In this tutorial, you will learn how to setup a Jenkins Build Server on AWS EC2.
Prerequisites:
1. AWS EC2 instance is running. (Follow here).
2. Connect to your EC2 instance with SSH. (Follow here).
Steps to Download and Install Jenkins:
1. Run the following command to update all software packages on ec2 instance.
sudo yum update
2. Add the Jenkins repo using the following command:
sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
3. Import a key file from Jenkins-CI to enable installation from the package:
sudo rpm --import https://pkg.jenkins.io/redhat/jenkins.io.key
4. Install Jenkins:
sudo yum install jenkins -y
5. Start Jenkins as a service:
sudo service jenkins start
If you get the below error while starting the jenkins service, then run the following command to update java on EC2:
sudo amazon-linux-extras install java-openjdk11
Run the command again to start Jenkins service.
Jenkins is now installed and running on your EC2 instance.
Modify EC2 Security Group:
1. Go to EC2 Dashboard.
2. Go to Security Groups and select the security group associated with EC2 instance. (Ex: demo-security-group)
3. Click on Edit Inbound Rules.
4. Click Add Rule, and then choose Custom TCP Rule from the Type list. Under Port Range enter 8080.
Configure Jenkins:
1. Connect to http://<ec2-server-public-dns>:8080 from your browser. You will be able to access Jenkins through its management interface.
2. Enter the password found in /var/lib/jenkins/secrets/initialAdminPassword. Use the following
command to display this password:
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
3. The Jenkins installation script directs you to the Customize Jenkins page. Click Install suggested plugins.
4. Create a new Admin User and complete the setup.
5. Click Start Using Jenkins.
Jenkins Build Server is ready to be used on the AWS EC2 server.
