Server

These scripts set up a server with ArchLinux and Btrfs

Arch Linux

Download the latest iso from https://www.archlinux.org/download, and load it onto a bootable USB drive

Insert the USB drive into the machine, turn it on, and select the USB drive as the boot device

Internet

Verify that the internet works by running

ping -c 4 google.com

If there are problems, go here

System Clock

timedatectl set-ntp true

Verify everything worked with

timedatectl status

Btrfs

Assuming drives /dev/sd[a-d]

mkfs.btrfs -L main -m raid10 -d raid10 /dev/sda /dev/sdb /dev/sdc /dev/sdd

mount -t btrfs /dev/sda /mnt

btrfs subvolume create /mnt/@        # root
btrfs subvolume create /mnt/@boot    # boot
btrfs subvolume create /mnt/@home    # home

umount /mnt

mount -t btrfs -o noatime,autodefrag,compress-force=lzo,space_cache,subvol=@ /dev/sda /mnt

mkdir /mnt/boot
mount -t btrfs -o noatime,autodefrag,compress-force=lzo,space_cache,subvol=@boot /dev/sda /mnt/boot

mkdir /mnt/home
mount -t btrfs -o noatime,autodefrag,compress-force=lzo,space_cache,subvol=@home /dev/sda /mnt/home

Install Packages

Update /etc/pacman.d/mirrorlist by using Pacman Mirrorlist Generator

Afterwards, install the base and base-devel packages

pacstrap -i /mnt base base-devel

This part will take 5-10 minutes

Fstab

genfstab -L /mnt >> /mnt/etc/fstab

Modify /mnt/etc/fstab and simplify subvolume references. For example, replace subvolid=##,subvol=/@,subvol=@ with subvol=@

Change root

arch-chroot /mnt /bin/bash

Hostname

echo computer_name > /etc/hostname

Timezone

ln -s /usr/share/zoneinfo/America/Los_Angeles /etc/localtime

Locales

echo LANG=en_US.UTF-8 > /etc/locale.conf

mkinitcpio Ram Disk

mkinitcpio -p linux

Password

passwd

Boot Loader

pacman -S grub
grub-install /dev/sda
grub-mkconfig -o /boot/grub/grub.cfg

Reboot

exit
umount -R /mnt
reboot

At this point, remove the USB flash drive from the server

Basic Requirements

Start dhcpcd on boot

systemctl enable dhcpcd
systemctl start dhcpcd

Get btrfs-progs to manage snapshots

pacman -S btrfs-progs

Create snapshots of all subvolumes

mkdir /btrfs
mount -t btrfs /dev/sda /btrfs

btrfs subvolume snapshot -r /btrfs/@ /btrfs/@--$(date --utc --iso-8601="seconds")
btrfs subvolume snapshot -r /btrfs/@boot /btrfs/@boot--$(date --utc --iso-8601="seconds")
btrfs subvolume snapshot -r /btrfs/@home /btrfs/@home--$(date --utc --iso-8601="seconds")

umount -R /btrfs
rmdir /btrfs

Start 'sshd' on boot

pacman -S openssh
systemctl enable sshd
systemctl start sshd

Install ZSH

pacman -S zsh zsh-completions
