centos7 安装用yum命令安装wget无法安装

在终端执行yum -y install wget时，终端提示：

已加载插件：fastestmirror

Loading mirror speeds from cached hostfile

There are no enabled repos.

Run “yum repolist all” to see the repos you have.

To enable Red Hat Subscription Management repositories:

subscription-manager repos --enable

To enable custom repositories:

yum-config-manager --enable

解决方法

在终端运行curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

再运行安装命令：yum -y install wget即可
