准备环境
1、首先找到对应源的镜像网站以下参考网站都可
http://mirrors.yun-idc.com 首都
http://mirrors.aliyun.com/ 阿里云
http://mirrors.163.com/ 网易
http://mirrors.sohu.com/ 搜狐
2、目录规划 mkdir –p /data/epel （epel源包下载路径）
mkdir –p /data/yum （centos源包下载路径）
3、httpd 、rsync 工具，rsync一般系统自带，httpd可能需要下载rpm包安装
输入命令 rpm –qa | grep httpd rpm –qa | grep rsync来确认是否安装
4、准备好的epel.repo yum.repo 文件（附件）
服务器的搭建
1、以下以首都镜像网站为例部署epel源，根据centos系统版本进行下载，目前我们主要使用的是centos 7以上版本，所以下载7/
2、进入7/目录后获取URL地址
利用rsync同步到本地/data目录中
1、rsync -avrt --delete --no-iconv --bwlimit=1000 rsync://mirrors.yun-idc.com/epel/7/ /data/epel （–bwlimit 限制下载网速）
2、加入到自动化任务中每月更新一次
30 0 1 * * /usr/bin/rsync -avrt --delete --no-iconv --bwlimit=1000 rsync://mirrors.yun-idc.com/epel/7/ /data/epel
3、创建软连接apache的默认路径为/var/www/html，所以我们/data/下的软件包要想被识别就要放到/var/www/html目录下，此时创建软连接最方便
1、 ln –s /data/epel /var/www/html/epel
chmod -R 555 /data
至此服务器端完成
客户端配置
1、cd /etc/yum.repos.d 下将原有文件备份到 /etc/yum.repos.d/back
2、将编写好的epel.repo 和yum.repo放到/etc/yum.repos.d/
3、yum clean all 清除缓存
4、yum makecache 建立缓存
5、yum repolist
6、yum install nginx 测试源的可用性
至此客户端配置完成
repo文件内容如下
[root@centos7 yum.repos.d]# cat epel.repo
