Jenkins provides CI/CD functionality, making sysadmin and developer lives easier. See how to install and set up this useful service on an AWS Linux VM instance.

1. Spin Up An AWS Instance

On your EC2 Dashboard, spin up a new t2.medium instance with a RedHat Linux 8/9 HVM at 4GB of RAM space. Create a Security Group and Open the required ports, 8080 for Jenkins. Once the instance is set up, SSH into the instance from your IDE and proceed to download dependencies.

2. Download Dependencies

CD into the /opt directory; which is reserved for the installation of third party software

cd /opt

install java, git, tree, unzip and wget

sudo yum -y install unzip wget tree git

install java cookie

sudo wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.rpm

sudo yum install jdk-8u131-linux-x64.rpm -y

3. Add Jenkins Repository and Key

Import Jenkins Repository for RedHat

sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

CD to /etc/yum.repos.d/

sudo cd /etc/yum.repos.d/

Save file link in the above directory

sudo curl -O https://pkg.jenkins.io/redhat-stable/jenkins.repo

4. Install Jenkins

sudo yum -y install jenkins --nobest

Start the Jenkins Service

sudo systemctl start jenkins

Enable Jenkins Service

sudo systemctl enabl jenkins

5. Check Jenkins Status

sudo systemctl status jenkins

Now you should have your Jenkins successfully
installed!!
