The Problem #

The current version of OrientDB available as an instance on AWS Marketplace is 1.7.9. Unfortunately this version lacks a lot of the niceties and compatabilities available in later versions of OrientDB.

The Solution #

Until the folks at Orient Technologies provide an updated instance, we’ll need to do the upgrade by hand. If you haven’t already, head to the AWS Marketplace and install an instance of OrientDB.

First, SSH into the EC2 instance. Everything will be done within the instance as the root user:

sudo su root

Shut down OrientDB as it’s probably running:

/etc/init.d/orientdb.sh stop

Now, from within the /opt directory

cd /opt

Pull down the latest version (currently 2.0.5) from Orient Technologies:

wget --content-disposition -P orientdb-dist http://www.orientechnologies.com/download.php?file=orientdb-community-2.0.5.tar.gz


tar -xvvf orientdb-dist/orientdb-community-2.0.5.tar.gz

Link to /opt/orientdb, overriding the existing link to 1.7.9:

ln -s orientdb-community-2.0.5 orientdb

Add your existing user accounts to the new config (under orient-server, users):

vi -o orientdb/config/orientdb-server-config.xml orientdb-community-1.7.9/config/orientdb-server-config.xml

Set the proper permissions on the config file:

chmod 644 orientdb/config/orientdb-server-config.xml

And make sure it’s owned by the orientdb user:

chown -R orientdb.orientdb orientdb-community-2.0.5

Move the startup script for 2.0.5 into init.d:

cp orientdb/bin/orientdb.sh /etc/init.d/

And update it with the correct installation path and user:

sed -i "s|YOUR_ORIENTDB_INSTALLATION_PATH|/opt/orientdb|;s|USER_YOU_WANT_ORIENTDB_RUN_WITH|orientdb|" /etc/init.d/orientdb.sh

Finally, start OrientDB back up!

/etc/init.d/orientdb.sh start

Connecting with pyorient #

You’ll need to punch a port out of the EC2 instance to access OrientDB via the binary protocol that pyorient uses. Go to


There should be a security group called “OrientDB Community Edition”. Select “Inbound”, then “Edit”, and add the following rule:

Custom TCP Rule     TCP     2424     Anywhere

Install pyorient:

pip install pyorient

Then you should be able to connect to your instance in Python as follows:

client = pyorient.OrientDB("ec2-XX-XX-XX-XX.compute-1.amazonaws.com", 2424)
session_id = client.connect("root", password)
client.db_open("your-database-name", "root", password)
client.query("select * from V")
