Setup OrientDB 3.0.0.m2 on Ubuntu 16.04

OrientDB is an open source NoSQL database management system written in Java. It is a multi-model database, supporting graph, document, key/value and object models but the relationships are managed as in graph databases with direct connections between records. It supports schema-less, schema-full and schema-mixed modes. It has a strong security profiling system based on users and roles and supports querying with Gremlin along with SQL extended for graph traversal.

OrientDB uses several indexing mechanisms based on B-tree and Extendible hashing, the last one is known as “hash index”.

Prerequisite

Install java 8 as pre-requisite for OrientDB. Add Oracle Java PPA to your system before proceeding with the installation of Java.

$ sudo add-apt-repository -y ppa:webupd8team/java 
$ sudo apt-get update 
$ sudo apt-get -y install oracle-java8-installer

krishna@Ubuntu:~$ java -version
java version "1.8.0_144"
Java(TM) SE Runtime Environment (build 1.8.0_144-b01)
Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)
krishna@Ubuntu:~$

Install

Download OrientDB tar file from the site OrientDB (wget http://orientdb.com/download.php?file=orientdb-community-tp3-3.0.0m2.tar.gz&utm_source=Labs&utm_medium=link&utm_campaign=300) site and extract to /opt location on unix. Installation is pretty simple download, extract and run.

By default 2G of memory is allocated to Java Virtual Machine for smooth running of OrientDB. We can still deploy with lesser memory, edit the file bin/server.sh and make the necessary changes.

# tar -zxvf orientdb-community-tp3-3.0.0m2.tar.gz
# ln -s orientdb-community-tp3-3.0.0m2 orientdb
# cd orientdb

Replace the below line in bin/server.sh
ORIENTDB_OPTS_MEMORY="-Xms2G -Xmx2G"
with 
ORIENTDB_OPTS_MEMORY="-Xms256m -Xmx512m"

# tar -zxvf orientdb-community-tp3-3.0.0m2
# ln -s orientdb-community-tp3-3.0.0m2 orientdb 
# cd orientdb 

Replace the below line in bin/server.sh 
ORIENTDB_OPTS_MEMORY="-Xms2G -Xmx2G" 
with 
ORIENTDB_OPTS_MEMORY="-Xms256m -Xmx512m"

Now, access the OrientDB using the below URL.

http://localhost:2480 or http://<IP Address>:2480

Conclusion:

We have successfully setup OrientDB.

Enjoy !!!
