CentOS建立本地yum源shell脚本

使用方法：
1.下载系统版本对应的”deltarpm-version.el6.x86_64.rpm python-deltarpm-version.el6.x86_64.rpm createrepo-version.noarch.rpm”,放到脚本对应的同级目录。
2.把需要做成源的rpm（建议把对应系统版本的32位和64位iso中的rpm都拿出来）放到一个目录下，如放到”/tmp/packages”,直接运行脚本即可。

代码如下，就不多说了

#!/bin/sh

#请下载系统版本对应的”deltarpm-version.el6.x86_64.rpm python-deltarpm-version.el6.x86_64.rpm
#createrepo-version.noarch.rpm”,放到脚本对应的同级目录
 
set -e

function CheckRoot()
{
#check if currect use is root user
CUR_USER=`whoami`
if [ $CUR_USER != ‘root’ ]
then
      echo ‘The operation will modify system files,you should be  root!’
　　exit 1
fi
}

function MkDir()
{
if [ ! -d $1 ]
then
　　mkdir $1 > /dev/null
fi
}

function RollBack()
{
ORIG_DIR=`pwd`
cd /etc/yum.repos.d > /dev/null
MkDir /ect/yum.repos.d/configYum_rb
mv *.repo configYum_rb/ > /dev/null
mv backup/*.repo . > /dev/null
rm -fr backup/ configYum_rb/ > /dev/null
yum clean all > /dev/null
yum makecache > /dev/null
yum repolist all
}

function Create()
{
echo ‘Begin to create local yum source … …’
ORIG_DIR=`pwd`

#backup currect config
if [ ! -d “/etc/yum.repos.d” ]
　　then
　　　　echo ‘/etc/yum.repos.d is not existed , please check your system!’
　　　　exit 1
　　fi

cd /etc/yum.repos.d > /dev/null
MkDir /etc/yum.repos.d/backup
mv ./*.repo backup/

#create local.repo
cat >> local.repo << EOF
[localrepo]
name=localrepo
baseurl=file://$1
gpgcheck=0
enabled=1
EOF

retrpm=`rpm -qa | grep deltarpm`
if [ -z “$retrpm” ]
then
　　rpm -ivh $ORIG_DIR/deltarpm-.*.rpm > /dev/null
　　rpm -ivh $ORIG_DIR/python-deltarpm-.*.rpm > /dev/null
fi

#check if createrepo if existed
which createrepo > /dev/null

if [ $? -eq 1 ]
then
　　rpm -ivh $ORIG_DIR/createrepo.*.noarch.rpm > /dev/null
　　if [ $? -ne 0 ]
　　then
　　　　echo ‘Install createrepo failed !’
　　　　exit 1
　　fi
fi

createrepo $1 > /dev/null

if [ $? -ne 0]
then
　　echo ‘create repo failed !’
　　exit 1
fi

yum clean all > /dev/null
yum makecache > /dev/null
yum repolist all
}

function Help()
{
cat <<EOF
There are 2 ways to call this script, for example:
1. To create a local Yum source: ./configYum.sh /tmp/packages
2. To rollback previous operation: ./configYum.sh b
EOF
}

function Main()
{
if [ $# -ne 1 ]
then
　　Help
elif [ -d $1 ]
then
　　CheckRoot
　　Create $*
elif [ $1 = ‘b’ ]
then
　　CheckRoot
　　RolllBack
else
　　Help
fi
}

Main $*
