一、手动配置使用dvd作为yum源

1、mkdir /media/cdrom                                             #创建挂载点

2、mount /dev/cdrom /media/cdrom                         #挂载光盘

3、rpm -qa |grep yum                                                #查看有没有yum

4、mkdir /var/yum                                                       #创建yum目录用于存放rpm包

5、cp -r /media/cdrom/* /var/yum                             #拷贝光盘里的rpm包到/var/yum目录里面

6、rpm -q createrepo                                                #查看createrepo包有没有安装

7、rpm -ivh /media/cdrom/Server/createrepo-*     #如果没有按照安装这个包

8、创建yum repository的xml-rpm-metadata

createrepo  -g  /var/yum/Server/repodata/comps-rhel5-server-core.xml  /var/yum/Server/

createrepo  -g  /var/yum/VT/repodata/comps-rhel5-vt.xml  /var/yum/VT/

createrepo  -g  /var/yum/Cluster/repodata/comps-rhel5-cluster.xml  /var/yum/Cluster/

createrepo -g  /var/yum/ClusterStorage/repodata/comps-rhel5-cluster-st.xml  /var/yum/ClusterStorage/

9、vi /etc/yum.repos.d/local.repo                     # 创建本地yum客户端的repo文件,名字可以随便起，但是要以.repo为后缀

[server]                                                              #yum块区域

name=Server                                                     # 名字可以随便起

baseurl=file:///var/yum/Server                            #搜索路径，必须指向你本机的yum源路径

gpgcheck=0         #gpgcheck是gpg验证是否开启的选项，1是开启，0是不开启，一般情况可以关掉

enabled=1              #是否启用，0为不启用，1为启用，涂过没这一项，就是启用

[VT]

name=VT

baseurl=file:///var/yum/VT

gpgcheck=0

[Cluster]

name= Cluster

baseurl=file:///var/yum/ Cluster

gpgcheck=0

[CS]

name= ClusterStorage

baseurl=file:///var/yum/ ClusterStorage

gpgcheck=0

二、用脚本自动实现yum配置

#!/bin/bash

if [ -e /media/cdrom ];then

mount /dev/cdrom /media/cdrom

else

mkdir /media/cdrom

mount /dev/cdrom /media/cdrom

fi

if [ -e /var/yum ];then

echo "coping to file from CDROM" && cp -r /media/cdrom/* /var/yum &

else

mkdir /var/yum && echo "coping to file" && cp -r /media/cdrom/* /var/yum &

fi

rpm -qa |grep yum &>/dev/null

if  [ $? -eq 0 ];then

rpm -q createrepo

if [ $? -ne 0 ];then

rpm -ivh /media/cdrom/Server/createrepo*

fi

fi

creatxml() {

createrepo -g /var/yum/Server/repodata/comps-rhel5-server-core.xml /var/yum/Server

createrepo -g /var/yum/VT/repodata/comps-rhel5-vt.xm /var/yum/VT

createrepo -g /var/yum/Cluster/repodata/comps-rhel5-cluster.xml /var/yum/Cluster

createrepo -g /var/yum/ClusterStorage/repodata/comps-rhel5-cluster-st.xml /var/yum/ClusterStorage

}

creatxml   #对函数引用

cat >> /etc/yum.repos.d/local.repo << eof

[server]

name=server

baseurl=file:///var/yum/Server

gpgcheck=0

enable=1

[VT]

name=vt

baseurl=file:///var/yum/VT

gpgcheck=0

enable=1

[Cluster]

name=cluster

baseurl=file:///var/yum/Cluster

gpgcheck=0

enable=1

[ClusterStorage]

name=cluster

baseurl=file:///var/yum/ClusterStorage

gpgcheck=0

enable=1
