配置本地yum库

        通过配置本地yum服务器，为本地的linux以及局域网中的linux操作系统安装软件。本文的服务配置环境为：redhat enterprise 5.10，软件来源：系统镜像文件(rhel-server-5.10-x86-64-dvd.iso)。本次实验均在VMware Workstation虚拟机中完成。

一、 服务端安装

首先查询一下服务端是否安装：
[root@localhost ~]# rpm -qa yum
yum-3.2.22-40.el5(本机已安装)如未安装则进行下面操作.
1．yum服务端应安装以下软件
yum-3.2.22-40.el5

createrepo-0.4.4-2.fc6.noarch.rpm

2．准备安装程序包

虚拟机-->设置-->CD/DVD-->使用ISO映像文件-->浏览-->找到镜像文件-->设备状态（已连接和启动时链接都要勾选）。

进目录查看一下（这是默认的挂载点）

[root@localhost ~]# cd /misc/cd
[root@localhost cd]# ls

配置yum文件

[root@localhost ~]# vim /etc/yum.repos.d/rhel-debuginfo.repo

[rhel-debuginfo]
name=Red Hat Enterprise Linux $releasever - $basearch - Debug
baseurl=file:///misc/cd/Server/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

保存退出

 yum list | wc -l      查看一下

2556

五、客户端测试
yum clean all  /*清除旧的缓存数据*/

安装httpd测试一下

[root@localhost ~]# yum install httpd

 配置yum库主要为了解决依赖关系这个麻烦事。
