源码包

源码包概述：

源码包的优缺点

二进制包-二进制包分类

不同Linux版本，二进制包格式不相同

RPM包优缺点

RPM安装时的依赖性— 致命缺点

RPM包的安装

rpm包的命名规则

Rpm手工安装

对于rpm依赖关系的解决办法

以上解决办法在实际操作中还是很繁琐，所以一般使用以下办法

rpm包安装时安装路径

RPM命令

RPM包升级命令

RPM包卸载命令

（一般卸载使用此命令而不使用yum的卸载命令，因为有可能产生文件垃圾）

yum安装–RPM包在线安装

Yum源配置文件解析

文件/etc/yum.repos.d

文件CentOS-Base.repo–更改yum源的文件
