本次介绍在Hyper-V虚拟机上安装Arch Linux的方法，其它虚拟机平台类似。

1. 创建和启动虚拟机

1.1 下载ArchLinux安装镜像

先登录官网下载页面：[https://archlinux.org/download/].

然后根据喜好选择具体的下载链接，比如我选择通过国内网易163下载镜像文件：

[http://mirrors.163.com/archlinux/iso/2022.06.01/archlinux-2022.06.01-x86_64.iso].

1.2 创建虚拟机

新建一个虚拟机，选择Generation 2的UEFI方式启动，接着设置内存2048M，存储50G，配置网卡(安装过程需要联网下载文件)，Installation Options选项中选择加载步骤1.1中下载的ISO文件。

点击完成后，就创建了一个虚拟机，选中虚拟机，鼠标右键选择"Settings -> Security"，禁用"Enable Secure Boot"功能，保存，启动虚拟机。

1.3 测试网络

启动完成之后，就进入了控制台界面，使用ping命令测试网络是否正常。

$ ping www.baidu.com -c 4

2. 分区

2.1 查看分区

$ fdisk -l
Disk /dev/sda: 50 GiB, 53687091200 bytes, 104857600 sectors
Disk model: Virtual Disk
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

Disk /dev/loop0: 688.21 MiB, 721641472 bytes, 1409456 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

2.2 创建分区

50G的存储空间，这里分为3个部分，如下表：

## 分区.
$ fdisk /dev/sda

Welcome to fdisk (util-linux 2.38).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x9842a669.

## 查看帮助.
$ Command (m for help): m

3. 格式化和挂载

3.1 格式化

## /dev/sda1格式化为FAT32格式.
$ mkfs.fat -F32 /dev/sda1
mkfs.fat 4.2 (2021-01-31)

## /dev/sda2格式化为SWAP.

3.2 挂载硬盘

$ mount /dev/sda3 /mnt
$ mkdir /mnt/boot
$ mount /dev/sd1 /mnt/boot
$ swapon /dev/sda2
$ lsblk -a

4. 安装系统

4.1 添加国内源

$ vim /etc/pacman.d/mirrorlist

在原有的Server基础上，增加两个：

Server = http://mirrors.163.com/archlinux/$repo/os/$arch
Server = https://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch

保存退出，更新源：

$ pacman -Syy
:: Synchronizing package databases...
 core                           156.4 KiB  23.1 KiB/s 00:07 [################################] 100%
 extra                         1717.5 KiB   198 KiB/s 00:09 [################################] 100%
 community                        6.7 MiB   226 KiB/s 00:30 [################################] 100%

4.2 安装系统

$ pacstrap /mnt base linux linux-firmware linux-headers base-devel

根据网速的不同,此过程需要一段不等的时间,我安装的这个版本需要下载558.64 MiB,如果中途出现断网等导致下载的情况,重新执行命令即可.

4.3 生成fstab

$ genfstab -U /mnt >> /mnt/etc/fstab

5. 系统配置

5.1 进入系统

$ arch-chroot /mnt

5.2 增加国内源

$ vim /etc/pacman.d/mirrorlist

增加两个国内源，其它源根据喜好自行添加：

Server = http://mirrors.163.com/archlinux/$repo/os/$arch
Server = https://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch

5.3 网络配置

安装网络工具:

$ pacman -S iw wpa_supplicant dialog net-tools networkmanager dhcpcd

安装完成后,进行配置网络:

$ systemctl enable NetworkManager
$ systemctl enable dhcpcd

5.4 用户配置

设置root密码:

$ passwd
New password: 
Retype new password: 
passwd: password updated successfully

添加新用户,示例添加一个名字叫test的新用户:

$ useradd -d /home/test -g root -m -s /bin/bash test
$ passed test
New password: 
Retype new password: 
passwd: password updated successfully

安装sudo:

$ pacman -S sudo vim
$ visudo

执行上述命令后,会自动打开/etc/sudoers,定位并编辑如下内容:

##
## User privilege specification
##
root ALL=(ALL:ALL) ALL

## 增加新建的test用户
test ALL=(ALL:ALL) ALL

## Uncomment to allow members of group wheel to execute any command
## 去掉注释
%wheel ALL=(ALL:ALL) ALL

5.5 安装Grub和efibootmgr

$ pacman -S grub efibootmgr
$ grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=ArchLinuxGrub
$ grub-mkconfig -o /boot/grub/grub.cfg

5.6 安装基础开发工具

$ pacman -S gcc make bc flex bison git openssh axel unzip bzip2 texinfo binutils patch python3

激活sshd:

$ systemctl enable sshd

5.7 完成安装

[root@archiso /]# exit
$ umount -R /mnt
$ poweroff

6. 启动系统

在Hyper-V此虚拟机中设置,移除安装镜像*.iso, CPU核心数默认是1个,可以适当增加,之后,启动虚拟机.
