ext4 + grub
Install Arch Linux with the following settings.
| Settings | |
|---|---|
| Dual Booting | false |
| Filesystem | ext4 |
| Boot Loader | GRUB |
| Disk | single-disk |
| Disk Encryption | false |
ISO
Install
Keymaps
Change the keymap to the one you use for the installation. For a Japanese keyboard, use jp106.
loadkeys jp106
Time Settings
Execute the following command to use the NTP (Network Time Protocol).
timedatectl set-ntp true
Optimizing Mirrorlist
Optimize the mirror list using reflector to access mirror servers with fast access during installation.
pacman -Syy
pacman -S reflector
reflector -c Japan --sort rate -a 6 --save /etc/pacman.d/mirrorlist
The meaning of the reflector option is as follows.
| Options | Description |
|---|---|
-c Japan | Restrict mirrors to selected countries. |
--sort rate | Sort by download rate. |
-a 6 | Restrict to servers synchronized within 6 hours. |
--save /etc/pacman.d/mirrorlist | Save the mirror list to the specified path. |
Disk Partitioning and Formatting
Use gdisk to change the partition. In this example, we assume that Arch Linux is installed in /dev/sda.
gdisk /dev/sda
Allocate the first partition as an EFI partition of about 300MB. The remaining space will be allocated as a Linux Filesystem.
/dev/sda1: EFI system (300M)
/dev/sda2: Linux filesystem
EFI partition is formatted with fat.
mkfs.fat -F32 /dev/sda1
Linux Filesystem is formatted with ext4.
mkfs.ext4 /dev/sda2
Then mount devices like following.
mount /dev/sda2 /mnt
mount /dev/sda1 /mnt/boot
Base Install
Sometimes updating archlinux-keyring is needed.
pacman -Syy
pacman -S archlinux-keyring
Install packages in /mnt.
- Intel
- AMD
pacstrap /mnt base linux linux-firmware vim intel-ucode
pacstrap /mnt base linux linux-firmware vim amd-ucode
fstab
Generate the fstab file, which holds the information about which device to mount.
genfstab -U /mnt >> /mnt/etc/fstab
Change the Root Directory
Use chroot to set /mnt as the root directory.
arch-chroot /mnt
Localization
Create a symbolic link to /etc/localtime to change the time zone.
ln -sf /usr/share/zoneinfo/Asia/Tokyo /etc/localtime
Set the hardware clock to the current system clock. The system clock is the clock managed by the OS, and the hardware clock is the clock managed by the motherboard (hardware). when the OS is rebooted, the system clock stored in memory is lost, so the time is obtained from the hardware clock.
hwclock --systohc
To set the locale, first generate the locale. Uncomment the entries you want to use in /etc/locale.gen and run locale-gen.
sed -i 's/#en_US.UTF-8/en_US.UTF-8/' /etc/locale.gen
locale-gen
Execute the following command to set the locale of the system.
echo LANG=en_US.UTF-8 >> /etc/locale.conf
echo KEYMAP=jp106 >> /etc/vconsole.conf
Hostname
Register hostname in /etc/hostname.
echo arch > /etc/hostname
Edit /etc/hosts and set IP address corresponding to hostname.
echo -e "127.0.0.1\tlocalhost
::1\t\tlocalhost
127.0.1.1\tarch.localdomain\tarch" >> /etc/hosts
Root Password
Set the password of root user.
passwd
Install Additional Packages
pacman -S grub efibootmgr networkmanager network-manager-applet \
dialog os-prober mtools dosfstools base-devel linux-headers reflector \
git xdg-utils xdg-user-dirs bluez bluez-utils
Bootloader
Install Grub and create config file.
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB
grub-mkconfig -o /boot/grub/grub.cfg
Systemd
Enables NetworkManager.
systemctl enable NetworkManager
Enables Bluetooth.
systemctl enable bluetooth
Enables reflector. The execution options are written in /etc/xdg/reflector/reflector.conf.
systemctl enable reflector.service # update mirrorlist every boot
systemctl enable reflector.timer # update mirrorlist weekly
Add User
Add user with useradd and set the password.
useradd -mG wheel mori
passwd mori
Give the user priviledges.
EDITOR=vim visudo
- # %wheel ALL=(ALL) ALL
+ %wheel ALL=(ALL) ALL
Reboot
exit
umount -a
reboot
