Installing Java & Jenkins on AWS

Installing Java & Jenkins on AWS

April 27, 2020 / Nirav Shah

In this blog we will show you how to install JAVA and Jenkins on AWS ec2 running ubuntu 16.04. Before we start let us give you some ideas about java and jenkins.

Java is a general-purpose computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.

Jenkins is a free and open source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery. Jenkins is free and is entirely written in Java.

We hope now you have a basic idea about Java and jenkins, so now let’s see how to set-it up through AWS console. We assume that you have already set up an AWS account and an EC2 instance. In case you don’t know, please have a look at our blog for EC2 starter kit: How to setup EC2 instance in AWS for free.


  • You have an ec2 instance running (t2.micro will do the job here).
  • You have root access to ec2 instance.
  • In the security group you have to add port 8080 for jenkins.

In the EC2 Instance

We will gain ssh access into the instance and start configuring the instance for installation. We are going to ssh into the instance through command-line.

ssh -i private-key.pem ubuntu@ (ip-address)

And now we are able to connect to the instance. The first thing we need to do is update the packages installed on the instance as well as install some basic packages as per the requirements. First, we will update and clean the system by using following command.

sudo apt update && sudo apt upgrade -y && sudo apt autoremove -y && sudo apt autoclean

Installing Java on AWS ec2 instance running Ubuntu 16.04:

Type the following commands

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install openjdk-8-jdk

Check the java version installed

java -version

Installing Jenkins

1. First we need to add the repository key to the system

wget -q -O - | sudo apt-key add -

2. Add the following entry in your /etc/apt/sources.list

sudo sh -c 'echo deb binary/ > /etc/apt/sources.list.d/jenkins.list'

3. Now run the following commands

sudo apt-get update
sudo apt-get install jenkins

4. Go to the browser : (ip_address):8080

5. Administrator password ???

Don’t Worry just Go to the mentioned directory path using cat command in order to view the initialAdminPassword generated by default.

sudo cat /var/lib/jenkins/secrets/initialAdminPassword

Copy the generated password and paste in the “Administrator Password” section as shown above.

6. Click on the “Install suggested plugins” option

It will take time to complete…. 🙁

7. Add first admin user

Click on Save and continue.

So in the end you will get URL like this

8. Click Save and Finish

Hola Jenkins is ready….. 🙂

Go to your browser and connect to your jenkins server at default port 8080.
