之前使用的yum仓库，是直接将baseurl设置为官方镜像，或者是安装光盘。本节内容将介绍如何将互联网上下载到本地的rpm包制作成本地的yum源。定制yum源的命令是 createrepo：
[root@localhost ~]# createrepo
-bash: createrepo: command not found # 该命令尚未安装，可以使用yum安装
[root@localhost ~]# yum -y install createrepo

一、 制作本地的yum源
现在到官方站点上下载几个rpm包到本地（可以使用ftp工具FileZilla将本机上下载的文件传输到虚拟机中）：
[root@localhost ~]# ls
anaconda-ks.cfg if_exist.sh Templates axis-1.2.1-7.5.el6_5.noarch.rpm install.log Videos axis-javadoc-1.2.1-7.5.el6_5.noarch.rpm install.log.syslog xen-4.4.1-5.el6.x86_64.rpm axis-manual-1.2.1-7.5.el6_5.noarch.rpm mkscript zsh-4.3.10-7.el6.x86_64.rpm Desktop Music zsh-html-4.3.10-7.el6.x86_64.rpm Documents Pictures Downloads Public # 下载了很多rpm包

[root@localhost ~]# createrepo /yum/package/

[root@localhost ~]# ls /yum/package/

[root@localhost ~]# cd /yum//package/repodata/
[root@localhost repodata]# ls
# repodata中有很多新生成的文件 4aa67d3d6de3fb964dd96bc15e3849a95c0c26add8bdf871b584c42fafc6564d-other.sqlite.bz2 # 这是个小型的嵌入式数据库引擎 9501c262742c6024ec0bf8e0e0a876c1ab8c51c3c9f9e8b54205c03121c2274f-primary.xml.gz af1104a240755c3d4cf5d8ead181afed54f3395d71f6eec76210bae9aeac6b5f-primary.sqlite.bz2 # 主配置文件，包含当前仓库内的所有rpm包，以及各rpm包之间的依赖关系 d8d9144e02ffe32302d157984b9fb84246e30e78a3ab440c32b74e73489de44e-filelists.sqlite.bz2 f501ede79b66c9f96117d7070cffae3c8aa621723f13f53999cd2a91b621cf1e-filelists.xml.gz # 当前目录中所有rpm包的文件列表 repomd.xml # 核心文件，用来保留下面六个文件的时间戳信息，当升级rpm包时，yum会将本地rpm包的缓存时间戳和该文件中的时间戳进行比较，如果一致，说明远程服务器的rpm包没有更新 （本地的缓存时间戳保存在/var/cache/yum） 832dc759e3507b97d6b92ce2d82aee1242d2b15839b0788ab7ec342fe059079f-other.xml.gz # 其他信息，如rpm包的改变日志等（每次rpm包升级的变化），rpm -q --changelog会依赖这个文件
[root@localhost repodata]# rpm -q --changelog bash
* Tue Jul 09 2013 Roman Rakus <rrakus@redhat.com> - 4.1.2-15 - Fixed a bug that caused trap handlers to be executed recursively, corrupting internal data structures.

[root@localhost repodata]# vim /etc/yum.repos.d/localrepo.repo

[root@localhost ~]# yum repolist
