In the fast-paced world of software development, Continuous Integration (CI) and Continuous Delivery (CD) have become essential practices for ensuring the reliability and efficiency of code deployment. Jenkins, an open-source automation server, plays a crucial role in setting up robust CI/CD pipelines. In this guide, we’ll walk you through the process of setting up a CI/CD pipeline using Jenkins on Red Hat Enterprise Linux 9 (RHEL 9). Follow these step-by-step instructions to streamline your development and deployment workflows.

Before diving into the installation and configuration, make sure you have the following prerequisites in place:

  1. A running instance of RHEL 9 with administrative privileges.
  2. A stable internet connection for downloading necessary packages.

CI/CD with Jenkins on RHEL9

Begin by updating your system and installing Java Development Kit (JDK). Jenkins is built on Java, so this step is crucial.

					$ sudo dnf update
$ sudo dnf install java-11-openjdk-devel

Now, download and install the Jenkins repository key and enable the Jenkins repository:

					$ sudo wget -O /etc/yum.repos.d/jenkins.repo
$ sudo rpm --import


Install Jenkins:

					$ sudo dnf install jenkins

Start and enable Jenkins service:

					$ sudo systemctl start jenkins
$ sudo systemctl enable jenkins


Step 1: Configure Jenkins:

Access Jenkins through your web browser by navigating to http://<your-server-IP>:8080. Retrieve the initial administrator password using:

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

Follow the on-screen instructions to complete the Jenkins setup.

Step 2: Install Required Plugins

Once Jenkins is up and running, install the necessary plugins to support your CI/CD workflow. Common plugins include Git, GitHub, Docker, and Pipeline.

  1. Navigate to Jenkins dashboard.
  2. Click on “Manage Jenkins” > “Manage Plugins.”
  3. Go to the “Available” tab, search for the required plugins, and install them.

Step 3: Create a New Jenkins Job

  1. Click on “New Item” on the Jenkins dashboard.
  2. Enter a job name and select the type of project (freestyle project or pipeline).
  3. Configure the job with your source code repository, build triggers, and other settings.

Step 4: Configure CI/CD Pipeline Script

If you chose the Pipeline job type, you’ll need to define your CI/CD pipeline using the Jenkinsfile. Here’s a basic example:

					pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                checkout scm
        stage('Build') {
            steps {
                // Your build commands
        stage('Test') {
            steps {
                // Your testing commands
        stage('Deploy') {
            steps {
                // Your deployment commands


Customize the stages based on your project’s requirements.

Step 5: Save and Run Your Jenkins Job

Save your Jenkins job configuration and trigger a manual build or wait for the defined triggers to start the CI/CD pipeline.


Congratulations! You have successfully set up a CI/CD pipeline using Jenkins on RHEL 9. Implementing a robust CI/CD pipeline using Jenkins empowers development teams to deliver high-quality software at an accelerated pace. By automating the build, test, and deployment processes, teams can catch errors early, ensure consistency, and deploy updates with confidence. This automated workflow will enhance the efficiency and reliability of your software development and deployment processes. Feel free to customize and expand upon this foundation to meet the specific needs of your projects. Happy coding!
