# java -jar jenkins.war

默认端口是8080，指定端口用命令：

java -jar jenkins.war --httpPort=9090

另外，还可以Tomcat跑Jenkins，只需要将war包放到tomcat的根目录（webapps）下，访问即可。（参考博文：https://blog.51cto.com/bigboss/2129358）

2. rpm包安装

yum方式安装，先配置repo

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

启动：

# systemctl start Jenkins

3. Jenkins-web

浏览器访问，Jenkins的默认端口8080,

http://192.168.137.111:8080

按照界面中的提示，在指定位置获取解锁密码（也是安装后分配的admin密码）

选择推荐安装：
