很多时候为了加速自己内部的rpm包安装速度，都会搭建自己的yum源仓库，而使用系统光盘自带的源，由于软件版本比较落后，所以不太适用，而大家都在用的阿里仓库比较好用，所以就想到了把阿里仓库的rpm全部拉到本地，并做yum仓库的定时更新。这样既能保证软件包是最新的，也能保证软件的安装速度。那么下面来具体实施，搭建自己的yum本地仓库，并定时从阿里仓库同步过来。
第一步：下载阿里镜像的repo安装包，centos6就下载6的，7的就下载7的地址：https://mirrors.aliyun.com/repo/
我们以centos7的镜像为例
- cd /etc/yum.repos.d/
- mkdir bak
- mv Centos* bak #将系统自带的源备份到bak目录下
- wget https://mirrors.aliyun.com/repo/Centos-7.repo
- cat Centos-7.repo
- # CentOS-Base.repo
- #
- # The mirror system uses the connecting IP address of the client and the
- # update status of each mirror to pick mirrors that are updated to and
- # geographically close to the client. You should use this for CentOS updates
- # unless you are manually picking other mirrors.
- #
- # If the mirrorlist= does not work for you, as a fall back you can try the
- # remarked out baseurl= line instead.
- #

已经配置好的阿里仓库
- yum repolist #查看阿里的可用仓库，有启用的表示已经成功了
- 从阿里服务器将rpm同步到本地需要两个rpm软件createrepo 和 yum-utils
- yum install createrepo yum-utils -y #yum安装这两个包
- mkdir -p /mirrors/Packege #创建rpm包的存放目录
- reposync -r base -p /mirrors/Packege #将已经配置好的阿里仓库镜像内的rpm包拉到本地,b ase为本地已经配置好的仓库名，可以用yum repolist查看到
- createrepo -pdo /mirrors/ /mirrors/Packege #创建repo数据库
###############################同步rpm包，需要相当长一段时间################################
同步完成之后，本地的yum仓库已经基本完成了，只剩下定时更新了
- vim /cron/repository.sh #编写同步脚本
- reposync -r base -p /mirrors/Packege -d #来删除本地老旧
- reposync -r base -p /mirrors/Packege
- crontab -e #添加定时任务
- 0 0 1 * * sh /cron/repository.sh #每月1日0时更新yum仓库
