Arch

• vmctl start -c -B cdrom <vm-name>

• Press <TAB>, then enter console=ttyS0,115200

• The problem may occur with loading /dev/disk/by-label/ARCH_<SMTH>

• To fix it you need to create /dev/disk/by-label/ if needed - mkdir -p /dev/disk/by-label/

• Then check blkid, and ln -s <path-to-iso-that-was-returned> /dev/disk/by-label/ARCH_<SMTH>

  ln -s /dev/sr0 /dev/disk/by-label/ARCH_202206

• exit from that console

• login as root

• check if network is working using ping archlinux.org

• timedatectl set-ntp true

• check what disk you need to format using fdisk -l

• run cfdisk <your-disk>

• choose dos

• partition scheme - 2G swap, 23G /, 25G /home

• mark root as bootable

• /dev/vda1 - swap, /dev/vda2 - /, /dev/vda3 - /home

• Formatting

• mkfs.ext4 -L ROOT /dev/vda2

• mkfs.ext4 -L HOME /dev/vda3

• mkswap -L SWAP /dev/vda1

• Mount

• mount /dev/vda2 /mnt

• mkdir -p /mnt/home

• mount /dev/vda3 /mnt/home

• swapon /dev/vda1

• Installation process

• pacstrap /mnt base linux linux-firmware

• genfstab -U /mnt >> /mnt/etc/fstab

• arch-chroot /mnt

• ln -sf /usr/share/zoneinfo/UTC /etc/localtime

• hwclock --systohc

• install editor (for example: pacman -S vim)

• edit /etc/locale.gen and uncomment en_US.UTF-8 UTF-8

• locale-gen

• Create /etc/locale.conf and insert LANG=en_US.UTF-8

• Create /etc/hostname and insert hostname

• set root password using passwd

• Bootloader

• pacman -S syslinux

• syslinux-install_update -i -a -m

• Fix /boot/syslinux/syslinux.cfg

  • in lines with APPEND change root=/dev/sdaX to root=<your-root-partition>

  • in the end of APPEND lines add console=ttyS0,115200

  • you should fix it for both: and for arch section, and for archfallback section

• End of basic install

• exit from chroot

• umount -R /mnt

• poweroff

• Now boot your vm and connect to serial console using vmctl start -c <vm-name>

• Fix networking

• Create file /etc/systemd/network/20-wired.network and add this to it:

  [Match]

  Name=enp0s2

  [Network]

  Address=

  Gateway=

  Address=

  Gateway=

• systemctl enable systemd-networkd

• systemctl start systemd-networkd

• Fix /etc/resolv.conf

  • Add nameserver <gateway-ipv4-addr>

• Update your system using pacman -Syu

• Add your own user and add it to wheel group

• useradd -m -G wheel <username>

• Install and configure sudo

• pacman -S sudo

• Edit /etc/sudoers

  • Uncomment line this line %25wheel ALL=(ALL:ALL) ALL or this %25wheel ALL=(ALL:ALL) NOPASSWD: ALL, if you want to allow sudo without password

• Setup sshd

• pacman -S openssh

• Edit /etc/sshd/sshd_config

  • Change PasswordAuthentication field to no`

  • Change PermitRootLogin field to no

  • mkdir -m 700 /home/<your-user-home-dir>/.ssh

• Add your public key to /.ssh/authorized_keys

• systemctl enable sshd

• systemctl start sshd

• Try to connect to your server using ssh with key

• It is recommended to poweroff your VPS and turn it on using vmctl start <vm-name> (maybe you will need to wait around 30 seconds or more)

• If you having some issues with connecting, try to connect to serial console using vmctl console <vm-name>
