Step 1: Set Up a Server on Shape.Host

Before installing Jenkins, you’ll need a server to host your environment. Here’s how to create one on Shape.Host:

Log in to Shape.Host: Visit the Shape.Host website and log in to your account. Go to the Cloud VPS section.

Create a New Server: Click on “Create” and choose the server type that fits your needs.

Shape.host Resources dashboard with Create > Instance highlighted.

Pick a Data Center: Select a data center location close to your audience for better performance.

Shape.host instance form with the data center location selector highlighted.

Choose a Plan: Pick a hosting plan that matches your project’s requirements and budget.

Set the OS: Choose Debian 12 as your operating system.

Shape.host instance form with the operating system image selector highlighted.

Launch the Server: Review your settings and click “Create Instance” Your server will be ready in a few minutes.

Shape.host instance form with the Create Instance button highlighted.

Find the Instance IP: Retrieve the public IP address of your instance from the Shape.Host dashboard.

Step 2: Connect to Your Server

Once your server is ready, connect to it using SSH. Here’s how:

  • Linux/macOS: Open your terminal and type:
  ssh root@your_server_ip

Replace your_server_ip with your server’s IP address.

  • Windows: Use an SSH client like PuTTY. Enter your server’s IP address, specify the port (usually 22), and click “Open.” Log in with your username and password.

Step 3: Update Your System

Before installing any software, update your system to ensure all packages are up to date. Run the following command:

apt update && apt upgrade -y
Terminal showing APT package management commands and output.

Step 4: Install Java

Jenkins requires Java to run. Install OpenJDK 17, a popular Java runtime, with:

apt install openjdk-17-jdk fontconfig
Terminal showing apt commands or output during Install Java.

Verify the installation:

java -version
Terminal displaying the installed Java version.

You should see output similar to:

openjdk version "17.0.8" 2023-07-18
OpenJDK Runtime Environment (build 17.0.8+7-Debian-1deb12u1)
OpenJDK 64-Bit Server VM (build 17.0.8+7-Debian-1deb12u1, mixed mode, sharing)

Step 5: Add Jenkins Repository

Jenkins provides an official repository for Debian. Add it to your system:

  1. Download the Jenkins GPG Key:
   wget -O /usr/share/keyrings/jenkins-keyring.asc https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key
  1. Add the Jenkins Repository:
   echo "deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] https://pkg.jenkins.io/debian-stable binary/" | tee /etc/apt/sources.list.d/jenkins.list > /dev/null
Terminal showing Jenkins package repository setup commands and output.
  1. Update Package Lists:
   apt update
Terminal showing Jenkins package repository setup commands and output.

Step 6: Install Jenkins

Install Jenkins using the following command:

apt install jenkins
Terminal displaying Jenkins package installation messages.

Step 7: Start and Enable Jenkins

Start the Jenkins service and enable it to run automatically on boot:

systemctl start jenkins
systemctl enable jenkins

Check the status of Jenkins to ensure it’s running:

systemctl status jenkins
Terminal showing service commands or output during Start and Enable Jenkins.

Step 8: Access Jenkins Dashboard

Jenkins runs on port 8080 by default. Open your browser and navigate to:

http://your_server_ip:8080

You’ll be prompted to unlock Jenkins. To retrieve the initial admin password, run:

cat /var/lib/jenkins/secrets/initialAdminPassword

Copy the password and paste it into the Jenkins setup page.
