Jenkins setup in AWS EC2 instance

Note: Easy It is!

Installing Jenkins

sudo apt-get update

sudo apt install openjdk-8-jdk

First we need to add the repository key to the system

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -

sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > \
/etc/apt/sources.list.d/jenkins.list'

sudo apt-get update

sudo apt-get install jenkins

Open the jenkins website

http://<use the ec2 public ip>:8080/

After running this command copy the password and past it in the website and save the password in your notes

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