RPM简介

RPM的全名是Red Hat Package Manager，本意是Red Hat 软件包管理，顾名思义是Red Hat 贡献出来的软件包管理。

简单说，RPM就是将部署统一化，一键化。

RPM优点和缺点

1. 优点
   
   由于已经编译完成并且打包，所以安装很方便
   
   由于套件信息已经记录在Linux主机的数据库中，方便查询、升级与卸载
2. 缺点
   
   安装环境必须与打包时的环境一致
   
   需要满足软件的依赖属性需求
   
   卸载时需要特别小心，最底层的软件不可以先删除，否则可能造成整个系统出问题

RPM 常用命令

rpm 基本命令

安装： rpm -ivh cloud-eyes-0.0.1-96e3ea5.noarch.rpm

升级： rpm -Uvh cloud-eyes-0.0.1-96e3ea5.noarch.rpm

查询已安装的rpm： rpm -qa cloud-eyes

查询某rpm详细信息：rpm -qpi cloud-eyes-0.0.1-094a474.noarch.rpm

卸载： sudo rpm -e cloud-eyes –allmatches –nodeps （强制卸载）
