use dnf with metalink

使用metalink提升dnf软件包安装速度
背景
目前openeuler系统中，dnf安装软件包默认使用的是baseurl方式，以openEuler-23.03的OS软件仓为例，配置如下：
[OS]
name=OS
baseurl=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/RPM-GPG-KEY-openEuler
baseurl方式是直接指定下载软件包访问的站点，repo.openeuler.org站点服务器在香港。使用baseurl有许多缺点：
- 单点故障——出现故障后影响所有软件包的安装
- 带宽受限——一个站点的出口带宽无法满足大量用户同时安装软件包
- 网络问题——国内或者欧美等地域，访问香港站点速度缓慢
为解决以上问题，推荐使用metalink替换baseurl。
metalink原理简介
还是以openEuler-23.03的OS软件仓为例，修改为metalink方式如下：
[OS]
name=OS
baseurl=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/
metalink=https://mirrors.openeuler.org/metalink?repo=$releasever/OS&arch=$basearch
metadata_expire=1h
enabled=1
gpgcheck=1
gpgkey=http://repo.openeuler.org/openEuler-23.03/OS/$basearch/RPM-GPG-KEY-openEuler
dnf客户端访问metalink链接地址，metalink服务器会根据主机ip地址、镜像站点出口带宽、运营商等参数进行运算，从所有镜像站中选择主机访问最快的若干镜像站，按照优先级排序，然后将该镜像站列表返回给dnf客户端，dnf将该列表文件缓存到本地。之后dnf根据特定的算法从站点列表下载软件包。
注：openEuler总共有27个镜像站点，遍布亚洲、欧洲各地，具体可通过以下地址查阅 https://www.openeuler.org/en/mirror/list/
metalink vs baseurl
为了验证metalink的实际效果，与baseurl在安装软件包速度方面作一个简单的对比测试。
测试步骤：
- 以docker容器方式运行系统openEuler-23.03并进入容器
- 执行dnf install golang命令安装golang软件包及依赖（共242MB）
- 记录从输入确认信息到所有包下载完成的时间
不同地域的主机重复以上步骤，分别以metalink和baseurl方式执行三次，结果如下：
| 主机IP | 主机所在地 | 主机带宽 | 安装方式 | 第一次 | 第二次 | 第三次 |
| 123.60.110.6 | 上海 | 100Mb | baseurl | 12m14s | 10m22s | 13m11s |
| metalink | 20s | 25s | 25s | |||
| 139.9.250.51 | 贵阳 | 100Mb | baseurl | 9m33s | 10m29s | 10m11s |
| metalink | 20s | 20s | 20s | |||
| 139.159.199.31 | 深圳 | 100Mb | baseurl | 2m40s | 2m26s | 2m20s |
| metalink | 2m14s | 3m12s | 2m23s | |||
| 101.44.36.113 | 土耳其 | 100Mb | baseurl | 35s | 34s | 35s |
| metalink | 35s | 25s | 33s | |||
| 13.39.48.16 | 巴黎 | 无限制 | baseurl | 60m+ | 60m+ | 60m+ |
| metalink | 58s | 52s | 56s | |||
| 18.197.160.221 | 德国 | 无限制 | baseurl | 60m+ | 60m+ | 60m+ |
| metalink | 45s | 48s | 49s | |||
| 44.205.20.228 | 美国 | 无限制 | baseurl | 60m+ | 60m+ | 60m+ |
| metalink | 24s | 18s | 22s |
注：12m14s代表12分14秒，60m+代表耗时超过60分钟，未具体记录。
由统计数据可见，metalink在任何情况下均不逊色于baseurl，在国内以及欧洲表现突出，下载速度有质的提高。
各版本openEuler.repo配置
现列出openEuler系统各版本的metalink配置，用户可按需修改，文件路径/etc/yum.repos.d/openEuler.repo。
注：openEuler-20.09、openEuler-21.03、openEuler-21.03以及openEuler-20.03-LTS已停止维护。
