wget和yum下載慢，更換阿里鏡像源

1.安裝wget

yum install -y wget

2.完事前都做備份

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

3.下載阿里雲鏡像文件

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

 

4.清理緩存

yum clean all

5.生成緩存

yum makecache

6.更新最新源設置

yum update -y
