wget和yum下载慢，更换阿里镜像源

1.安装wget

yum install -y wget

2.完事前都做备份

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

3.下载阿里云镜像文件

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

 

4.清理缓存

yum clean all

5.生成缓存

yum makecache

6.更新最新源设置

yum update -y
