centos

首先备份/etc/yum.repos.d/CentOS-Base.repo

下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份)，阿里云修改文件名为 CentOS-Base-aliyun.repo

• http://mirrors.163.com/.help/CentOS5-Base-163.repo
  
• http://mirrors.163.com/.help/CentOS6-Base-163.repo
  
• http://mirrors.aliyun.com/repo/Centos-5.repo
  
• http://mirrors.aliyun.com/repo/Centos-6.repo

运行以下命令生成缓存

    yum clean all    yum makecache

Fedora

1、备份

mv /etc/yum.repos.d/fedora.repo /etc/yum.repos.d/fedora.repo.backup

mv /etc/yum.repos.d/fedora-updates.repo /etc/yum.repos.d/fedora-updates.repo.backup

2、下载新的fedora.repo和fedora-updates.repo 到/etc/yum.repos.d/

fedora

wget -O /etc/yum.repos.d/fedora.repo http://mirrors.aliyun.com/repo/fedora.repo

fedora updates

wget -O /etc/yum.repos.d/fedora-updates.repo http://mirrors.aliyun.com/repo/fedora-updates.repo

3、之后运行sudo yum makecache生成缓存
