配置yum源并安装dhcp脚本

执行前提是：
关闭防火墙和selinux
配置好本机IP
配置本地原iso镜像文件
vim /etc/fstab写入：
/dev/cdrom /mnt/cdrom iso9660 defaults loop 0 0

以下是脚本内容：
#!/bin/sh
echo "
　　1. install dhcp
　　2. configer dhcp
　　"

echo "Please input you choice:"
read shu

if [ $shu -eq 1 ]; then
　　mkdir /mnt/cdrom
　　rm -rf /etc/yum.repos.d/*
　　cd /etc/yum.repos.d

touch my.repo
echo "[my_repo]" > /etc/yum.repos.d/my.repo
echo "name=my local repo" >> /etc/yum.repos.d/my.repo
echo "baseurl=file:///mnt/cdrom" >> /etc/yum.repos.d/my.repo
echo "enabled=1" >> /etc/yum.repos.d/my.repo
echo "gpgchech=0" >> /etc/yum.repos.d/my.repo

mount /dev/cdrom /mnt/cdrom -o loop
yum install dhcp -y

elif [ $shu -eq 2 ];then
　　echo "please input your subnet:"
read subnet
echo "please input you netmask"
read netmask
echo "subnet $subnet netmask $netmask" >> /etc/dhcp/dhcpd.conf
echo "{" >> /etc/dhcp/dchpd.conf

echo "please input you ip range:"
read range
echo " range $range" >> /etc/dhcp/dhcpd/conf

echo "pkease input your option routers:"
read routers
echo " option routers $routers;" >> /etc/dhcp/dhcpd.conf

echo "default-lease-time:"
read xianzhi
echo "default-lease-time $xianzhi;" >> /etc/dhcp/dhcpd.conf
else
exit
fi
