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.
Pick a Data Center: Select a data center location close to your audience for better performance.
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.
Launch the Server: Review your settings and click “Create Instance” Your server will be ready in a few minutes.
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_ipReplace 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
Step 4: Install Java
Jenkins requires Java to run. Install OpenJDK 17, a popular Java runtime, with:
apt install openjdk-17-jdk fontconfig
Verify the installation:
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:
- Download the Jenkins GPG Key:
wget -O /usr/share/keyrings/jenkins-keyring.asc https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key- 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
- Update Package Lists:
apt update
Step 6: Install Jenkins
Install Jenkins using the following command:
apt install jenkins
Step 7: Start and Enable Jenkins
Start the Jenkins service and enable it to run automatically on boot:
systemctl start jenkins
systemctl enable jenkinsCheck the status of Jenkins to ensure it’s running:
systemctl status jenkins
Step 8: Access Jenkins Dashboard
Jenkins runs on port 8080 by default. Open your browser and navigate to:
http://your_server_ip:8080You’ll be prompted to unlock Jenkins. To retrieve the initial admin password, run:
cat /var/lib/jenkins/secrets/initialAdminPasswordCopy the password and paste it into the Jenkins setup page.
Step 9: Complete Jenkins Setup
Follow the on-screen instructions to complete the Jenkins setup:
Install Suggested Plugins: Jenkins will install a set of recommended plugins.
Create an Admin User: Set up your admin account with a username and password.
Start Using Jenkins: Once the setup is complete, you’ll be redirected to the Jenkins dashboard.
