需要工具：
centos7
nginx
rsync
新建文件夹存放镜像数据
mkdir /data
mkdir /data/yum_data
同步数据
国内开源镜像站没有几个支持rsync，科技大学的支持而且速度也很快
yum install -y rsync rsync-av
rsync://rsync.mirrors.ustc.edu.cn/centos/7/data/yum_data/centos/7
节省空间的同步
rsync -av rsync://rsync.mirrors.ustc.edu.cn/centos/7/os/x86_64/
/data/yum_data/centos/7/os/x86_64/
rsync-av rsync://rsync.mirrors.ustc.edu.cn/centos/7/extras/x86_64//data/yum_data/centos/7/extras/x86_64/
rsync-av rsync://rsync.mirrors.ustc.edu.cn/centos/7/updates/x86_64//data/yum_data/7/updates/x86_64/
epel源
rsync-av rsync://rsync.mirrors.ustc.edu.cn/epel/7/x86_64//data/yum_data/epel/7/x86_64/
可以把命令加入计划任务定时同步
配置web服务
yum installnginx
vim /etc/nginx/nginx.conf
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name 192.168.100.100;
root /usr/share/nginx/html;
root
/data/yum_data
修改默认根目录
autoindex on;
开启目录浏览
autoindex_localtime on;
autoindex_exact_size on;
:wq
systemctl start nginx && systemctl enablenginx
依赖关系
yum install-y createrepo
createrepo -pdo /data/yum_data/ /data/yum_data/
