安装htpd并设置开机启动
3 yum -y install httpd
yum -y install httpd
4 systemctl enable --now httpd

5 系统光盘上传至服务器/data/isos目录

6 mkdir /var/www/html/centos/{7,8} -pv

7 mount /data/isos/CentOS-7-x86_64-DVD-2009.iso /var/www/html/centos/7

mount /data/isos/CentOS-8.4.2105-x86_64-dvd1.iso /var/www/html/centos/8
至此已搭建完成

测试一下
1 vim /etc/yum.repos.d/base.repo注释掉原来的源地址,
添加baseurl=http://10.0.0.153/centos/7/

yum clean all

yum -y install httpd
