场景：在CentOS 7.9操作系统上，使用rpm命令安装、卸载、查看软件包。

版本：

操作系统：CentOS 7.9

名词：

RPM：Red-Hat Package Manager的简称。一个命令行驱动的软件包管理工具，用来安装、卸载、校验、查询和更新Linux系统上的软件包。它生成具有.rpm扩展名的文件。

命名规则：rpm包命名规则一般包括名称、版本、架构、和.rpm后缀。

1.rpm常用命令

(1)帮助命令

命令：rpm --help

功能：查看rpm 支持全部命令和选项，在实际工作中，查看这个手册应该是必备之选。

(2)安装rpm包

安装指定包：rpm -ivh yum-utils-1.1.31-54.el7_8.noarch.rpm

安装指定包：rpm -ivh --nodeps yum-utils-1.1.31-54.el7_8.noarch.rpm

安装指定包：rpm -ivh --force yum-utils-1.1.31-54.el7_8.noarch.rpm

安装目录下全部包：rpm -ivh ./*

功能：安装指定软件包，-i是install安装；-v是打印详细日志；-h是在安装包时打印哈希标记，显示安装进度；--nodeps不校验依赖包；--force强制安装。

(3)卸载rpm包

卸载包命令：rpm -e yum-utils-1.1.31-54.el7_8

卸载包命令：rpm -e --nodeps yum-utils-1.1.31-54.el7_8

功能：卸载rpm包，-e是erase简写，就是清除卸载包；--nodeps，是代表不确认包的依赖。

(4)查看已安装的包

查询已安装的rpm包列表：rpm -qa

已安装包中的查询包含关键字的包：rpm -qa | grep yum-utils

(5)查看已安装包的信息

命令：rpm -qi yum-utils

功能：查看指定的已安装包的详细信息。比如包名称、版本、发行版本、架构、许可证、构建日期等。一般字段包括：Name、Version、Release、Architecture、InstallDate、Group、Size、License、Signature、SourceRPM、BuildDate、BuildHost、Relocations、Packager、Vendor、URL、Summary、Description。

(6)查看已安装包的文件

命令：rpm -ql yum-utils

功能：查看安装包的文件列表。

2.rpm命令和选项

命令：rpm --help

功能：查看rpm 支持全部命令和选项，在实际工作中，查看这个手册应该是必备之选。
