The following is a brief installation tutorial for Arch Linux. It assumes familiarity with the Arch Beginner's Guide and Installation Guide.
It will provide a system using LVM on LUKS.
Note that this guide assumes you are performing the install to /dev/sda. In
some cases, you may find that your USB install disk claimed /dev/sda and you
want to install to /dev/sdb. Confirm which disk is which before proceeding.
Boot into the Arch installer.
If your console font is tiny (HiDPI systems), set a new font.
$ setfont sun12x22
Connect to the Internet.
Verify that the system clock is up to date.
$ timedatectl set-ntp true
(bios mode)
$ parted -s /dev/sda mklabel msdos
$ parted -s /dev/sda mkpart primary 1MiB 513MiB
$ parted -s /dev/sda mkpart primary 1024MiB 100%
$ mkfs.ext2 /dev/sda1
$ mkfs.ext4 /dev/sda2
(UEFI mode) Create partitions for EFI, boot, and root.
$ parted -s /dev/sda mklabel gpt
$ parted -s /dev/sda mkpart primary fat32 1MiB 513MiB
$ parted -s /dev/sda set 1 boot on
$ parted -s /dev/sda set 1 esp on
$ parted -s /dev/sda mkpart primary 513MiB 1024MiB
$ parted -s /dev/sda mkpart primary 1024MiB 100%
$ mkfs.ext4 /dev/sda2
$ mkfs.fat -F32 /dev/sda1
Create and mount the encrypted root filesystem. Note that for UEFI systems this will be partition 3.
$ pvcreate /dev/sda3pc
$ vgcreate arch /dev/mapper/lvm
$ lvcreate -L 4G arch -n swap
$ lvcreate -L 30G arch -n root
$ lvcreate -l +100%FREE arch -n home
$ lvdisplay
$ mkswap -L swap /dev/mapper/arch-swap
$ mkfs.ext4 /dev/mapper/arch-root
$ mkfs.ext4 /dev/mapper/arch-home
$ mount /dev/mapper/arch-root /mnt
$ mkdir /mnt/home
$ mount /dev/mapper/arch-home /mnt/home
$ swapon /dev/mapper/arch-swap
(UEFI mode) Encrypt the boot partition using a separate passphrase from the root partition, then mount the boot and EFI partitions.
$ mkdir /mnt/boot
$ mount /dev/sda2 /mnt/boot
$ mkdir /mnt/boot/efi
$ mount /dev/sda1 /mnt/boot/efi
Optionally edit the mirror list.
$ vi /etc/pacman.d/mirrorlist
Install the base system.
$ pacstrap -i /mnt base base-devel net-tools wireless_tools dialog wpa_supplicant openssh git grub ansible
(UEFI mode) $ pacstrap /mnt efibootmgr
Generate and verify fstab.
$ genfstab -U -p /mnt >> /mnt/etc/fstab
$ less /mnt/etc/fstab
Change root into the base install and perform base configuration tasks.
$ arch-chroot /mnt /bin/bash
$ systemctl enable dhcpcd.service
$ systemctl enable sshd.service
$ passwd
Set your mkinitcpio.
# only for UEFI
$ sed -i 's/^HOOKS=.*/HOOKS="base udev autodetect modconf block keyboard lvm2 resume filesystems fsck"/' /etc/mkinitcpio.conf
# for both
$ mkinitcpio -p linux
Configure GRUB.
# BIOS mode
$ grub-install /dev/sda
$ grub-mkconfig -o /boot/grub/grub.cfg
# UEFI mode
$ grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub --recheck
$ grub-mkconfig -o /boot/grub/grub.cfg
$ chmod -R g-rwx,o-rwx /boot
Cleanup and reboot!
$ exit
$ umount -R /mnt
$ reboot
Run ansible!
