安装BaseOS/AppStream包的方法。

找茬

挂载安装介质。

$ sudo mount CentOS-8.2.2004-x86_64-dvd1.iso /media
$ sudo ls -l /media/
$ sudo cp -v /media/media.repo /etc/yum.repos.d/centos8.repo
$ sudo chmod 644 /etc/yum.repos.d/centos8.repo
$ sudo ls -l /etc/yum.repos.d/centos8.repo

设置仓库

在`/etc/yum.repos.d/centos8.repo`中设置仓库。

修改之前

[InstallMedia]
name=CentOS Linux 8
mediaid=None
metadata_expire=-1
gpgcheck=0
cost=500

修改后

[Local-BaseOS]
name=CentOS-8 - Local - BaseOS
metadata_expire=-1
gpgcheck=1
enabled=1
baseurl=file:///media/BaseOS/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

[Local-AppStream]
name=CentOS-8 - Local - AppStream
metadata_expire=-1
gpgcheck=1
enabled=1
baseurl=file:///media/AppStream/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

额外软件包库 (EPEL)

安装EPEL包的方法。

下载

只需执行以下命令，次数与您想要下载的帖子数量相同。

wget -c -r -N --no-parent https://dl.fedoraproject.org/pub/epel/8/Everything/x86_64/

如果在在线环境下使用CentOS，使用reposync比使用wget更方便。

另外，数据容量大约为20GB左右。

设置存储库

将存储库设置在/etc/yum.repos.d/epel8.repo。

[Local-EPEL]
name=CentOS-8 - Local - EPEL
metadata_expire=-1
gpgcheck=0
enabled=1
baseurl=file:///mnt/host/epel/dl.fedoraproject.org/pub/epel/8/Everything/x86_64
# gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

确认

$ sudo dnf clean all
$ sudo dnf repolist
