Linux系統下yum源配置（Centos 6）

一、備份

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

二、下載新的CentOS-Base.repo 到/etc/yum.repos.d/

CentOS 6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

或者

curl -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

或者

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

三、以後運行yum makecache生成緩存。

四、配置epol源。安裝阿里雲的epol源

a、備份(若有配置其餘epel源)

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

mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup

二、下載新repo 到/etc/yum.repos.d/

epel(RHEL 7)

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

epel(RHEL 6)

wget-O/etc/yum.repos.d/epel.repohttp://mirrors.aliyun.com/repo/epel-6.repo
