If you're looking to streamline your software development process, Jenkins is an indispensable tool. With its automation capabilities, Jenkins simplifies tasks like building, testing, and deploying applications. In this guide, we'll walk through the steps to install Jenkins on an AWS Linux instance, enabling you to harness its power for your projects.
Prerequisites
Before we begin, make sure you have:
- An AWS Linux instance up and running.
- SSH access to the instance.
- Basic knowledge of Linux commands.
Step 1: Update System Packages
First, let's ensure our system packages are up-to-date:
sudo dnf update
Step 2: Install Java Development Kit (JDK)
Jenkins requires Java to run. We'll install Amazon Corretto, a no-cost, multiplatform, production-ready distribution of the Open Java Development Kit (OpenJDK).
sudo dnf install java-17-amazon-corretto -y
java -version
Verify that Java is installed correctly by checking its version.
Step 3: Add Jenkins Repository
We need to add the Jenkins repository to our system:
sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
Step 4: Import Jenkins Repository Key
To ensure the authenticity of the packages from the Jenkins repository, import the repository key:
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key
Step 5: Install Jenkins
Now, let's install Jenkins using the following command:
sudo dnf install jenkins -y
Step 6: Start and Enable Jenkins Service
Once Jenkins is installed, start the Jenkins service and enable it to start on system boot:
sudo systemctl start jenkins
sudo systemctl enable jenkins
Step 7: Access Jenkins Web Interface
Jenkins is now up and running on your AWS Linux instance. You can access its web interface using your instance's public IP address or domain name followed by port 8080 (the default Jenkins port). Open a web browser and navigate to:
http://your_instance_public_ip_or_domain:8080
Follow the on-screen instructions to complete the Jenkins setup wizard, including unlocking Jenkins and installing recommended plugins.
Conclusion
Congratulations! You've successfully installed Jenkins on your AWS Linux instance. With Jenkins configured, you're ready to automate your software development workflows, saving time and increasing efficiency in your projects.
