1.下载安装包
官网红帽稳定版：
Redhat Jenkins Packages
https://pkg.jenkins.io/redhat-stable/

wget -O /etc/yum.repos.d/jenkins.repo https://pkg.jenkins.io/redhat-stable/jenkins.repo --no-check-certificate

sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key

安装依赖

yum install jenkins

#找到Jenkins的war包代表安装成功了

ll /usr/lib/jenkins/

2.修改配置
修改端口号

vim /etc/sysconfig/jenkins 

#修改Jenkins端口
JENKINS_PORT="xxxx"

service jenkins start

3.登陆Jenkins

cat  /var/lib/jenkins/secrets/initialAdminPassword 找到密码

4.启动报错

vi /etc/init.d/jenkins

添加java配置

执行 systemctl daemon-reload 命令重新加载配置文件
执行 sudo service jenkins start 命令启动Jenkins
执行 systemctl status jenkins.service 命令查看Jenkins服务的状态

5.卸载
1、rpm卸载
rpm -e jenkins

2、检查是否卸载成功
rpm -ql jenkins 

3、彻底删除残留文件：
find / -iname jenkins | xargs -n 1000 rm -rf
