1配置基于HTTP协议的yum源服务器
#mkdir /media/cdrom
#mount /dev/cdrom /media/cdrom
yum -y install httpd

直接挂载                                                   服务器                    mkdir /var/www/html/centos
umount /dev/cdrom                                            cp -r /media/cdrom/*  /var/www/html/centos
mkdir /var/www/html/centos
mount /dev/cdrom/ /var/www/html/centos

systemctl start httpd
systemctl enable httpd

3配置基于FTP协议的yum 源服务器
#mkdir /media/cdrom
#mount /dev/cdrom /media/cdrom
yum -y install vsftpd*

直接挂载                                               服务器    mkdir /var/ftp/centos  
umount /dev/cdrom                        cp -r /media/cdrom/* /var/ftp/centos
mkdir /var/ftp/centos
mount /dev/cdrom/ /var/ftp/centos

用户收集的其他软件包需要手工创建repodata数据文件和存放目录，工具createrepo(光盘已有）
mkdir /var/ftp/other   //将软件包服务进来
cd /var/ftp/other
createrepo -g /var/ftp/centos/repodata/repomd.xml ./    //以现有的repodata目录为样板
ls -lh repodata


客户机操作
cd /etc/yum.repos.d
mkdir backup
mv *.repo backup
vim /etc/yum.repos.d/centos.repo
cd
[ftp-media]
name=ftp-media
baseurl=ftp://192.168.30.24/centos  指定服务器的IP地址
