arch

NOTE: This guide assumes that you have 50G disk for your vm

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
- Change PubkeyAuthentication field to yes
- Make in your user's home dir folder .ssh with 700 permissions
- 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>
