=== Installing from Zip

Installing from zip is an easy way to get started with OpenDaylight. When installing from zip, the process is as simple as running the completely packaged environment. However unlike official distribution packages OpenDaylight will have to be upgraded manually after each release when installing from zip files.

==== Prerequisites

In order to be able to install and run the zip file the following prerequisites have to be fulfilled:

* A Java 1.7 compatible JDK or JRE have to be installed (i.e. Oracle JDK 1.7 or OpenJDK 1.7)
In general, OpenDaylight requires appropriate setting of the JAVA_HOME directory
More information can be found in the OpenDaylight Hydrogen Release Notes
On some platforms, there are known issues with Oracle Java 1.7.0_21 and 1.7.0_25, but 1.7.0_45 and 1.7.0_51 have worked fine

==== Getting the Zip File

You can find the OpenDaylight Hydrogen Release Base Edition zip file on the download page here:

User: admin
Password: admin
If you are running OpenDaylight on the same machine as your browser, you can browse to http://localhost:8080 or http://127.0.0.1:8080 to avoid needing to know the IP address of the machine you are using.
You will now have a completely running OpenDaylight installation.
