The first step in using Jenkins is installing it. In this lesson, you will learn which version of Jenkins to use for this course. The lesson will also show you how to install that version in a CentOS 7 environment. Feel free to follow along with the demonstration using a Linux Academy cloud server.
For more information on installing Jenkins, check out the documentation:
Here are the commands used in this lesson's demo:
sudo yum -y install git java-1.8.0-openjdk sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key sudo yum -y install jenkins-2.89.4 sudo systemctl enable jenkins sudo systemctl start jenkins
You can check the Jenkins log like so:
sudo tail -f /var/log/jenkins/jenkins.log
Once you install Jenkins, you will need the temporary admin password to complete setup in the browser. You can get the temporary admin password with this command:
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
