The version of Jenkins included with the default Ubuntu packages is often behind the latest available version from the project itself. To ensure the latest fixes and features, use the project-maintained packages to install Jenkins.
# Add the repository key to your system
wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add
# Append the Debian package repository address to the server’s sources.list
sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'
# Update the apt repository and install Jenkins
sudo apt-get update
sudo apt-get install jenkins
sudo systemctl start jenkins # Enable the Jenkins service to start at boot
sudo systemctl start jenkins # Start the Jenkins service
sudo systemctl status jenkins # Check the status of Jenkins service
Note: Jenkins is typically run as a standalone application in its own process. The Jenkins WAR file bundles Winstone, a Jetty servlet container wrapper, and can be started on any operating system or platform with a version of Java supported by Jenkins.
