How to manually install alpine Linux on any Linux distribution


You can easily change these factors when you notice them, for example in the alpine rootfs you can always change the version, or in timezone, well time timezone, the drive whenever it comes up, though networking is needed here

Installation (pt. 1)

Installation (pt. 2)

Mount root

mkdir -p /mnt/alpine
mount /dev/sda3 /mnt/alpine

Mount boot

mkdir -p /mnt/alpine/boot
mount /dev/sda1 /mnt/alpine/boot

Download an extract the RootFS

cd /mnt/alpine
tar xpvf alpine-minirootfs-3.16.2-x86_64.tar.gz --xattrs-include='*.*' --numeric-owner

FSTAB generation

sh genfstab -U /mnt/alpine >>/mnt/alpine/etc/fstab
cat /mnt/alpine/etc/fstab
echo "$(blkid /dev/sda2 | awk '{print $2}' | sed 's/"//g') none swap sw 0 0" >>/mnt/alpine/etc/fstab

Mount the needed fake filesystems

mount --types proc /proc /mnt/alpine/proc
mount --rbind /sys /mnt/alpine/sys
mount --make-rslave /mnt/alpine/sys
mount --rbind /dev /mnt/alpine/dev
mount --make-rslave /mnt/alpine/dev
mount --bind /run /mnt/alpine/run
mount --make-slave /mnt/alpine/run

Copy host's resolv.conf to the chroot environment

cp /etc/resolv.conf /mnt/alpine/etc/resolv.conf


chroot /mnt/alpine /bin/ash

Setup PATH

export PATH='/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'

Update and install setup scripts

apk update
apk add alpine-conf openrc --no-cache

Installation (pt. 3)

If you see any errors regarding rc-service, rc-update, etc. ignore them

This part is based off

Setup keymap

setup-keymap us us  # This will use the US keyboard

Setup hostname

export HOSTNAME='alpine'
setup-hostname "$HOSTNAME"  # Hostname will be alpine

Setup hosts file

tee /etc/hosts <<EOF localhost.localdomain localhost $HOSTNAME.localdomain $HOSTNAME
::1       localhost.localdomain localhost $HOSTNAME.localdomain $HOSTNAME

Setup networking


apk add tzdata
export _TZ='Europe/Vilnius'
install -Dm 0644 "/usr/share/zoneinfo/$_TZ" "/etc/zoneinfo/$_TZ"
export TZ="$_TZ"
echo "export TZ='$TZ'" >> /etc/profile.d/

Root password


Networking tools

apk add dhcp wpa_supplicant

Bootloader (GRUB) and kernel

apk add grub grub-efi efibootmgr linux-lts
apk add linux-firmware
grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=ALPINE
grub-mkconfig -o /boot/grub/grub.cfg

Enable vital services

rc-update add hostname boot
rc-update add devfs sysinit
rc-update add cgroups sysinit
rc-update add bootmisc boot
rc-update add binfmt boot
rc-update add fsck boot
rc-update add urandom boot
rc-update add root boot
rc-update add procfs boot
rc-update add swap boot
rc-update add sysfs sysinit
rc-update add localmount boot
rc-update add sysctl boot

Make grub use a menu

tee -a /etc/default/grub <<EOF
GRUB_CMDLINE_LINUX="rootfstype=ext4 loglevel=3"
grub-mkconfig -o /boot/grub/grub.cfg

Exiting the installation

umount -a
