首先下载最新版本的jenkins包，下载地址推荐镜像：

wget https://mirrors.huaweicloud.com/jenkins/war/2.381/jenkins.war

然后创建一个 systemd 文件来配置 jenkins 服务

vi /usr/lib/systemd/system/jenkins.service

jinkins.service 文件内容

[Unit]
Description=Jenkins Continuous Integration Server
Requires=network.target
After=network.target

[Service]
Environment="JENKINS_HOME=/opt/jenkins"
Type=notify
NotifyAccess=main
ExecStart=java -Dhudson.model.DownloadService.noSignatureCheck=true -jar /opt/software/jenkins/jenkins.war
Restart=on-failure
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

注意这个JVM配置比较重要，标识不让下载插件过程中，去校验SSL

-Dhudson.model.DownloadService.noSignatureChec=true

启动jenkins

systemctl deamon-reload
systemctl start jenkins

查看启动日志,获取初始的admin密码

journalctl -efu jenkins

访问jenkins，并修改初始密码：
