Jenkins Installation on CentOS

Jenkins Installation on CentOS:

To use this repository, run the following command:

sudo wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

If you've previously imported the key from Jenkins, the "rpm --import" will fail because you already have a key. Please ignore that and move on.

Make sure jdk is already installed.

Check using (java -version)

With that set up, the Jenkins package can be installed with:

yum install jenkins

Reference: https://pkg.jenkins.io/redhat-stable/

Later you need to disable firewall or add exceptions to access jenkins from network.
firewall-cmd --zone=public --add-port=8080/tcp --permanent
firewall-cmd --zone=public --add-service=http --permanent
firewall-cmd --reload
