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：

1、nginx.org官网下载nginx-1.19.9.tar.gz包

2、Nginx源码包解压


[root@superman-vm01 ~]# tar -xvf nginx-1.19.9.tar.gz

..........






3、源码Configure预编译，需进入解压后的目录执行./configure指令，分号“；”表示连接多个命令。


[root@superman-vm01 ~]# cd nginx-1.19.9/;./configure

make[1]: Leaving directory `/root/nginx-1.19.9'


[root@superman-vm01 nginx-1.19.9]#  

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：

YUM命令工具指南，YUM格式为：


YUM [command] [package] -y|-q 其中的[options]是可选。-y安装或者卸载出现YES时，自动确认yes；-q不显示安装的过程。


yum install sysstat         安装sysstat软件包；


yum reinstall sysstat                   重新安装sysstat软件包


yum search sysstat      YUM搜索软件包；


yum list sysstat            显示指定程序包安装情况sysstat；


yum list          显示所有已安装及可安装的软件包；


yum remove sysstat       删除程序包sysstat；


yum erase sysstat       删除程序包sysstat；


yum update          内核升级或者软件更新；


yum update sysstat       更新sysstat软件；


yum check-update       检查可更新的程序；


yum info sysstat            显示安装包信息sysstat；


yum provides        列出软件包提供哪些文件；


yum provides "*/rz"      列出rz命令由哪个软件包提供；


yum grouplist            询可以用groupinstall安装的组名称；


yum groupinstall "Chinese Support"   安装中文支持；


yum groupremove "Chinese Support"    删除程序组Chinese Support；


yum deplist sysstat      查看程序sysstat依赖情况；


yum clean   packages      清除缓存目录下的软件包；


yum clean   headers      清除缓存目录下的headers；


yum clean   all            清除缓存目录下的软件包及旧的headers。


yum repolist {all|enabled|disabled}     列出所有/已启用/已禁用的yum源


yum list {all|installed|avaliable}      列出所有/已安装/可安装的软件包

5. 同步外网源

在企业实际应用场景中，仅仅靠光盘里面的RPM软件包是不能满足需要，我们可以把外网的YUM源中的所有软件包同步至本地，可以完善本地YUM源的软件包数量及完整性。

5.1 安装reposync工具

[root@superman-vm01 ~]# yum install yum-utils createrepo -y


Loaded plugins: fastestmirror, langpacks

# 创建本地目录:


[root@superman-vm01 ~]# mkdir /data/{centos,epel}


[root@superman-vm01 ~]# 






# 同步yum源：


[root@superman-vm01 ~]# reposync -r base -r updates -p /data/centos/

# 生成元数据：


[root@superman-vm01 ~]# createrepo /data/centos


[root@superman-vm01 ~]# 






# 结合前面所学制作本地源，如果想让其它服务器使用该源，后面可以结合nginx发布。
