Arch Linux install

Arch Linux, bspwm, sxhkd, dmenu_run.pl, xfce4-panel, urxvt(c), zsh, vim

Setup, format, bootstrap, chroot

  1. arch linux install from archiso usb drive
  2. requires network connectivity, possibly wired, to be available
  1. set keyboard for UK qwerty

loadkeys /usr/share/kbd/keymaps/i386/qwerty/uk.map.gz

  1. check for potentially failed services (i.e. network dhcp)

systemctl --failed

  1. turn ntp time updates on

timedatectl set-ntp true

  1. create drive partitions

cfdisk

  1. see also https://wiki.archlinux.org/index.php/Partitioning
  2. there can be only 4 'primary' partitions
  3. make the fourth 'extended' so it can contain further 'logical' partitions
  4. only primary and logical partitions are formatted
  1. / - root partition, will contain /usr (includes installed programs) - 20/25Gb - Bootable - Type: linux (83)
  2. /boot - contains boot kernel images, 100Mb for no extra kernel images, 200Mb safer for additional images (linux-ck, linux-lts, etc.) - Type: linux (83)
  3. /var - contains misc. including spools, logs, packages downloaded for installation. separate to avoid running out of space. 10Gb
  4. /home - contains user home folders, where media will be stored - size: remainder Type: linux (83)
  5. [swap] - swap partition - 1Gb - Type: linux swap (82)
  1. check and format drive partitions

lsblk

mkfs.ext4 /dev/[partition]

  1. repeat for each partition, excluding swap
  1. create swap partition

mkswap /dev/[swappartition] swapon /dev/[swappartition]

  1. mount partitions

mount /dev/sda1 /mnt

mkdir /mnt/boot mount /dev/sda2 /mnt/boot

mkdir /mnt/var mount /dev/sda3 /mnt/var

mkdir /mnt/home mount /dev/sda5 /mnt/home

  1. use geographically close arch package mirror

vi /etc/pacman.d/mirrorlist

  1. put selected mirror at top of the list. this is copied across in the next step
  1. install pacman and bootstrap

pacstrap /mnt base bade-devel vim

  1. generate file system configuration info

genfstab -p /mnt >> /mnt/etc/fstab

  1. chroot into new system

arch-chroot /mnt

Configuration

# set root user password
passwd

# add your own user account and set a password
useradd -m [USERNAME]
passwd [USERNAME]

# let wheel group use sudo for root permission

## USERNAME HOST_NAME= NOPASSWD: /usr/bin/halt,/usr/bin/poweroff,/usr/bin/reboot,/usr/bin/pacman -Syu

# add user to wheel group for sudo/etc, access
gpasswd -a [USERNAME] wheel


# set a hostname
echo computer_name > /etc/hostname

# set timezone
ln -s /usr/share/zoneinfo/Europe/London /etc/localtime

# uncomment en_GB.UTF-8 or appropriate locale
vim /etc/locale.gen
/#en_GB
xZZ

# generate locale
locale-gen

[esc]ZZ

Images

# uncomment COMPRESSION="xz" in /etc/mkinitcpio.conf

# build boot images
mkinitcpio -p linux

# install lts kernel
pacman -S linux-lts

# install a bootloader. tried syslinux before, trying grub now. first impression, syslinux is cleaner.
pacman -S grub
grub-install --recheck --target=i386-pc /dev/sdx

# allow for saving the last booted kernel, edit /etc/default/grub, set
GRUB_DEFAULT=saved
# and add
GRUB_SAVEDEFAULT=true

# generate/regenerate config file
grub-mkconfig -o /boot/grub/grub.cfg

# syslinux route instead; will require some *.c32 symbolic links


# install wpa_supplicant for later wifi setup
pacman -S wpa_supplicant

# reboot
# ctrl-alt-del is quickest

Network

# set network device names in relation to their MAC
vim /etc/udev/rules.d/10-network.rules

echo 'SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="$(cat /sys/class/net/ethernetinterfacename/address)", NAME="eth0"' > /etc/udev/rules.d/10.network.rules
echo 'SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="$(cat /sys/class/net/wifiinterfacename/address)", NAME="wlan0"' >> /etc/udev/rules.d/10.network.rules

# setup netctl (arch dev grown systemd interface)
cp /etc/netctl/examples/ethernet-dhcp /etc/netctl
cp /etc/netctl/examples/wireless-wpa /etc/netctl
vim /etc/netctl/wireless-wpa
# change essid and key

# test netctl ethernet profile
netctl start ethernet-dhcp
ip a
ping bbc.co.uk
netctl stop ethernet-dhcp

# test netctl wireless-wpa profile
netctl start ethernet-dhcp
ip a

netctl stop wireless-wpa

# make ethernet profile persistant

Install

* archinstaller - Automated installation script for arch linux written in bash. It works similar to preseeding the debian installer d-i.

* FAI is a non-interactive system to install, customize and manage Linux systems and software configurations on computers as well as virtual machines and chroot environments, from small networks to large-scale infrastructures like clusters and cloud environments. It's a tool for unattended mass deployment of Linux. You can take one or more virgin PC's, turn on the power, and after a few minutes, the systems are installed, and completely configured to your exact needs, without any interaction necessary.
