Installation from Source

In addition to downloading the binary packages, you also have the option of compiling OrientDB from the Community Edition source code, available on GitHub. This process requires that you install Git and Apache Maven on your system.

To compile OrientDB from source code, clone the Community Edition repository, then run Maven (mvn) in the newly created directory:

$ git clone https://github.com/orientechnologies/orientdb
$ git checkout develop
$ cd orientdb
$ mvn clean install

It is possible to skip tests:

$ mvn clean install -DskipTests

The develop branch contains code for the next version of OrientDB. Stable versions are tagged on master branch. For each maintained version OrientDB has its own hotfix branch. As the time of writing this notes, the state of branches is:

• develop: work in progress for next 3.0.x release (3.0.x-SNAPSHOT)
• 2.2.x: hot fix for next 2.2.x stable release (2.2.x-SNAPSHOT)
• 2.1.x: hot fix for next 2.1.x stable release (2.1.x-SNAPSHOT)
• 2.0.x: hot fix for next 2.0.x stable release (2.0.x-SNAPSHOT)
• last tag on master is 2.2.0

The build process installs all jars in the local maven repository and creates archives under the distribution module inside the target directory. At the time of writing, building from branch 2.1.x gave:

The directory orientdb-community-2.2.1-SNAPSHOT.dir contains the OrientDB distribution uncompressed. Take a look to Contribute to OrientDB if you want to be involved.

Update Permissions

For Linux, Mac OS X and UNIX-based operating system, you need to change the permissions on some of the files after compiling from source.

$ chmod 755 bin/*.sh
$ chmod -R 777 config

These commands update the execute permissions on files in the config/ directory and shell scripts in bin/, ensuring that you can run the scripts or programs that you've compiled.
