Introduction
Welcome, fellow enthusiasts, to the world of Jenkins! Jenkins is an open-source automation tool that helps with building, testing, and deploying software. It is a popular tool because of its extensibility and flexibility. In this article, we’ll guide you through the process of setting up a Jenkins server on the Debian operating system.
Before we delve into the details, let’s understand what Jenkins is, why we need it, and how it functions. Jenkins is a continuous integration (CI) tool that automates the building, testing, and deployment of software. It is a server-based tool that runs on a web container such as Tomcat. Jenkins works by monitoring the source code repository, and whenever new code is pushed, it triggers the build process.
Now that you have a basic understanding of Jenkins, let’s get started with the setup process.
Setting Up Jenkins Server on Debian
The installation of Jenkins on Debian is a straightforward process and can be done in a few steps.
Step 1: Adding Jenkins Repository
The first step in installing Jenkins is to add the Jenkins repository to your Debian system. To do this, you need to add the Jenkins key to your system and then add the repository.
To add the Jenkins key, use the following command:
Command |
Description |
wget -q -O – https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add – |
Downloads and adds the Jenkins key to your system |
After adding the key, add the Jenkins repository to your system using the following command:
Command |
Description |
echo deb https://pkg.jenkins.io/debian-stable binary/ | sudo tee /etc/apt/sources.list.d/jenkins.list |
Adds the Jenkins repository to your system |
Step 2: Installing Jenkins
After adding the Jenkins repository, update your system and install Jenkins using the following commands:
Command |
Description |
sudo apt-get update |
Updates your system |
sudo apt-get install Jenkins |
Installs Jenkins on your system |
After installation, start the Jenkins service using the following command:
Command |
Description |
sudo systemctl start Jenkins |
Starts the Jenkins service |
Step 3: Accessing Jenkins
By default, Jenkins runs on port 8080. To access the Jenkins web interface, open your web browser and enter the following URL:
http://your_server_IP:8080
Replace “your_server_IP” with the IP address of your server.
Step 4: Configuring Jenkins
After accessing the Jenkins web interface, you need to configure it. Follow the on-screen instructions to set up your Jenkins server.
