Rocky Linux 搭建本地源方法如下：
首先下载 Rocky Linux 的光盘镜像，官网下载地址：https://rockylinux.org/download/ 下载到的文件名为：Rocky-8.4-x86_64-dvd1.iso，我们暂时先放到/root 目录下。
创建挂载光盘镜像的目录并挂载iso到目录上：
mkdir -p /media/Rocky
mount -o loop Rocky-8.4-x86_64-dvd1.iso /media/Rocky
修改/etc/yum.repos.d/ 里的Rocky-AppStream.repo，Rocky-baseOS.repo关闭和Rocky-Media.repo启用配置，内容如下
[root@mgt yum.repos.d]# vim Rocky-AppStream.repo

# Rocky-Media.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.
[media-baseos]
name=Rocky Linux $releasever - Media - baseOS
baseurl=file:///media/Rocky/baseOS
file:///media/cdrom/baseOS
file:///media/cdrecorder/baseOS
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
[media-appstream]
name=Rocky Linux $releasever - Media - AppStream
baseurl=file:///media/Rocky/AppStream
file:///media/cdrom/AppStream
file:///media/cdrecorder/AppStream
gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
上述配置文件保存后，执行：
yum clean all
yum makecache
可以再 yum install cmake 之类的软件包安装一下试试。
