 Getting started with the Guided Tour (jenkins.io)

Installing Jenkins

sudo wget -O /etc/yum.repos.d/jenkins.repo \
    http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
sudo dnf upgrade
sudo dnf install jenkins java-devel

Start Jenkins

You can start the Jenkins service with the command:

sudo systemctl start jenkins

You can check the status of the Jenkins service using the command:

sudo systemctl status jenkins

If everything has been set up correctly, you should see an output like this:

Loaded: loaded (/etc/rc.d/init.d/jenkins; generated)
Active: active (running) since Tue 2018-11-13 16:19:01 +03; 4min 57s ago

If you have a firewall installed, you must add Jenkins as an exception. You must change YOURPORT in the script below to the port you want to use. Port 8080 is the most common. YOURPORT=8080 PERM="--permanent" SERV="$PERM --service=jenkins" firewall-cmd $PERM --new-service=jenkins firewall-cmd $SERV --set-short="Jenkins ports" firewall-cmd $SERV --set-description="Jenkins port exceptions" firewall-cmd $SERV --add-port=$YOURPORT/tcp firewall-cmd $PERM --add-service=jenkins firewall-cmd --zone=public --add-service=http --permanent firewall-cmd --reload
