制作CentOS-8-最小系统(LoongArch)

// 先设置成英文环境

Errors during downloading metadata for repository ;baseos;:
  - Status code: 404 for http://pkg.loongnix.cn/loongnix-server/8/BaseOS/loongarch64/release/repodata/repomd.xml (IP: 114.242.206.182)
Error: Failed to download metadata for repo ;baseos;: Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

从错误信息可知是下载repomd.xml 文件失败;打这个网址确实出错;原因是LoongArch 没有8.0 的版本有8.3和8.4版本;所以将版本号改为 8.3

[root;master rootfs]# dnf --releasever 8.3   --disablerepo=* --enablerepo=baseos --installroot=;$(pwd)/rootfs; groups install ;Minimal Install; 2>&1| tee dnf-rootfs.log

Complete!

安装完成

[root;master rootfs]# ls
dnf-rootfs.log  rootfs
[root;master rootfs]# du -sh rootfs
1.3G    rootfs
[root;master rootfs]# chroot rootfs/
[root;master /]# ls
bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[root;master /]# exit
exit
[root;master rootfs]#

dnf-rootfs.log 记录了所有包的下载;安装;校验的过程

制作完的系统通过chroot可以正常使用;就是体积点大;可以通过减少一些包来进行空间的压缩。
