解决办法
可以考虑执行下面的命令：
[root@jenkins ~]# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo
[root@jenkins ~]# rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io.key
执行上面的命令后，服务器控制台的输出为：
[root@devops-norctx-com ~]# wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo
