一配置本地 YUM 源
--1.1 实验环境
RHEL6：虚拟机

--1.2 挂载光驱
[root@redhat6 yum.repos.d]# mount /dev/cdrom /mnt
mount: block device /dev/sr0 is write-protected, mounting read-only

  备注：将光盘 ISO 文件挂载到目录 /mnt

--1.3 创建本地目录，用来 copy 光盘包
[root@redhat6 local_repo]# mkdir -p /opt/rpm/local_repo

--1.4 copy RPM 包到指定目录
[root@redhat6 log]# cd /mnt/Packages/
[root@redhat6 Packages]# cp * /opt/rpm/local_repo

--1.5 安装 createrepo 包
[root@redhat6 local_repo]# rpm -ivh createrepo-0.9.8-4.el6.noarch.rpm
warning: createrepo-0.9.8-4.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
Preparing...                ########################################### [100%]
   1:createrepo             ########################################### [100%]
     
   备注：createrepo 包安装成功
  
 
--1.6 创建 repo 数据库
 

 [root@redhat6 local_repo]# createrepo -d /opt/rpm/local_repo
1944/2804 - MAKEDEV-3.24-6.el6.i686.rpm                                        
iso-8859-1 encoding on Ville Skytt?ville.skytta@iki.fi> - 2.8.2-2

2804/2804 - perl-Archive-Extract-0.38-119.el6_1.1.i686.rpm

  备注：这个步骤需要点时间。

  
--1.7 编写 /etc/yum.repos.d/local_repo.repo 文件

   文件 /etc/yum.repos.d/local_repo.repo   内容如下。

 [rhel-source]
name=Red Hat Enterprise Linux Local repo   ##仓库描述
baseurl=file:///opt/rpm/local_repo         ##软件仓库位置
enabled=1                                  ##是否启用
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release   ##签名秘钥

--1.8 测试
