篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了centos-stream8 制作YUM镜像仓库相关的知识，希望对你有一定的参考价值。
`思路：
机器A: 192.168.238.17
1. 找个"最小化安装的版本" 去下载软件包和依赖包，最小化的安装版本不会让你少下载某些依赖包
2. 使用createrepo制作软件仓库
3. 搭建httpd服务器创建lan repo
机器B：192.168.238.18
4. 配置需要安装软件包的服务器，指向搭建的软件仓库进行测试
---------------------------------------------------------------------------------------------------------------------------------------
机器A：
1.下载vim软件包和所需的依赖包
# 只下载不安装，且将下载的包保存到/root/download目录下
[root@localhost ~]# yum install vim --downloadonly --downloaddir /root/test -y
[root@localhost ~]# mkdir /root/download
[root@localhost ~]# cp /root/test/* /root/download/
[root@localhost ~]# cd /root/download/
[root@localhost download]# ls
gpm-libs-1.20.7-17.el8.x86_64.rpm vim-enhanced-8.0.1763-16.el8_5.12.x86_64.rpm
vim-common-8.0.1763-16.el8_5.12.x86_64.rpm vim-filesystem-8.0.1763-16.el8_5.12.noarch.rpm
[root@localhost download]# cd ..
[root@localhost ~]#
2. 使用createrepo制作软件仓库
#下载安装createrepo
[root@localhost ~]# yum install createrepo -y
#将download制作软件仓库
[root@localhost ~]# createrepo download
Directory walk started
Directory walk done - 4 packages
Temporary output repo path: download/.repodata/
Preparing sqlite DBs
Pool started (with 5 workers)
Pool finished
[root@localhost ~]#
# 进入到download中，发现产生了元数据repodata，repodata创建出来，目录名称和文件位置都是不可以改变的，如需改变需要改变后重新createrepo，重新生成repodate
[root@localhost ~]# ls download/
gpm-libs-1.20.7-17.el8.x86_64.rpm vim-enhanced-8.0.1763-16.el8_5.12.x86_64.rpm
repodata vim-filesystem-8.0.1763-16.el8_5.12.noarch.rpm
vim-common-8.0.1763-16.el8_5.12.x86_64.rpm
3. 搭建httpd服务器创建lan repo
#软件仓库做好了，需要搭建仓库环境，将仓库共享出来，别人才可以访问下载
[root@localhost ~]# yum install httpd -y
[root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# ls
autoindex.conf README userdir.conf welcome.conf
[root@localhost conf.d]# mv welcome.conf welcome.conf.bak
[root@localhost conf.d]# cd
[root@localhost ~]# cp -ra download/ /var/www/html/
[root@localhost ~]# systemctl enable httpd --now
Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# setenforce 0
[root@localhost ~]#
#这个时候用命令行curl是可以看到 download目录的，也可以图形化访问IP地址，如下图
[root@localhost ~]# curl 192.168.238.17
