yum国内镜像配置

yum默认链接的还是国外的镜像,速度相对不理想,配置成国内的镜像会快很多,这里以阿里镜像为例进行配置:

CentOS系统更换软件安装源

base源
第一步:备份你的原镜像文件,以免出错后可以恢复。
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
第二步:下载新的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

epel源

Epel 5
wget -O /etc/yum.repos.d/epel-5.repo http://mirrors.aliyun.com/repo/Cepel-5.repo
Epel 6
wget -O /etc/yum.repos.d/epel-6.repo http://mirrors.aliyun.com/repo/epel-6.repo

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


第三步:运行yum makecache生成缓存

yum clean all
yum makecache
