第一步
搭建本地yum源仓库（需确保本地镜像成功挂载）
rm -rf /etc/yum.repos.d/*
vim /etc/yum.repos.d/centos.repo
[centos]
name=centos
baseurl=file:///opt/centos
enabled=1
gpgcheck=0
mkdir /opt/centos
mount /etc/cdrom /mnt
cp -rvf /mnt/* /opt/centos
umout /mnt
yum makecache #生成本地源缓存
第二步 配置http源
yum -y install httpd
yum -y install createrepo* #下载索引
mkdir /var/www/html/centos
cd /var/www/html && chmod 777 -R centos
vim /etc/yum.repos.d/lan.repo
[lan]
name=lan
baseurl=http://本机ip/centos
enabled=1
gpgcheck=0
#建立索引
cd /var/www/html/centos
createrepo centos
#关闭防火墙和SELINUX
systemctl stop firewalld
systemctl disable firewalld
vim /etc/selinux/config
SELINUX=Disabled
测试：
使用浏览器访问 http://本机ip/centos/centos/Packages
出现以上界面，即为成功。
