# 同步 CentOS6 源
mv /etc/yum.repos.d/CentOS-7.repo /etc/yum.repos.d/CentOS-7.repo.bak
reposync -r centos6-base -r centos6-updates -r centos6-extras -p /data/repo/centos6 --download-metadata --newest-only
mv /etc/yum.repos.d/CentOS-7.repo.bak /etc/yum.repos.d/CentOS-7.repo

# 同步 CentOS7 源
mv /etc/yum.repos.d/CentOS-6.repo /etc/yum.repos.d/CentOS-6.repo.bak
reposync -r base -r updates -r extras -p /data/repo/centos7 --download-metadata --newest-only
mv /etc/yum.repos.d/CentOS-6.repo.bak /etc/yum.repos.d/CentOS-6.repo

-r：指定 repo id（执行yum repolist all输出内容的第一列）

–download-metadata：同步 repodata

–newest-only：只保留最新版本，节省空间

如果没加--download-metadata，则执行：createrepo /data/repo/centos7/base
