2、jenkins安装方式一
Jenkins安装方式一：war包
先安装tomcat将jenkins.war直接放到webapps目录下
通过 java -jar jenkins.war --httpPort=8080命令直接运行
官方仓库：https://pkg.jenkins.io/redhat-stable/
3、Jenkins安装方式二：rpm方式（推荐）
1
rpm -ivh jenkins-2.164.1-1.1.noarch.rpm
启动jenkins
1
/etc/init.d/jenkins start
如果是tar包安装的jdk，可能会报错，jenkins启动脚本未扫描到java,所以要手动添加jdk的安装路径
1
vi /etc/init.d/jenkins

2
systemctl daemon-reload
systemctl start jenkins
