Install

官网：https://jenkins.io/doc/book/installing/

安装包：https://pkg.jenkins.io/

根据操作系统选择不同的pkg，这里选择的是https://pkg.jenkins.io/redhat/

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

yum install jenkins

或者
下载rpm安装包，使用rpm安装
rpm -ivh jenkins-2.7.4-1.1.noarch.rpm

This package installation will:

• Setup Jenkins as a daemon launched on start. See/etc/init.d/jenkinsfor more details.

• Create ajenkinsuser to run this service. Home -> /var/lib/jenkins

• Direct console log output to the file/var/log/jenkins/jenkins.log. Check this file if you are troubleshooting Jenkins.

• Populate/etc/default/jenkinswith configuration parameters for the launch, e.gJENKINS_HOME

• Set Jenkins to listen on port 8080. Access this port with your browser to start configuration.
