功能概述
reposync 工具是 DNF 工具包中的一个插件，使用 reposync 命令将 DNF 远程仓库的包同步到本地目录，在本地制作远程仓库的副本。
功能介绍
1、安装所需软件 reposync
安装reposync命令为
#
yum -y install dnf-plugins-core2、reposync 语法及参数说明
2.1、reposync 语法
dnf reposync $命令参数
reposync $命令参数
2.2、reposync 参数说明
—repo, —repoid
指定仓库标识符 id
-p, —download-path
指定下载远程仓库到本地存放的位置,缺省下载到当前目录
--download-metadata
下载所有存储库元数据。下载的副本可以立即用作存储库，不需要 createrepo_c 重建索引
--metadata-path
指定元数据下载路径，缺省下载到—download-path 目录下 -n,
--newest-only
仅下载仓库中更新的包，可用作增量同步仓库
--delete
删除本地未在远程仓库存在的包 -u,
--urls
仅打印软件包的下载地址，不进行下载操作
--remote-time
尝试将下载文件的时间戳修改为远程文件时间
3、同步前准备工作
3.1、存储
同步仓库前需要预留足够大的存储空间，根据需要同步的仓库大小来判断
[root@localhost ~]# yum repoinfo --all
Last metadata expiration check: 0:17:35 ago on 2022 年 05 月 25 日 星期三 16 时 33 分 37 秒.
Repo-id : UnionTechOS-Server-20
Repo-name : UnionTechOS-Server-20-1050
Repo-status : enabled
Repo-revision : 1645520402
Repo-updated : 2022 年 02 月 22 日 星期二 17 时 00 分 02 秒
Repo-pkgs : 2,004
Repo-available-pkgs: 2,004
Repo-size : 2.8 G #这是仓库的容量
Repo-baseurl : https://euler-packages.chinauos.com/server-euler/fuyu/1050/OS/x86_64
Repo-expire : 172,800 second(s) (last: 2022 年 05 月 25 日 星期三 16 时 33 分 37 秒)
Repo-filename : /etc/yum.repos.d/UnionTechOS-x86_64.repo
创建存放仓库的位置
mkdir /mnt/store
3.2、确认需要同步的仓库 ID
[root@localhost ~]#
dnf repolist repo id repo nameUnionTechOS-Server-20 UnionTechOS-Server-20-1050
UnionTechOS-Server-20-everything UnionTechOS-Server-20-1050-everything
4、示例
4.1、全量同步
dnf reposync —repoid=$repoid -p $存储位置
[root@localhost ~]# dnf reposync --repoid=UnionTechOS-Server-20
--repoid=UnionTechOS-Server-20-everything -p /mnt/store/
