In continuation of my previous blogs on DevOps tools. In this blog I would like to demonstrate on “Installation of Neo4j 3.2.6 Graph database on Ubuntu” with screen outputs for each command.
Installation of Neo4j for ubuntu
Assuming you have the Ubuntu cloud machine setup and following this session.
Step1: Install JDK
We need to install JDK before installing Neo4j.
add-apt-repository ppa:webupd8team/java
================================>
vskumar@ubuntu:~$ sudo add-apt-repository ppa:webupd8team/java
Oracle Java (JDK) Installer (automatically downloads and installs Oracle JDK7 / JDK8 / JDK9). There are no actual Java files in this PPA.
Important -> Why Oracle Java 7 And 6 Installers No Longer Work: http://www.webupd8.org/2017/06/why-oracle-java-7-and-6-installers-no.html
Ubuntu 16.10 Yakkety Yak is no longer supported by Canonical (and thus, Launchpad and this PPA). The PPA supports Ubuntu 17.10, 17.04, 16.04, 14.04 and 12.04.

Oracle Java 9 (for both Ubuntu and Debian): http://www.webupd8.org/2015/02/install-oracle-java-9-in-ubuntu-linux.html
Oracle JDK 9 is now considered stable. There are currently only 64bit builds (no other builds are available for download: http://www.oracle.com/technetwork/java/javase/downloads/index.html )

vskumar@ubuntu:~$
==================================>
Now, we need to install JDK9.
sudo apt install oracle-java9-installer
[Note: I have already installed JDK 9 in my VM before writing this blog. Hence the output is not copied].
Once the JDK is installed in your machine, check the java version as below:
$ java –version
=============================>
vskumar@ubuntu:~$
vskumar@ubuntu:~$ pwd
/home/vskumar
vskumar@ubuntu:~$ java –version
java 9.0.1
Java(TM) SE Runtime Environment (build 9.0.1+11)
Java HotSpot(TM) 64-Bit Server VM (build 9.0.1+11, mixed mode)
vskumar@ubuntu:~$
=============================>
Once the JDK is confirmed as above steps.
Now, let us start building the Neo4j setup as below steps:
Step2: for Neo4j Setup
Use the below command to install Neo4j.
wget -O – https://debian.neo4j.org/neotechnology.gpg.key | sudo apt-key add –

vskumar@ubuntu:~$
===============>
We need to use the below operations for setting up Neo4j:
Use the below pipe :
echo ‘deb http://debian.neo4j.org/repo stable/’ >/tmp/neo4j.list
=====================>
vskumar@ubuntu:~$ echo ‘deb http://debian.neo4j.org/repo stable/’ >/tmp/neo4j.list
vskumar@ubuntu:~$ cat /tmp/neo4j.list
deb http://debian.neo4j.org/repo stable/
vskumar@ubuntu:~$
====================>
Then move the below directory and check its validation:
sudo mv /tmp/neo4j.list /etc/apt/sources.list.d
================>
vskumar@ubuntu:~$
vskumar@ubuntu:~$ sudo mv /tmp/neo4j.list /etc/apt/sources.list.d

=============================>
Now, we need to update all dependencies by :
sudo apt-get update //
===================== You will see the huge output =======>
Once its done with ‘ok’ prompt, follow below step.
Now, let us install neo4j using
sudo apt-get install neo4j=3.2.6
==== See the below output =====>
