yum工具的使用
yum仓库管理
1. yum本地仓库
挂载镜像
[root@lnh ~]# cd /etc/yum.repos.d/
[root@lnh yum.repos.d]# ls
CentOS-Stream-AppStream.repo CentOS-Stream-RealTime.repo
CentOS-Stream-BaseOS.repo epel-modular.repo
CentOS-Stream-Debuginfo.repo epel-playground.repo
CentOS-Stream-Extras.repo epel.repo
CentOS-Stream-HighAvailability.repo epel-testing-modular.repo
CentOS-Stream-Media.repo epel-testing.repo
CentOS-Stream-PowerTools.repo
[root@lnh yum.repos.d]# rm -rf *
[root@lnh yum.repos.d]# ls
[root@lnh yum.repos.d]#
//因为我们用的是centos8.5，所以有这些本地仓库，如果是redhat就没有，我们需要删除这些仓库然后进行创建
[root@lnh yum.repos.d]# vim xbz.repo
[root@lnh yum.repos.d]# ls
xbz.repo
[root@lnh yum.repos.d]# cat xbz.repo
[BaseOS]
name=111
baseurl=file:///mnt/BaseOS
gpgcheck=0
enabled=1
[AppStream]
name=222
baseurl=file:///mnt/AppStream
gpgcheck=0
enabled=1
//配置本地仓库 复制快捷键5yy p
[root@lnh yum.repos.d]# mount /dev/cdrom /mnt/
mount: /mnt: /dev/sr0 already mounted on /mnt.
//挂载镜像，此处我已经挂载了
[root@lnh yum.repos.d]# dnf clean all
13 files removed
//清空yum本地缓存，此处用yum也可以但是用dnf可以解决它的一些依赖关系更好一些
[root@lnh yum.repos.d]# dnf list all

2. yum网络仓库
官方的网络yum仓库在国外
我们可以使用国内的yum仓库：
阿里云yum仓库(https://developer.aliyun.com/mirror/)
epel源
(https://developer.aliyun.com/mirror/)
163yum仓库
(http://mirrors.163.com/)
清华大学yum仓库
(https://mirrors.tuna.tsinghua.edu.cn/)
[root@lnh yum.repos.d]# ls
xbz.repo
[root@lnh yum.repos.d]# rm -rf *
[root@lnh yum.repos.d]# ls
[root@lnh yum.repos.d]#
//因为本地仓库和网络仓库不可以共存所以我们先删除本地仓库
