众所周知
在linux上在线安装软件需要用到yum命令经常下述命令来安装 yum install [-y] 包名 #-y的意思就是确认安装如果不添加-y则后续还需要再确认一下 但是实际安装的时候经常遇到下述问题
报错没有可用的包 此时引出了一个概念
yum源是什么
Yum源是指Yum软件包管理器在系统中使用的软件源。Yum全称为Yellowdog Updater, Modified是一款在Linux系统中常用的软件包管理器用于自动化地下载、安装、更新和删除软件包。Yum源可以理解为存储软件包的仓库用户可以通过Yum源获取和安装所需的软件包。Yum源包含了各种软件包的元数据信息可以根据用户的需求搜索、安装和更新软件包。通过配置不同的Yum源用户可以访问不同的软件仓库以满足不同的需求。
所以对于日常用户来说要做的就是修改yum源的配置文件
配置yum源
编辑yum源文件只要是在/etc/yum.repos.d/路径下的.repo的文件都可以名字可以随便起。例如当前的文件命名为aliyun.repo vi /etc/yum/repos.d/aliyum.repo 输入以下内容注意这个示例是centos操作系统的yum源其他操作系统不能直接复制
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist does not work for you, as a fall back you can try the
# remarked out baseurl line instead.
