前言
这期呢主要说一说Linux中包软件管理相关命令,这一期的命令虽然只有两个。但 软件包的安装和卸载都是我们平常最常用的,需要熟练掌握。
rpm和yum 是CentOS 主要的包软件管理。
两个命令各有用处,①yum需要互联网,yum会去网上的yum源获取所需的软件包
② rpm 操作相对复杂,需要我们做得更多
rpm rpm包管理器
1、简介
rpm 命令包含了安装、卸载、升级、查询和验证5个基本功能
2、语法格式3、参数选项
参数参数说明-q查询软件包-p后面接“.rpm”为后缀的软件包-i①与-qp配合使用,表示显示软件包的概要信息 info
②安装软件包 install-l显示软件包种所有文件列表-R显示软件包依赖环境-v显示详细信息-h用“#” 显示安装进度条-a与-q参数搭配使用,用于查询所有的软件包-e卸载软件包-f查询文件或命令属于哪个软件包-U升级软件包4、 实践操作
我们下载一个rpm包telnet-server-0.17-66.el7.x86_64.rpm作为后续实践操作文件- [root@xiezhr test]# wget https://mirrors.aliyun.com/centos/7.9.2009/updates/x86_64/Packages/telnet-server-0.17-66.el7.x86_64.rpm
