![SouthEast][]

# 由来 #

RPM软件包形式管理软件虽然方便, 但是需要手工解决软件包的依赖关系.  
有时安装一个软件需要首先安装几十上百个其他软件, 手工解决则过于复杂.  
YUM的出现就是为了解决这个问题的.

# 说明 #

YUM, Yellowdog Updater Modified.  
是一个RPM的前端程序, 主要作用就是 自动解决RPM的依赖关系.

# 特点 #

自动解决依赖关系  
可以对RPM进行分组, 以组为单位进行批量安装操作  
引入仓库的概念, 且支持多个仓库  
配置简单

# 仓库 #

##  说明 ##

repository, repo  
仓库 存放着大量的RPM软件包,  
当使用YUM安装一个RPM包时, 会自动在仓库中查找依赖软件并安装.

##  仓库类型 ##

本地的  
通过 FILE协议 方式访问  
网络的  
通过 HTTP、FTP、NFS协议 方式访问

##  配置文件 ##

位置: /etc/yum.repos.d  
格式  
\[仓库名称\]  
name = 仓库的描述信息  
baseurl = http://www.foo.org/yum/rpms  
enabled = 0或1, 该仓库是否启用, 默认为1  
gpgcheck = 0或1, 是否校验  
注意  
YUM配置文件必须以".repo"结尾  
一个配置文件可以配置多个仓库  
/etc/yum.repos.d 目录下可以存在多个配置文件  
示例 : /etc/yum.repos.d/CentOS-Base.repo

    # The mirror system uses the connecting IP address of the client and the

    # geographically close to the client.  You should use this for CentOS updates
    # unless you are manually picking other mirrors.
    #
    # If the mirrorlist= does not work for you, as a fall back you can try the
    # remarked out baseurl= line instead.

yum whatprovides filename : 查询包含指定文件的rpm软件

# 创建yum仓库 #

1) 将所有rpm文件拷贝到 仓库(某个目录)  
2) 安装 createrepo 软件(通过rpm命令)  
3) 运行 createrepo命令  
作用: 创建repodata目录, 存放索引文件  
createrepo -v /rpm-directory  
4) 注: 如果有分组信息, 则在运行命令时使用 "-g" 来指定分组文件  
createrepo -g /tmp/\*comps.xml/rpm-directory  
CentOS/RHEL的分组信息保存于光盘 repodata/目录下  
文件名以 "comps.xml"结尾的xml文件  
5) 使用  
本地 : FILE协议  
网路 : HTTP FTP NFS  
示例  
1) 查看 CentOS\_6.3 光盘中的 仓库Packages(所有rpm包)  
  
2) 创建本地仓库目录"/wuqinfei-yum-repo", 并将 Packages中的rpm包考进来  
3) 安装 createrepo软件
