1，使用nginx 搭建一个web系统并显示文件目录并让这台机器可以上外网，虚拟机即可，系统centos7.9 ，硬盘容量需要至少1T以上
2，编写yum的同步脚本，我选择从科技大学源同步
3，创建centos6和7的目录和epel源同步基本的包，
一，搭建nginx 服务web显示linux目录
下载nginx http://nginx.org/en/download.html
安装依赖
#sudo yum -y install wget zlib zlib-devel openssl openssl-devel make pcre pcre-devel gcc gcc-c++ libtool
#wget http://nginx.org/download/nginx-1.18.0.tar.gz
#tar -zxvf nginx-1.18.0.tar.gz -C /opt
#cd /opt/
#./configure --prefix=/usr/local/nginx
可选##--prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_stub_status_module --with-http_gzip_static_module --with-http_realip_module --with-pcre
#make && make install
检查nginx版本/usr/local/nginx/sbin/nginx -V
设置环境变量
#export PATH=$PATH:/usr/local/nginx/sbin/
检查nginx配置 nginx -t
启动nginx nginx
关闭nginx nginx -s stop
查看nginx状态 ps auxfww|grep nginx netstat -tulnp|grep nginx
使用systemctl 管理nginx /usr/lib/systemd/system/nginx.service
[Unit]
Description=nginx
After=network target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
[Install]
WantedBy=multi-user.target
这只nginx web，vim /usr/local/nginx/conf

二，同步脚本，用于同步centos6和centos7以及epel源
[root@SVR-yum2 backup]# cat rsync.sh
#!/bin/bash
# 此脚本用于同步"#
# 如果还需要其它系统那么直接往后面加上去及要
# add centos repo
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/epel/8/Modular/ /backup/yum/epel/8/Modular &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/epel/8/Everything/ /backup/yum/epel/8/Everything &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/epel/7/x86_64/ /backup/yum/epel/7/x86_64 &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/7/extras/x86_64/ /backup/yum/centos/7/extras/x86_64 &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/7/updates/x86_64/ /backup/yum/centos/7/updates/x86_64 &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/7/os/x86_64/ /backup/yum/centos/7/os/x86_64 &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/7/centosplus/x86_64/ /backup/yum/centos/7/centosplus/x86_64 &&
rsync -avrt rsync://mirrors.ustc.edu.cn/centos/7/sclo/x86_64/ /backup/yum/centos/7/sclo/x86_64/ &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/epel/6/x86_64/ /backup/yum/epel/6/x86_64 &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/6/extras/x86_64/ /backup/yum/centos/6/extras/x86_64 &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/6/updates/x86_64/ /backup/yum/centos/6/updates/x86_64 &&
rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/6/os/x86_64/ /backup/yum/centos/6/os/x86_64 &&
#rsync -avrt rsync://rsync.mirrors.ustc.edu.cn/centos/6/centosplus/x86_64/ /yum/centos/6/centosplus/x86_64
rsync -avrt rsync://mirrors.ustc.edu.cn/centos/6/sclo/x86_64/ /backup/yum/centos/6/sclo/x86_64/
rsync -avrt rsync://li.nux.ro/download/nux/dextop/el7/x86_64/ /backup/yum/centos/7/centosplus/x86_64
三，在系统下数据盘里面创建目录,目录最好使用lvm格式，可以动态扩容，根据
/backup/yum/centos/7
/backup/yum/centos/6
/backup/yum/epel/7/x86_64
/backup/yum/epel/6/x86_64
四，定时同步vim /etc/crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
# For details see man 4 crontabs
# Example of job definition:
# .---------------- minute (0 - 59)
# | .------------- hour (0 - 23)
# | | .---------- day of month (1 - 31)
# | | | .------- month (1 - 12) OR jan,feb,mar,apr ...
# | | | | .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# | | | | |
# * * * * * user-name command to be executed
* * * * 0 root /usr/bin/sh /backup/rsync.sh
