本文主要是介绍Linux云计算-05_Linux软件包管理，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！
本章介绍Linux系统软件的安装、卸载、配置、维护以及如何构建企业本地YUM光盘源及HTTP本地源。
1 RPM软件包管理
Linux软件包管理大致可分为二进制包、源码包，使用的工具也各不相同。Linux常见软件包分为两种，分别是源代码包（Source Code）、二进制包（Binary Code），源代码包是没有经过编译的包，需要经过GCC、C++编译器环境编译才能运行，二进制包无需编译，可以直接安装使用。
通常而言，可以通过后缀简单区别源码包和二进制包，例如.tar.gz、.zip、.rar结尾的包通常称之为源码包，以.rpm结尾的软件包称之为二进制包。真正区分是否为源码还是二进制还得基于代码里面的文件来判断，例如包含.h、.c、.cpp、.cc等结尾的源码文件，称之为源码包，而代码里面存在bin目录可以执行文件，称之为二进制包。
CentOS操作系统中有一款默认软件管理的工具，红帽包管理工具（Red Hat Package Manager，RPM）。
使用RPM工具可以对软件包实现快速安装、管理及维护。RPM管理工具适用的操作系统包括：CentOS，RedHat，Fedora，SUSE等，RPM工具常用于管理.rpm后缀结尾的软件包。
RPM软件包命令规则详解如下：
RPM包命名格式为： name-version.rpm name-version-noarch.rpm name-version-arch.src.rpm 如下软件包格式： epel-release-6-8.noarch.rpm perl-Pod-Plainer-1.03-1.el6.noarch.rpm 以yasm-1.2.0-4.el7.x86_64.rpm为列解析如下： RPM包格式解析如下： name 软件名称，例如yasm、perl-pod-Plainer； version 版本号，1.2.0通用格式：“主版本号.次版本号.修正号”； 4表示是发布版本号，该RPM包是第几次编译生成的； arch 适用的硬件平台，RPM支持的平台有：i386、i586、i686、x86_64、sparc、alpha等。 .rpm 后缀包表示编译好的二进制包，可用rpm命令直接安装； .src.rpm 源代码包，源码编译生成.rpm格式的RPM包方可使用； el* 软件包发行版本，el6表示该软件包适用于RHEL 6.x/CentOS 6.x； devel： 开发包； noarch： 软件包可以在任何平台上安装。
RPM工具命令详解如下：
RPM 选项 PACKAGE_NAME -a, --all 查询所有已安装软件包； -q，--query 表示询问用户，输出信息； -l, --list 打印软件包的列表； -f, --file FILE查询包含FILE的软件包； -i, --info 显示软件包信息，包括名称，版本，描述； -v, --verbose 打印输出详细信息； -U, --upgrade 升级RPM软件包； -h,--hash 软件安装，可以打印安装进度条； --last 列出软件包时，以安装时间排序，最新的在上面； -e, --erase 卸载rpm软件包 --force 表示强制，强制安装或者卸载； --nodeps RPM包不依赖 -l, --list 列出软件包中的文件； --provides 列出软件包提供的特性； -R, --requires 列出软件包依赖的其它软件包； --scripts 列出软件包自定义的小程序。

3 源码包软件安装
通常使用RPM工具管理.rpm结尾的二进制包，而标准的.zip、tar结尾的源代码包则不能使用RPM工具去安装、卸载及升级，源码包安装有三个步骤，如下：
./configure 预编译，主要用于检测系统基准环境库是否满足，生成MakeFile文件； make 编译，基于第一步生成的makefile文件，进行源代码的编译； make install 安装，编译完毕之后，将相关的可运行文件安装至系统中； 使用make编译时，Linux操作系统必须有GCC编译器，用于编译源码。
源码包安装通常需要./configure、make、make install三个步骤，某些特殊源码可以只有三步中的其中一个步骤，或者两个步骤。
3.1 源码安装实战
以CentOS 7 Linux系统为基准，在其上安装Nginx源码包，企业中源码安装的详细步骤如下：

通过以上五个步骤，源码包软件安装成功，源码包在编译及安装时，可能会遇到各种错误，需要把错误解决之后，然后再进行下一步安装即可，后面章节会重点针对企业使用的软件进行案例演练。
4 YUM软件包管理
前端软件包管理器（Yellow Updater Modified，YUM）适用于CentOS、Fedora、RedHat及SUSE中的Shell命令行，主要用于管理RPM包，于RPM工具使用范围类似，YUM工具能够从指定的服务器自动下载RPM包并且安装，还可以自动处理依赖性关系。
使用RPM工具管理和安装软件时，会发现rpm包有依赖，需要逐个手动下载安装，而YUM工具的最大便利就是可以自动安装所有依赖的软件包，从而提升效率，节省时间。
4.1 YUM工作原理
学习YUM，一定要理解YUM工作原理，YUM正常运行，需要依赖两个部分，一是YUM源端，二是YUM客户端，也即用户使用端。
YUM客户端安装的所有RPM包都是来自YUM服务端，YUM源端通过HTTP或者FTP服务器发布。而YUM客户端能够从YUM源端下载依赖的RPM包是由于在YUM源端生成了RPM包的基准信息，包括RPM包版本号、配置文件、二进制信息、依赖关系等。
YUM客户端需要安装软件或者搜索软件，会查找/etc/yum.repos.d下以.repo结尾文件，CentOS Linux默认的.repo文件名为CentOS-Base.repo，该文件中配置了YUM源端的镜像地址，所以每次安装、升级RPM包，YUM客户端均会查找.repo文件。
YUM客户端如果配置了CentOS官方repo源，客户端操作系统必须能联外网，满足网络条件，才能下载软件并安装，如果没有网络，也可以构建光盘源或者内部YUM源。在只要YUM客户端时，YUM客户端安装软件，默认会把YUM源地址、Header信息、软件包、数据库信息、缓存文件存储在/var/cache/yum中，每次使用YUM工具，YUM优先通过Cache查找相关软件包，Cache中不存在，然后在访问外网YUM源。
4.2 YUM参数详解
由于YUM工具的使用简便、快捷、高效，在企业中得到广泛的使用，得到众多IT运维、程序人员的青睐，要能熟练使用YUM工具，需要先掌握YUM命令行参数的使用，如下为YUM命令工具的参数详解及实战步骤：

4.2.1 YUM安装实战
1、基于CentOS 7 Linux，执行命令yum install sysstat -y，安装sysstat服务
[root@superman-vm01 ~]# yum install sysstat -y Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.cn99.com * updates: mirrors.cn99.com Resolving Dependencies --> Running transaction check ---> Package sysstat.x86_64 0:10.1.5-17.el7 will be updated ---> Package sysstat.x86_64 0:10.1.5-19.el7 will be an update --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Updating: sysstat x86_64 10.1.5-19.el7 base 315 k Transaction Summary ================================================================================ Upgrade 1 Package Total size: 315 k Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Warning: RPMDB altered outside of yum.
