redhat8.4 本地源配置(redhat-local.repo)
一、配置软件仓库（软件仓库位置：/media/redhat）
1、建立目录 “redhat” 。
(建立目录命令：mkdir -p /media/redhat)
2、挂载光盘“rhel-8.4-x86_64-dvd.iso”。
3、将光盘文件夹“AppStream”、“BaseOS” 复制到 “/media/redhat”目录。
(复制文件夹命令：cp -r AppStream/ BaseOS/ /media/redhat )
二、配置软件仓库文件（/etc/yum.repos.d/）
1、查看本地源配置文件：
[root@redhatos ~]# cat /etc/yum.repos.d/redhat-local.repo
# redhat-local.repo
#
# You can use this repo to install items directly off the installation media.
# Verify your mount point matches one of the below file:// paths.
[local-baseos]
name=Redhat - local - BaseOS
baseurl=file:///media/redhat/BaseOS
file:///media/cdrom/BaseOS
file:///media/cdrecorder/BaseOS
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[local-appstream]
name=Redhat - local - AppStream
baseurl=file:///media/redhat/AppStream
file:///media/cdrom/AppStream
file:///media/cdrecorder/AppStream
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[root@redhatos ~]#
2、开启仓库，将 “enabled=0”， 改为“enabled=1”。
三、测试本地源仓库：
[root@redhatos ~]# dnf clean all
13 files removed
[root@redhatos ~]# dnf makecache
Redhat - local - BaseOS 69 MB/s | 2.3 MB 00:00
Redhat - local - AppStream 82 MB/s | 6.8 MB 00:00
