1、准备linux ISO系统镜像文件 （例如：rhel-server-5.5-i386-dvd.iso）
2、linux虚拟机(centos 7 192.168.50.24 )，启动sshd服务 systemctl start httpd.service
3、放置rhel-server-5.5-i386-dvd.iso到虚拟机 /dir 中
4、在 /var/www/html 目录下创建文件夹 redhat5.5
5、运行命令 mount -o loop /dir/rhel-server-5.5-i386-dvd.iso /var/www/html/redhat5.5/
通过网页访问 http://192.168.50.24/redhat5.5/ 看查看到系统目录
客户端本地设置
在/etc/yum.repos.d/ 目录中 修改文件rhel-source.repo（不存在可直接添加）
添加内容
[rhel-source]
name=Red Hat Enterprise Linux $releasever - Source
baseurl=http://192.168.50.24/redhat5.5/Server
enabled=1
gpgcheck=1
gpgcheck=1
gpgkey=
运行命令： service yum-updatesd restart
