下载rpm包
sudowget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
rpm包地址
https://pkg.jenkins.io/redhat-stable/
导出密钥
注意：若之前已从Jenkins导入过密钥，“rpm--import”将失败，请忽略，继续执行下面
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key
安装Jenkins
yuminstall -y jenkins
查看Jenkins信息
rpm -ql jenkins
配置Jenkins
vim /etc/sysconfig/jenkins
修改端口，默认是8080
JENKINS_PORT="端口号"
启动Jenkins
systemctl start jenkins.service
查看Jenkins状态
systemctl status jenkins.service
卸载Jenkins
#rpm卸载
rpm -e jenkins
#检查是否卸载成功
rpm -ql jenkins
彻底删除残留文件
find / -iname jenkins | xargs -n 1000rm -rf
find / -iname .jenkins | xargs -n 1000rm -rf
