Description:

In this comprehensive step-by-step guide, we will show you how to set up Jenkins, the leading automation server, on your system. Jenkins is a powerful tool that facilitates continuous integration and continuous delivery (CI/CD) pipelines, making software development and deployment more efficient.

1. Install Jenkins on Ubuntu 22.04 Server:

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key |sudo gpg --dearmor -o /usr/share/keyrings/jenkins.gpg
sudo sh -c 'echo deb [signed-by=/usr/share/keyrings/jenkins.gpg] http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'

        

curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key | sudo tee \
  /usr/share/keyrings/jenkins-keyring.asc > /dev/null
        

echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null
        

sudo apt update
sudo apt install -y openjdk-17-jdk
sudo apt install jenkins
        

2. Start Jenkins Service:

sudo systemctl start jenkins.service
sudo systemctl status jenkins
        

Jenkins Service Running

3. Open Port 8080

Jenkins runs on port 8080. By default, the port is closed by firewall. We need to open it to be able to access the Web Interface.

sudo ufw allow 8080
sudo ufw status
        

Port 8080 is open

4. Accessing web interface:

We can access the web interface on http://your_server_ip_address_or_domain:8080

We need to unlock the jenkins for the first time after installation. Copy the paasword from cat /var/lib/jenkins/secrets/initialAdminPassword
