解决：更换yum源

1. 备份原有文件

[root@zk1 yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.backup

2. 下载源文件

下载centos源

[root@zk1 yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo

下载epel源

[root@zk1 yum.repos.d]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.cloud.tencent.com/repo/epel-7.repo

　3. 清除和重新生成缓存

[root@zk1 yum.repos.d]# yum clean all && yum makecache
