如何切換新安裝的CentOS系統(tǒng)源為阿里云源？
1流昏、備份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2、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
3、之后運(yùn)行yum makecache生成緩存
yum clean all
yum makecache
4横缔、其他
非阿里云ECS用戶會出現(xiàn) Couldn't resolve host 'mirrors.cloud.aliyuncs.com' 信息铺遂，不影響使用。用戶也可自行修改相關(guān)配置: eg:
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
