• 4、配置jenkins的端口以及修改用户为root：
  [root@localhost ~]# vi /etc/sysconfig/jenkins

• 5、配置jenkins的java路径
  [root@localhost ~]# vi /etc/init.d/jenkins
  找到 candidates，里面加入你本机的实际java路径

• 6、启动jenkins
  [root@localhost ~]# systemctl enable jenkins.service
  [root@localhost ~]# systemctl daemon-reload
  [root@localhost ~]# systemctl start jenkins.service
