Jenkins is an opensource and free tool for developers to develop, test and deploy the code continuously. It is developed in Java. Main benefit of Jenkins is to automate the task which helps to save the developer time in development process.

Following are the steps to install Jenkins on Centos 7.

  1. We will Install JAVA 8 to use Jenkins function.

    # sudo yum install java-1.8.0-openjdk-devel
  2. Verify the JAVA Version.

    # java --version
  3. Add Jenkins repository on centos with the below command.

  6. Start the Jenkins and enable the Jenkins service to start on system boot. # sudo systemctl enable jenkins

    # sudo systemctl start jenkins 
    # sudo systemctl enable jenkins

    # sudo firewall-cmd --permanent --zone=public --add-port=8080/tcp # sudo firewall-cmd --reload
  8. Open Jenkins in Web-browser with IPAddress:8080. We will setup Jenkins further.

    # sudo cat /var/lib/jenkins/secrets/initialAdminPassword
