Arch Linux install to BIOS boot system

Install Arch Linux under the following conditions.


Creating and booting USB installation media

Download the ISO file ʻ` from the official Download ArchLinux page.

Write the ISO file to the USB memory using the dd command.

# dd bs=4M if=/path/to/archlinux.iso of=/dev/sdy status=progress && sync

When the USB installation media is complete, boot the live environment from the USB installation media.

Arch Linux installation

Create partition

root@archiso ~ # parted /dev/sdx
(parted)mklabel msdos
(parted)mkpart primary ext4 1MiB 100MiB //[/boot]For directories
(parted)mkpart primary ext4 100MiB 100% //[/]For directories

Initialize the created partition.

root@archiso ~ # mkfs.ext4 /dev/sdx1 
root@archiso ~ # mkfs.ext4 /dev/sdx2

Mount the created partition.

root@archiso ~ # mount /dev/sdx2 /mnt
root@archiso ~ # mkdir /mnt/boot
root@archiso ~ # mount /dev/sdx1 /mnt/boot

Time setting

root@archiso ~ # timedatectl set-ntp true
root@archiso ~ # timedatectl set-timezone Asia/Tokyo

Select a mirror list to install the ArchLinux package (select a Japanese server)

root@archiso ~ # vim /etc/pacman.d/mirrorlist
root@archiso ~ # cat /etc/pacman.d/mirrorlist
## Arch Linux repository mirrorlist
## Filtered by mirror score from mirror status page
## Generated on 20xx-xx-xx

## Japan
Server =$repo/os/$arch
## Japan
Server =$repo/os/$arch
## Japan
Server =$repo/os/$arch
## other country

Installation of base system and required packages

root@archiso ~ # pacstrap /mnt base linux vim dhcpcd

Create an fstab to determine the disk using the UUID.

root@archiso ~ # genfstab -U /mnt >> /mnt/etc/fstab
root@archiso ~ # cat /mnt/etc/fstab
# Static information about the filesystems.
# See fstab(5) for details.

# <file system> <dir> <type> <options> <dump> <pass>
# /dev/sdx2
UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx       /               ext4            rw,relatime     0 1

# /dev/sdx1
UUID=yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy       /boot           ext4            rw,relatime     0 2

Chroot to the installed environment

root@archiso ~ # arch-chroot /mnt

Time zone and time settings

[root@archiso /]# ln -sf /usr/share/zoneinfo/Asia/Tokyo > /etc/localtime
[root@archiso /]# hwclock --systohc

Setting the character code to use

[root@archiso /]# vim /etc/locale.gen
[root@archiso /]# cat /etc/locale.gen
en_US.UTF-8 UTF-8
ja_JP.UTF-8 UTF-8
[root@archiso /]# locale-gen
[root@archiso /]# vim /etc/locale.conf
[root@archiso /]# cat /etc/locale.conf

Hostname settings

[root@archiso /]# vim /etc/hostname
[root@archiso /]# cat /etc/hostname

Network settings

[root@archiso /]# vim /etc/hosts
[root@archiso /]# cat /etc/hosts localhost
::1    localhost myhostname.localdomain	myhostname

root password setting

[root@archiso /]# passwd

Bootloader installation and configuration

[root@archiso /]# pacman -S grub os-prober intel-ucode
[root@archiso /]# grub-install --target=i386-pc --recheck /dev/sdx
[root@archiso /]# grub-mkconfig -o /boot/grub/grub.cfg

Set to connect to the network at boot time

[root@archiso /]# systemctl enable dhcpcd

Log out of chroot and reboot

[root@archiso /]# exit
root@archiso ~ # umount -R /mnt
root@archiso ~ # reboot

Initial settings after installing Arch Linux

Log in as root

myhostname login : root

Create a local user

[root@myhostname ~]# useradd -m -G wheel -s /bin/bash myusername
[root@myhostname ~]# passwd myusername

Install sudo so that users in the wheel group can use sudo.

[root@myhostname ~]# pacman -S sudo
[root@myhostname ~]# vim /etc/sudoers
[root@myhostname ~]# cat /etc/sudoers
## User privilege specification
root ALL=(ALL) ALL

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

Login as a local user

[root@myhostname ~]# exit
myhostname login : myusername

Install and enable openssh

[myusername@myhostname ~]# sudo pacman -S openssh
[myusername@myhostname ~]# sudo systemctl enable sshd


I installed Arch Linux in the environment booted by BIOS boot and set it up to the point where it can be operated from the outside with ssh. Detailed explanation is [Installation Guide-ArchWiki]( See% 83% BC% E3% 83% AB% E3% 82% AC% E3% 82% A4% E3% 83% 89).
