情景： 为内网主机搭建 yum 源，且 yum 源同步 外网的源服务器。
同步 yum 源
同步本地 yum 源有三种方式
1、 wget 方式
2、 reposync 方式
3、 raync 方式 （源站点需要支持 rsync）
# yum 源的同步站点
# http://centos.ustc.edu.cn/centos/
# 查看源列表
[root@WJ110 yum]# rsync --list-only rsync://rsync.mirrors.ustc.edu.cn/centos/6/os/x86_64/

配置 nginx
注： 打开目录浏览功能
server {
listen 80;
server_name localhost;
location / {
root /data/yum;
autoindex on; # 打开目录浏览功能
autoindex_exact_size off; # 显示出文件的大概大小，单位是kB或者MB或者GB
autoindex_localtime on; # 显示的文件时间为文件的服务器时间
}
}
重启 nginx，访问地址，可以访问到 /data/yum/ 下的目录列表
修改 yum.repo 文件
只需修改地址部分即可，如下：
[base]
name=CentOS-6 - Base - local.com
baseurl=http://172.18.50.110/centos/6/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=os
gpgcheck=1
gpgkey=http://172.18.50.110/centos/RPM-GPG-KEY-CentOS-6
#released updates
[updates]
name=CentOS-6 - Updates - local.com
baseurl=http://172.18.50.110/centos/6/updates/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updates
gpgcheck=1
gpgkey=http://172.18.50.110/centos/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-6 - Extras - local.com
baseurl=http://172.18.50.110/centos/6/extras/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extras
gpgcheck=1
