2025年linux安装yum命令在线安装（linux怎么用yum安装）

大家好，我是讯享网，很高兴认识大家。

更新源可以获取最新的软件信息，以更新您的系统

YUM(Yellow dog  Updater Modified): yum是Redhat系列系统基于RPM包构建的软件更新机制，可以自动解决 rpm 包之间的依赖关系，所有软件包由集中的yum软件仓库提供。其理念是使用一个中心仓库(repository)管理一部分甚至一个distribution的应用程序相互关系，根据计算出来的软件依赖关系进行相关的升级、安装、删除等操作，减少了Linux用户一直头痛的dependencies的问题。可以同时配置多个资源库(Repository)，简洁的配置文件(/etc/yum.conf)，自动解决增加或删除rpm包时遇到的依赖性问题,保持与RPM数据库的一致性。

yum的配置文件在  /etc/yum.repos.d/ 下面，必须以 .repo 结尾！

配置本地yum源

配置本地yum源是通过本地映射光盘挂载到系统中，然后将yum的配置文件中的 baseurl 指向挂载的目录即可。

首先在虚拟机的这个配置中，勾选使用iso映射文件，然后选中我们iso文件所在的位置即可。

在虚拟机系统中，我们的 iso 文件是 /dev/sr0 设备,系统会默认把我们的iso文件挂载到 /run/media/\(username/ 目录下。但是现在我们要将iso文件挂载到 /mnt/cdrom 下。如果mnt目录下没有cdrom，那么我们自己新建一个。<p style="outline: 0px;margin-bottom: 16px;font-size: 16px;color:

配置完保存退出，清除yum缓存，查看yum中的包有多少，这里可以看到有11056个，比本地yum源的四千多个多了不少！
