf".
Copy the file "${ONOS_HOME}/conf/onos_node.conf" to match the hostname and configure the content appropriately.
Once you're done with required configuration run following to generate configuration files.
$ cd ${ONOS_HOME}/
$ ./onos.sh setup
To start ZooKeeper, and ONOS core.
$ cd ${ONOS_HOME}/
$ ./onos.sh start
To stop all the above
$ cd ${ONOS_HOME}/
$ ./onos.sh stop
You can manually start/stop individual ONOS components as follows:
Start Zookeeper
$ cd ${ONOS_HOME}/
$ ./onos.sh zk start
## Confirm Zookeeper is running:
$ ./onos.sh zk status
Start ONOS
$ cd ${ONOS_HOME}/
$ ./onos.sh core start
## Confirm ONOS is running:
$ ./onos.sh core status
Unit tests bundled with ONOS source code, can be executed by using the following:
$ cd ${ONOS_HOME}/
$ mvn test
Some of the unit tests, which take longer time to execute are excluded from the above goal. To force running all the unit tests, use the following commands:
$ cd ${ONOS_HOME}/
$ mvn test -P all-tests
To run only a subset of the unit tests, use the following commands:
$ cd ${ONOS_HOME}/
$ mvn test -Dtest=PortNumberTest
Comma and wildcards can be used to specify multiple test cases. See maven-surefire-plugin website for details.
ONOS utilizes several static analysis tools to detect programmatic and formatting errors. To run some of the analysis against the code, use the following commands:
$ cd ${ONOS_HOME}
$ mvn clean verify -P error-prone
Maven need the Internet connection to download required dependencies and plugins, when they're used for the first time.
If you need to develop ONOS in an Internet unreachable environment you may want to run the following helper script before you go offline, so that required dependencies and plugins for frequently used maven target will be downloaded to your local environment.
$ ./prep-for-offline.sh
