Centos的yum源更换为国内的阿里云源

1.备份

$ mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

2.下载最新的CentOS-Base.repo 到 /etc/yum.repos.d/

CentOS 5
$ wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS 6
$ wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS 7
$ wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
系统还没下载wget可以先用电脑登陆后面的网址下载下来,然后复制代码进去

3. 运行yum makecache生成缓存

$ yum makecache
4. 更新系统
yum -y update
