#Jenkins is a Java application, so the first step is to install Java. Run the following command to install the OpenJDK 8 package:
sudo yum install java-1.8.0-openjdk-devel
#The next step is to enable the Jenkins repository. To do that, import the GPG key using the following curl command:
curl --silent --location http://pkg.jenkins-ci.org/redhat-stable/jenkins.repo | sudo tee /etc/yum.repos.d/jenkins.repo
#And add the repository to your system with:
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
#sudo yum install jenkins
sudo yum install jenkins
#vim /etc/sysconfig/jenkins

#修改配置
####$JENKINS_USER="root"
#change privileges
###chown -R root:root /var/lib/jenkins
###chown -R root:root /var/cache/jenkins
###chown -R root:root /var/log/jenkins

#
service jenkins restart
