1、总结rpm和yum实现程序包的管理功能.
RPM
RPM解释：
RPM全称为RedhatPackageManager，最早由RedHat公司制定实施，随后被GNU开源操作系统接受并成为很多Linux系统(RHEL)的既定软件标准.
RPM的特点就是将你要安装的软件先编译过，并且打包成RPM机制的安装包。
优点：（1）已经编译好了，所以软件安装方便。
（2）在被安装，会先检查系统的硬盘容量，操作系统版本等，避免文件被错误安装。
（3）rpm本身提供软件版本信息，依赖属性软件名称，软件用途说明，软件所含文件等信息。
程序包的组成部分：
二进制程序：/bin, /sbin,/ /usr/bin, /usr/sbin,
库文件：/lib64, /usr/lib64
配置文件：/etc
帮助文件：manual, info,
命名规则：
以 zsh-4.3.11-4.el6.centos.x86_64.rpm来说明:
zsh：是软件的名字
4.3.11-4：这是软件的版本号
e16：基于该版本的软件包的发行版本号，有软件打包商设置，不一定是原始软件开发商.
x86_64:编译的软件包可以运行的处理器架构（x86_64）
特殊说明：
1、fcXX，elXX：表示这个软件包的发行商版本，就像这里的fc18，说明这个软件包是在Fedora 18下使用的。而openssl-1.0.0-20.el6.x86_64.rpm表示这个软件包是在RHEL 6.x(Red Hat Enterprise Linux)/CentOS 6.x下使用。
2、devel：表示这个RPM包是软件的开发包，例如mysql-devel-5.1.52-1.el6_0.1.i686.rpm。
3、noarch：说明这样的软件包可以在任何平台上安装，不需要特定的硬件平台。在任何硬件平台上都可以运行。
安装，卸载类：
-i：install的意思。
-v:更详细的安装信息画面
-h：显示安装进度
--nodeps：忽略依赖关系
--replacepkgs 重装软件包
-e：卸载软件包
1.安装rpm -ivh zsh-4.3.11-4.el6.centos.x86_64.rpm 安装软件包:
2安装rpm -ivh qt3-MySQL-3.3.8b-30.el6.x86_64.rpm 出现依赖包错误显示：
如果要强制安装此rpm包就需要 --nodeps 参数：
4.如果一个软件已经安装过但是想要重装的话就需要--replacepkgs
5.如果要卸载一个软件：rpm -e
查询类：
-q：仅查询，后面的软件名称是否安装。
-qa：列出系统上已经安装的所有软件名称。
-ql：列出该软件所有的文件与目录所在的完整文件名。
-qi：列出软件的详细信息，包含开发商版本说明。
-qf：查询软件由那个包生成的。
-qc：查看当前程序生成了哪些配置文件。
-p: 查询针对是未安装的程序包文件
1.查询软件包是否安装：rpm -q name：
2.查询已安装的软件：rpm -qa（我这里一共安装了454个软件)
3.查询zsh所有的文件目录：rpm -ql
4.查询zsh包含有的信息：rpm -qi
5.查询软件由哪个包生成的：rpm -qf
6.查询当前软件生成了哪些配置文件：rpm -qc
7.查询针对未安装的程序文件：rpm -qpi ，rpm -qpl
软件更新：
-Uvh：后面跟的软件如果没有安装过，则直接安装，如果有安装旧版，则系统自动更新。
-Fvh：后面跟的软件如果没有安装过，则不会安装，只有安装到系统内部的软件会被升级。
校验：
rpm {-V|--verify} [select-options] [verify-options]
S file Size differs
M Mode differs (includes permissions and file type)
5 digest (formerly MD5 sum) differs
D Device major/minor number mismatch
L readLink(2) path mismatch
U User ownership differs
G Group ownership differs
T mTime differs
P caPabilities differ
实例：修改一个程序文件然后在校验：rpm -V zsh
[[email protected] Packages]# rpm -V zsh S.5....T. /usr/share/zsh/4.3.11/functions/zrecompile [[email protected] Packages]#
包校验：
来源合法性验正：非对称加密
完整性验正：单向加密
导入密钥：rpm -ivh RPM-GPG-KEY-CentOS-6
校验：rpm -K /PATH/TO/RPM_FILE
[[email protected] Packages]# rpm -K zsh-4.3.11-4.el6.centos.x86_64.rpm zsh-4.3.11-4.el6.centos.x86_64.rpm: rsa sha1 (md5) pgp md5 OK
YUM
YUM命令的解释：
yum（全称为 Yellow dog Updater, Modified）是一个在Fedora和RedHat以及SUSE中的Shell前端软件包管理器。基於RPM包管理，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软体包，无须繁琐地一次次下载、安装。yum提供了查找、安装、删除某一个、一组甚至全部软件包的命令，而且命令简洁而又好记。
yum程序的配置文件：
/etc/yum.conf
定义全局配置：对所有仓库都适用的配置
/etc/yum.repos.d/*.repo
一个文件通常用于一个或一组功能相近或相关的仓库
定义一个仓库指向：
[REPO_ID]
name=
baseurl=
# mirrorlist=SCHEME://HOSTNAME/PATH/TO/MIRROR_LIST_FILE
enabled={1|0}
gpgcheck={1|0}
gpgkey=
cost=
比如创建阿里源和epel源：
[centos] name=Centos aliyun baseurl=http://mirrors.aliyun.com/centos/6/os/x86_64/ enabled=1 gpgcheck=0 [Fedora-epel] name=Fedora-epel baseurl=http://mirrors.aliyun.com/epel/6Server/x86_64/ enabled=1 gpgcheck=0
