1、备份系统yum源

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

2、设置阿里云yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 

3、添加EPEL源

wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-7.repo 

4、清理缓存并生成新的缓存

yum clean all  
yum makecache  

5、重新生成缓存

yum makecache

6、查看是否是阿里云配置

more CentOS-Base.repo

 

7、按个lrzsz，测试一下。

yum install lrzsz -y
