PreRequisite

Install JRE if you don't have it installed

To install Java JRE, add the following Personal Package Archives (PPA):

sudo add-apt-repository ppa:webupd8team/java

Update the package database:

sudo apt-get update

Then install Oracle Java. Installing it using this particular package not only installs it, but also makes it the default Java JRE. When prompted, accept the license agreement:

sudo apt-get install oracle-java8-set-default

After installing it, verify that it's now the default Java JRE:

java -version

The expected output is as follows (the exact version may vary):

output
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

OrientDB download and installation

Download the latest community version of orientdb for Linux from here. http://orientdb.com/download/.

wget http://orientdb.com/download.php?file=orientdb-community-2.2.5.tar.gz -O /tmp/orientdb.tar.gz

Extract orientdb to /opt/orientdb

sudo mkdir -p /opt/orientdb
sudo tar xzvf /tmp/orientdb.tar.gz --strip-components=1 -C /opt/orientdb

Note: We have used 'sovrin' as user name (assuming already created), if you want to replace it with other user name, modify steps accordingly and then execute

Setup installation directory path and user name
Note: Replace in below command (with system username you want to run orientdb as) and then execute it

sudo sed -i 's/YOUR_ORIENTDB_INSTALLATION_PATH/\/opt\/orientdb/g' /opt/orientdb/bin/orientdb.sh
sudo sed -i 's/USER_YOU_WANT_ORIENTDB_RUN_WITH/<actualusername>/g' /opt/orientdb/bin/orientdb.sh

Set up users and storages section as below:
Note: There should not be any other entry with name="root", if there is comment it out or remove it.

sudo sed -i 's/<users>/<users>\n       <user name="root" password="password" resources="*" \/>\n       <user name="sovrin" password="password" resources="*" \/>/g' /opt/orientdb/config/orientdb-server-config.xml
sudo sed -i 's/<storages>/<storages>\n       <storage path="memory:temp" name="temp" userName="sovrin" userPassword="password" loaded-at-startup="true" \/> /g' /opt/orientdb/config/orientdb-server-config.xml

Validation:

count should be 1:

grep "user name=\"root\"" /opt/orientdb/config/orientdb-server-config.xml | wc -l

count should be 2:

grep "<storage" /opt/orientdb/config/orientdb-server-config.xml | wc -l

Now do :

sudo chmod 640 /opt/orientdb/config/orientdb-server-config.xml

Change owner and permissions for files in /opt/orientdb

Note: Replace and then execute

sudo chown -R <unix user name> /opt/orientdb
sudo chgrp -R <unix user name> /opt/orientdb
sudo chmod -R 744 /opt/orientdb/databases
sudo chmod 755 /opt/orientdb/bin/*.sh

Make a symlink of orientdb.sh in /etc/init.d/

sudo ln -s -f /opt/orientdb/bin/orientdb.sh /etc/init.d/orientdb

Add global config for OrientDB in ~/.sovrin/sovrin_config.py

mkdir -p ~/.sovrin

cnt=`grep "OrientDB = {" ~/.sovrin/sovrin_config.py  | wc -l`

if [ $cnt == 0 ]; then
echo '
OrientDB = {
    "user": "sovrin",
    "password": "password",
    "startScript": "/opt/orientdb/bin/server.sh",
    "shutdownScript": "/opt/orientdb/bin/shutdown.sh"
}
' >>~/.sovrin/sovrin_config.py
fi;

Start orientdb service

service orientdb start
