自定义Yum仓库
 问题

1. 准备软件包目录
2. 新建文件夹 /custom
3. 拷入 linuxqq、realplayer 两个 RPM 包
4. 为软件包目录生成 repodata/ 数据
5. 从 RHEL 6 光盘安装 createrepo
6. 执行 createrepo /custom
7. 测试上述 YUM 源
    方案
   本题的思路：
   1）先搭建好yum仓库，安装createrepo软件包
   2）创建目录“/custom”
   3）将事先准备好的rpm包，复制到目录“/custom”目录里
   4）执行 createrepo /custom
   5）编写新的yum客户端配置文件，添加新的yum源
    步骤
   实现此案例需要按照如下步骤进行。
   步骤一：准备软件包目录
   新建文件夹 /custom，命令操作如下所示：
   [root@localhost /]# mkdir /custom
   [root@localhost /]# ls -ld /custom/
   drwxr-xr-x. 2 root root 4096 1月 13 21:27 /custom/
   [root@localhost /]# ls /root/桌面/
   httpd-2.2.25.tar.gz linuxqq-v1.0.2-beta1.i386.rpm RealPlayer11GOLD.rpm
   [root@localhost /]#
   拷入 linuxqq、realplayer 两个 RPM 包
   [root@localhost /]# cp /root/桌面/linuxqq-v1.0.2-beta1.i386.rpm /custom/
   [root@localhost /]# cp /root/桌面/RealPlayer11GOLD.rpm /custom/
   [root@localhost /]# ls /custom/
   linuxqq-v1.0.2-beta1.i386.rpm RealPlayer11GOLD.rpm
   [root@localhost /]#
   步骤二：为软件包目录生成 repodata/ 数据
   从 RHEL 6光盘安装 createrepo。（因cretaerepo包依赖关系复杂首先要搭建yum）
   命令操作如下所示：
   [root@localhost /]# umount /dev/cdrom
   [root@localhost /]# mount /dev/cdrom /media/ //挂载光盘设备到/media
   mount: block device /dev/sr0 is write-protected, mounting read-only
   [root@localhost /]# mount | tail -1
   /dev/sr0 on /media type iso9660 (ro)
   [root@localhost /]# vim /etc/yum.repos.d/rhel6.repo //配置客户端文件
   [rhel-6]
   name=Red Hat Enterprise Linux 6
   baseurl=file:///media/
   enabled=1
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
   [root@localhost /]# yum repolist //客户端测试yum

   repo id repo name status
   rhel-6 Red Hat Enterprise Linux 6 3,690
   repolist: 3,690
   [root@localhost /]# yum -y install createrepo //利用yum安装createrepo
   执行 createrepo /custom
   [root@localhost /]# ls /custom/
   linuxqq-v1.0.2-beta1.i386.rpm RealPlayer11GOLD.rpm
   [root@localhost /]# createrepo /custom/

[root@localhost /]# ls /custom/
linuxqq-v1.0.2-beta1.i386.rpm RealPlayer11GOLD.rpm repodata
[root@localhost /]#
步骤三：测试上述 YUM 源
编写客户端配置文件，命令操作如下所示：
[root@localhost /]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
rhel6.repo rhel-source.repo
[root@localhost yum.repos.d]# cp rhel6.repo myrpm.repo
[root@localhost yum.repos.d]# vim myrpm.repo
[rhel-myrpm]
name=Red Hat Enterprise Linux myrpm
baseurl=file:///custom
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
测试yum源
[root@localhost /]# yum repolist
