In Ubuntu OR any other Free tier Linux OS ````shell # Download Alpine Linux and install it on disk cd / wget https://dl-cdn.alpinelinux.org/alpine/v3.16/releases/x86_64/alpine-virt-3.16.2-x86_64.iso dd if=alpine-virt-3.16.2-x86_64.iso of=/dev/sda sync reboot ```` 2. In Alpine Linux (via Oracle Console Connection / Cloud Shell) * Wait for Alpine Linux to boot * Press Enter to see login prompt * Login as 'root' with no password. 3. Bring up networking in Alpine ````shell vi /etc/network/interfaces ```` add: ````conf auto eth0 iface eth0 inet dhcp ```` then in shell: ````shell /etc/init.d/networking restart ```` 4. Setup SSH in Alpine ````shell # in setup-sshd type 'yes' to 'Allow root ssh login?' # OR if you want to be more secure then setup ssh authorized_keys setup-sshd # setup root password for remote login passwd ```` Now you can ssh to your instance remotely ````shell ssh root@INSTANCE_IP ```` 5. Move Alpine from disk to RAM ````shell mkdir /media/setup cp -a /media/sda/* /media/setup mkdir /lib/setup cp -a /.modloop/* /lib/setup /etc/init.d/modloop stop umount /dev/sda mv /media/setup/* /media/sda/ mv /lib/setup/* /.modloop/ ```` 6. Setup APK repositories and get the Arch installation scripts, pacman and other required tools ````shell setup-apkrepos # enable community repository to fetch pacman etc. vi /etc/apk/repositories apk update apk add arch-install-scripts pacman dosfstools e2fsprogs ```` 7. Partition the disk and mount the partitions ````shell fdisk /dev/sda ```` in fdisk: (TIP: You may have to first delete all partitions using 'd' and then 'w' (save) and then proceed with following): ```` Press "g" (use gpt table) Press "n", partition 15, First sector default, Last sector +512M (set esp/EFI partition 15, size 512M) Press "t", then "1" (set type as EFI System) Press "n", partition 1 (set root partition 1, size remaining) Press "w" (save the changes) ```` then in shell: ````shell partprobe mkfs.vfat /dev/sda15 mkfs.ext4 /dev/sda1 mount /dev/sda1 /mnt mkdir -p /mnt/boot/EFI mount /dev/sda15 /mnt/boot/EFI ```` 8. Prepare Arch bootstrap (1GB RAM is not enough so we use HDD) ````shell mkdir /mnt/tmp cd /mnt/tmp wget -c https://mirror.cs.pitt.edu/archlinux/iso/2022.09.03/archlinux-bootstrap-2022.09.03-x86_64.tar.gz tar xf archlinux-bootstrap-2022.09.03-x86_64.tar.gz # uncomment any one mirror vi root.x86_64/etc/pacman.d/mirrorlist arch-chroot root.x86_64 # now we are inside Arch Installation process (as if booted through Arch ISO / Boot medium) pacman-key --init pacman-key --populate archlinux ```` 9. Install Arch on /mnt ````shell mount /dev/sda1 /mnt mount /dev/sda15 /mnt/boot/EFI pacstrap /mnt base linux linux-firmware amd-ucode e2fsprogs openssh vim grub efibootmgr genfstab -U /mnt >> /mnt/etc/fstab ```` 10. Configure the Arch system ```` arch-chroot /mnt # now we are inside our actual Arch system which we will be using in future # setup root password incase of serial console (see below) based recovery is required passwd # Setup swap (4GB) dd if=/dev/zero of=/swapfile bs=1M count=4096 status=progress chmod 600 /swapfile mkswap /swapfile echo '/swapfile none swap defaults 0 0' >> /etc/fstab # Configure the services systemctl enable systemd-networkd systemd-timesyncd sshd systemctl set-default multi-user.target # Basic Arch configuration ln -sf /usr/share/zoneinfo/YOURREGION/YOURCITY /etc/localtime hwclock --systohc # uncomment your locale(s) vim /etc/locale.gen locale-gen echo 'LANG=en_US.UTF-8' >> /etc/locale.conf echo 'TYPE_YOUR_HOSTNAME_HERE' >> /etc/hostname # sshd: PermitRootLogin with authorized_keys sed -i -e 's/^#PermitRootLogin/PermitRootLogin/g' /etc/ssh/sshd_config mkdir -p /root/.ssh chmod 700 /root/.ssh echo 'ssh-ed25519 TYPE_YOUR_SSH_KEY_HERE root@localhost' >> /root/.ssh/authorized_keys chmod 600 /root/.ssh/authorized_keys ```` 11. Configure Networking (DHCP) ````shell echo -e 'search localdomain\nnameserver 1.1.1.1\nnameserver 1.0.0.1' >> /etc/resolv.conf vim /etc/systemd/network/20-ethernet.network ```` add: ````conf [Match] Name=en* Name=eth* [Network] DHCP=yes IPv6PrivacyExtensions=yes [DHCPv4] UseDNS=false UseNTP=false [DHCPv6] UseDNS=false UseNTP=false [IPv6AcceptRA] UseDNS=false UseDomains=false ```` 12. Setup the Serial Console (ttyS0) This step is optional but helpful to get instance Console (ttyS0) / Cloud Shell access (via https://cloud.oracle.com) in case the system is not accessible via SSH or not booting. ````shell vim /etc/default/grub ```` append: ````conf GRUB_TERMINAL_INPUT="console serial" GRUB_TERMINAL_OUTPUT="gfxterm serial" GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200" GRUB_CMDLINE_LINUX_DEFAULT="${GRUB_CMDLINE_LINUX_DEFAULT/quiet/}" GRUB_CMDLINE_LINUX_DEFAULT="${GRUB_CMDLINE_LINUX_DEFAULT} console=tty0 console=ttyS0,115200" ```` 13. Configure EFI boot ````shell grub-install --efi-directory=/boot/EFI --bootloader-id=GRUB # create fallback boot loader too mkdir -p /boot/EFI/EFI/BOOT cp -dp /boot/EFI/EFI/GRUB/grubx64.efi /boot/EFI/EFI/BOOT/BOOTX64.EFI grub-mkconfig -o /boot/grub/grub.cfg ```` Also follow Arch Installation guide for any other steps that you may require: https://wiki.archlinux.org/index.php/installation_guide#Configure_the_system 14. Reboot and boot to your Arch!
