Install Jenkins on Amazon Linux (AWS)

In this article, we will see how to install Jenkins on Amazon Linux EC2 instance, before that let’s know what is Jenkins, what is its purpose and why it is the most widely used CI/CD tool

What is Jenkins: The leading open source automation server, Jenkins provides hundreds of plugins to support building, deploying and automating any project. In short, it’s a Continuous Integration server.

What is it used for ?? 

It’s a Continuous Integration tool where its tasks are to take care of Continuous Deployment/Delivery. Makes deployment a non-issue and helps you speed up your development other advantages are :

Developer time is focused on work that matters — Much of the work of frequent integrations is handled by automated build and testing systems, meaning developer time isn’t wasted on large-scale error-ridden integrations.

Software quality is improved — Any issues are detected and resolved almost immediately, keeping software in a state where it can be safely released at any time.

Faster Development – Integration costs are reduced both because serious integration issues are less likely and because much of the work of integration is automated.

Most companies who employ continuous integration use their own cloud-based continuous integration servers built on applications like Jenkins.
