shell脚本实现自动配置yum

大家都知道在RedHat中yum的好处，可以解决依赖关系，轻松的安装和卸载软件包。下面的脚本是我当初在初学shell脚本编程时写的第一个可以完成实际功能的简单脚本，和大家分享一下。

#!/bin/bash

#This program is used for helping you configure yum for your system.

trap 'echo;exit 0;' 2 15

echo "This program will configure yum automatically. "

read -p "Please input the CD path:" path

until [ -e "$path"/Server ]
do
read -p "Error CD path!Please retry:" path
done

{
rpm -ivh $path/Server/createrepo-0.4.11-3.el5.noarch.rpm

createrepo -g $path/Server/repodata/comps-rhel5-server-core.xml $path/Server

createrepo -g $path/VT/repodata/comps-rhel5-vt.xml $path/VT

createrepo -g $path/Cluster/repodata/comps-rhel5-cluster.xml $path/Cluster

createrepo -g $path/ClusterStorage/repodata/comps-rhel5-cluster-st.xml $path/ClusterStorage
}&>/dev/null
