以LINUX REDHAT6.3为例：
本机插入 REDHAT6.3系统ISO镜像CD1
1.配置yum本地安装源：
以root用户登录系统
mkdir /mnt/cdrom
mount -t iso9660 /dev/sr0 /mnt/cdrom
cd /etc/yum.repos.d
查看目录是否有.repo后缀文件，没有则创建一个.repo文件,文件名随意。
vi local.repo
[LOCAL]
name=local
baseurl=file:///mnt/cdrom
enable=1
gpgcheck=0
yum clean all
2.安装nmap,并测试172.24.40.5是否开放80端口
