Login to AWS console and select Service
Click on Launch instance
Select the OS/AMI of the server (in our case we have selected Ubuntu)
Choose the instance type & click on Next
Configure instance details & click on Next
Add Storage & click on Next
Add tags (In our case, key: Name and value: Java-Program this will help to identify the instance) & click on Next
Configure Security Group (Please make sure you have SSH port 22 open in the security group) & click on Next
Review instance Launch & click on Launch
Select an existing key pair or create a new key pair & Click on launch instance
If you are fairly new to AWS environment, you should know “how to launch an EC2 instance in AWS”.
SSH into the server
$ chmod 400 new_keypair.pem #if you have a new key pair $ ssh -i new_keypair.pem ubuntu@public_ip_address
By update and upgrading the server you will get the latest packages and versions to install in the server.
$ sudo apt update && sudo apt upgrade -y
install the default Java Runtime Environment (JRE), which will install the JRE from OpenJDK.
$ sudo apt install default-jre
You may need the Java Development Kit (JDK) in addition to the JRE in order to compile and run some specific Java-based software.
$ sudo apt install default-jdk
To verify that java has installed completely
$ java -version
And it’s done. Since Java is already installed, you might want to know about how to install Jenkins in Ubuntu on an AWS server.
