Install Jenkins on Ubuntu steps from here . Works for me with my Ubuntu 14.04 and latest Jenkins 1.567:
Type following commands in terminal:
$ wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
$ sudo sh -c 'echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list'
$ sudo apt-get update
$ sudo apt-get install jenkins
Jenkins will install and configured to run as a daemon. Check the installation by opening http://localhost:8080 in browser
It also can be useful for further Jenkins configuration:
$ sudo usermod -G shadow jenkins
$ sudo /etc/init.d/jenkins stop
Thanks Dmitry for the effort. But somehow your article confused me. How do you enable authentication to discourage misuse of Jenkins? This good tutorial helped me to configure Jenkins global security.
