centos5 本地配置YUM源

目錄 /data/Centos/i386/

一、掛載文件
mkdir -p /mnt/soft
mount -o loop -t iso9660 /dev/cdrom /mnt/soft
cd /data/Centos/i386/

2.新建一個自定義的目錄，用來放置你的RPM包，並複製一份。
mkdir -p /data/Centos/i386/
cp -rf /mnt/soft/CentOS/ /data/CentOS/i386/
 
3.將/mnt/soft下的repodata/ 拷貝到/data/Centos/i386/CentOS下
cp -rf /mnt/soft/repodata/ /data/Centos/i386/CentOS/   
 
4.安裝rpm -ivh /mnt/soft/CentOS/createrepo-0.4.11-3.el5.noarch.rpm  （此包是用來安裝服務端設置軟件倉庫及信息文件）

5.生成客戶端所需的信息文件
createrepo -g /mnt/soft/repodata/comps.xml /data/Centos/i386/
 
6.將key文件（用於客戶端與服務端的認證）拷入指定目錄/data/Centos/i386 下
cp /mnt/soft/RPM-GPG-KEY-CentOS-5 /data/Centos/i386/

7.更改yum的配置文件，更改以前CentOS-Base.repo要作好備份
vim CentOS-Base.repo
[base]
name=CentOS5.7-base
baseurl=file:///data/Centos/i386/
enable=1
gpgcheck=1
gpgkey=file:///data/Centos/i386/RPM-GPG-KEY-CentOS-5

先執行下yum clean all
 
驗證結果
