Image description

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.

Step 1: Launching an Amazon Linux EC2 instance

[Refer video β€œHow to launch an Amazon Linux ec2 Instance”]

Step 2: Installation of Jenkins on EC2 Instance

i. Run the command to update all the packages.

sudo yum update

ii. Check if java is installed or not using the command

java -version

If java is not installed, install using the following command

sudo yum install java-1.8.0-openjdk

iii. Now, to download the latest Jenkins package

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat/jenkins.repo

**iv. **To enable the installation of the package, import the key file from Jenkins-CI:

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

v. Install Jenkins on the EC2 instance

sudo yum install jenkins

vi. To start the Jenkins service

sudo service jenkins start

vii. Access the Jenkins server using the public DNS of the EC2 instance or public IP of the instance on port 8080.

http://{ec2-public-dns}:8080 or http://3.89.79.74:8080/

viii. Login using the username admin and to get the initial admin password execute the following command:

The above steps are not working. At the end of the installation, I am unable to start the jenkins service on the EC2 (amazon linux) server. See the errors below:

If anyone already faced and resolved the issue, then pls share. Thanks in advance.
